BQE Water Inc, a leader in the treatment and management of mine impacted waters, has been awarded a contract for the design, construction and operation of a SART (sulphidisation, acidification, recycling and thickening) plant to improve gold leaching efficiency and overall cyanide management at a gold metallurgical facility in Shandong Province, China, owned by Shandong Gold Mining.

With a contract structure similar to two previous SART plants in the province signed in 2019 that are now in operation with support services from BQE Water, this contract has two project phases. The first involves engineering design, procurement, construction, plant commissioning and start-up. The second is for on-site operations support services for an initial period of five years in exchange for a quarterly service fee based on plant performance.

“The Shandong Gold contract solidifies our leadership position with the SART process technology not only in China but globally,” David Kratochvil, President & CEO of BQE Water, said. “Cyanide management needs are on the rise from the mining of more deposits containing mineralisation that interferes with gold leaching and the increased industry focus for projects to be environmentally responsible and socially acceptable. Through the capabilities of our team, we are committed to supporting the gold mining and smelting sector in meeting their project requirements.”

Songlin Ye, Vice President for Asia at BQE Water, adds: “The fact that Shandong Gold sole-sourced the project from BQE Water speaks volumes about our SART expertise. And with the backing of three SART plants for the three largest gold producers in the region, we look forward to further growing our cyanide management market in China and Asia in general.”

BQE Water says it is a global leader in the SART process which enables cyanide consumed by base metals to be recovered and recycled, lowering the cost of gold extraction and reducing the environmental footprint of gold mining projects. The company also provides solutions to manage the by-products of cyanidation and cyanide destruction such as ammonia, nitrite and thiocyanate removal.

BQE Water says it has advanced the SART plant it designed for a gold metallurgical facility owned by Shandong Zhongkuang Group Co Ltd, in China, to full production.

Located in the Shandong Province in eastern China, the plant is now being operated under the ongoing technical supervision of BQE Water.

Implementing SART (sulphidisation, acidification, recycling and thickening) at the site improves both the environmental performance and project economics of the metallurgical facility, BQE said. Specifically, the SART plant eliminates the need for cyanide destruction, recovers copper and zinc as separate sulphide concentrates, and recycles free cyanide recovered by the plant to gold leaching.

BQE was awarded the SART plant contract back in 2019 following the positive outcome of an engineering feasibility study and on-site testing completed by BQE Water earlier in the year.

The Zhongkuang SART plant also represents many firsts, according to BQE:

  • It is the first application of SART globally where the cyanide competing base metals, copper and zinc, are recovered simultaneously from the leach solution as two separate high-grade concentrates that can be sold to generate incremental revenues;
  • It is the first commercial scale application of SART in China;
  • It is the first SART plant where lime is used to control gas emissions to reduce operating costs and control the build-up of salts in the process water; and
  • It is the first SART plant to be integrated into a complex metallurgical flowsheet that combines mineral flotation with cyanidation and SART in a Zero Liquid Discharge metallurgical facility with complete water recycle.

Songlin Ye, Vice President for Asia at BQE Water, said: “We are very proud of our China-based operations team for this significant achievement and that they were able to do so considering the challenges associated with the COVID-19 pandemic. The Zhongkuang SART plant is our flagship project for the China gold sector and other gold producers in the country are taking notice.”

David Kratochvil, President & CEO of BQE Water, added: “The many firsts associated with the Zhongkuang SART plant demonstrates our leadership in SART technology. And through the unique combination of engineering know-how and operations expertise, the project also shows our ability to reduce risks and achieve predictable outcomes for our clients.”

BQE Water has signed two agreements with EcuaCorriente SA (ECSA), an Ecuador subsidiary of a Chinese consortium, to prepare an adaptive mine water management plan and to improve the design of an existing water treatment plant for the El Mirador mine the consortium owns and operates in south-eastern Ecuador.

The first contract is for an assessment of the water treatment plant and a water management plan that is adaptive over the life of the mine based on water flow and quality that will be monitored as part of the plan.

Added to this is a second contract to provide technical support for implementing immediate improvements in the engineering design and operation of the existing water treatment facility to increase its robustness and reduce both project risks and long-term operating costs, BQE said.

Qiaofeng Xu, the Project Director for ECSA, said: “We selected BQE Water for their unique technical expertise, their successful track record in the design and operation of large water treatment plants for major Chinese mining producers, and for their ability to support project execution utilising personnel from their South American, China and Canadian offices.”

Songlin Ye, Vice President for Asia at BQE Water, said: “Our ability to do business with large Chinese metal producers and the success of our water treatment operations in China were instrumental in securing these new contracts. The El Mirador project is significant for BQE Water as it showcases our unique strength to be a trusted water services provider for mining projects with Chinese interests at a time when Chinese investment in global mining projects can be expected to grow.”

Oscar Lopez, General Manager for Latin America at BQE Water, said the El Mirador project represents the first large mining project where the company will be the technical lead for the overall site water management plan rather than focus only on water treatment.

“And, with the long time horizon for water treatment at El Mirador, the current contracts may provide an opportunity for further cooperation between our two companies to support EcuaCorriente to reduce life cycle costs and conduct mining operations in an environmentally friendly manner at El Mirador,” Lopez said.

The El Mirador mine, owned by a consortium consisting of China Railway Construction Corporation and Tonglin Nonferrous Metals Group, is a large copper-gold porphyry project that was brought into production in 2019. It is expected to produce an average over 200 MIb (90,718 t) of copper and 60,000 oz of gold annually for the next 30 years.

The project site is located in a net positive water balance environment and will require ECSA to treat and discharge mine water into the environment throughout the project life, BQE said. “As production ramps-up and the mine footprint increases, both the volume of water requiring treatment and the water composition will change.”

BQE Water has been awarded its second SART plant contract in China, with Zhaojin Mining Industry Co signing up the mine wastewater and metallurgical bleed streams specialist to construct and operate the facility at a gold metallurgical operation, in Shandong Province.

The contract structure for Zhaojin, a state-owned company that is one of the largest gold smelters in China, is similar to the sulphidisation, acidification, recycling and thickening (SART) contract signed earlier this year with Shandong Zhongkuang Group Co, BQE said.

It consists of two project phases, with the first phase including initial engineering design, procurement, construction and plant commissioning. This will be followed by a second phase for onsite operations support services for an initial period of five years with BQE Water being paid a quarterly service fee based on plant performance.

BQE’s SART process enables cyanide consumed by base metals to be recovered and recycled, lowering the cost of gold extraction and reducing the environmental footprint of gold mining projects, the company says.

David Kratochvil, President & CEO of BQE Water, said: “The two back-to-back multimillion dollar SART contracts with recurring revenues from ongoing plant operations will allow us to expand our China office and develop a comprehensive platform for delivering our expertise in one of the most active metals extraction, smelting and refining markets globally.

“We are also appreciative of research and development funding and advisory services from the National Research Council of Canada Industrial Research Assistance Program (NRC IRAP).”

Songlin Ye, Vice President for Asia at BQE Water, added: “Our partnership with MWT Water Treatment Project Limited Co has allowed us to establish a commercial framework built on our combined core-competencies. Together these capabilities are highly suitable to the mining market conditions and requirements in China and will support BQE Water in the acquisition of additional contracts from the deployment of our know-how.”

BQE Water says it has been awarded its first contract to deliver a sulphidisation, acidification, recycling and thickening (SART) plant in China.

The contract, at a gold metallurgical facility owned and operated by Shandong Zhongkuang Group Co in eastern China, was awarded following the positive outcome of the engineering feasibility study and on-site testing completed by BQE Water earlier in the year, the company said.

The contract consists of two project phases. In the first phase, BQE Water will provide all aspects of the plant design, engineering support during procurement and construction, and plant commissioning, it said. This initial phase is to be completed within the next 12 months.

In the second phase, BQE Water will provide ongoing operations support services for a period of five years and will be paid a quarterly service fee based on plant performance.

David Kratochvil, President & CEO of BQE Water, said: “We are very excited about this project which enables BQE Water to demonstrate our leadership in SART technology in China and to execute the project using a business model that generates recurring revenues from technological know-how and services without the need for capital investment.

“I would also like to acknowledge the positive role that funding and advisory services from the National Research Council of Canada Industrial Research Assistance Program (NRC IRAP) has played in allowing us to accelerate research in clean Canadian technologies such as SART in China.”

Songlin Ye, Vice President for Asia at BQE Water, said: “The success of our operations at the Guoda gold smelter some 20 km away from the Zhongkuang site and our partnership with MWT Water Treatment Project Limited Co, were both instrumental in establishing the commercial framework for this project.

“SART implementation is the first step in the bigger picture of modernising cyanide management and waste treatment at the Zhongkuang metallurgical processing facility. The success of SART may open new opportunities to help us develop a long-term relationship with Zhongkuang.”

BQE Water calls itself a global leader in the SART process which enables cyanide consumed by base metals to be recovered and recycled, lowering the cost of gold extraction and reducing the environmental footprint of gold mining projects. The company also provides solutions to manage the by-products of cyanidation and cyanide destruction such as ammonia, nitrite and thiocyanate removal.

BQE Water has signed agreements with two of the top 10 gold producers in China to complete engineering feasibility studies to integrate the sulphidisation, acidification, recycling and thickening (SART) process and modernise cyanide destruction and residue management at existing operations in Shandong Province.

These studies are being undertaken in response to advancing environmental regulations and to enable the processing of feedstock with elevated levels of cyanide soluble copper, BQE said.

The feasibility studies will see BQE Water, which focuses on management of mine wastewater and metallurgical bleed streams, complete metallurgical and wastewater treatability test work in China and develop a sufficient level of engineering to confirm overall project economics, construction budget and schedule for possible implementation, the company said.

BQE Water calls itself a global leader in the SART process, which enables cyanide consumed by base metals to be recovered and recycled, lowering the cost of gold extraction and reducing the environmental footprint of gold mining projects.

David Kratochvil, President and CEO of BQE Water, said: “There is no question these new contracts were enabled by the success of the water treatment plant we designed and commissioned last year at the nearby Guoda gold smelter. That project has made all the major metallurgical operations in Shandong Province take notice of our capabilities.”

Shandong Province is home to some of China’s top gold producers. In the region alone where BQE Water’s new Guoda water treatment plant recently began operation, there are over 12 metallurgical plants that focus on gold extraction and refining, according to BQE.

Songlin Ye, Vice President for Asia at BQE Water, added: “If these new projects move forward to implementation, we will be able to leverage our operations base at Guoda and our partnership with MWT, the Beijing based company with construction capabilities we formed a joint venture with for the Guoda project, to build what would be the first SART application in China and provide ongoing operations services to ensure performance excellence.”

Cyanide regulations around the world are advancing and target not only residual cyanide contained in wastewater and tailings produced by mining and metallurgical operations but also place strict limits for cyanidation and cyanide destruction by-products such as ammonia, cyanate, thiocyanate and nitrite, according to BQE.

“The goal is to ensure all discharges are non-toxic and do not cause impacts to the receiving environment. As such, proper cyanide management is key to the permitting of new projects and securing a social licence for gold producers.”
