BQE Water sorts SART plant for China’s Shandong Zhongkuang Group

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 moves a step closer to first SART application in China

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.

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.”
