BQE Water deal for SART process implementation at Latin American gold mine

Posted on 15 Jan 2019

BQE Water Inc, a leader in the management of mine wastewater and metallurgical bleed streams, has entered into a services agreement with a wholly owned subsidiary of a Canadian mining company for the staged implementation of the SART process at an operating gold mine located in Latin America. The driver for this project is the possible extension of the mine life in a cost-effective way that simultaneously minimises the project’s environmental footprint.

In the first stage of the project, BQE Water will complete the SART plant engineering design for construction which will enable the client to confirm the construction budget and overall project economics. Subject to the client’s approval in Q2 2019, the project will proceed to implementation. At full capacity, the SART plant is expected to treat up to 600 m3/hr of leach solution, recycle approximately 6,700 metric tonnes of cyanide and recover approximately 3,400 metric tonnes of copper per year.

“We are excited about this project which in terms of its cyanide recycle and copper recovery capacities may become the largest application of SART in the industry to date,” said David Kratochvil, the President & CEO of BQE Water. “And with the need to achieve high plant availability and target metallurgical performance quickly following start-up and to maintain excellent SART performance throughout the project life, the client has also expressed interest in BQE Water’s services for ongoing plant operations once the plant is commissioned.”

Invented in the mid 1990s by Dr Chris Fleming at Lakefield Research, the SART (Sulphidisation-Acidification-Recycling-Thickening) process recovers copper from cyanide leach solution while allowing free cyanide to be recycled back to the leaching of precious metals. This lowers the cost of gold extraction and reduces the environmental footprint of gold mining projects. Fewer than ten industrial scale SART plants have been built and operated globally.

BQE states: “SART represents a natural extension of our core know-how in sulphidisation of waste streams produced by mining and metallurgical processing. Over the last two decades, BQE Water has designed, built and operated fifteen sulphidisation plants and applied its know-how to four large scale SART plants. Being involved in SART operations has enabled us to improve plant designs and ensure our SART projects reach and maintain target safety, mechanical, metallurgical and environmental performance. This helps our clients reduce the costs and risks of implementing SART. Recognised as a leader in SART, our project pipeline current includes six new SART projects in different stages of development globally.”

BQE Water is a service provider specializing in water treatment and management for metals mining, smelting and refining. “We are helping to transform the way the industry thinks about water in the context of natural resource projects by offering services and expertise which enables more sustainable water management practices and improved overall project performance at reduced risks. BQE Water invests in innovation and has developed unique intellectual property through the commercialisation of several new technologies at mine sites around the world for organizations including Glencore, Jiangxi Copper, Freeport-McMoRan and the US EPA.
