Metals
Dissolved metals in mine water are coming under increasing regulatory scrutiny. Regulations are evolving to include: stricter limits; constituents not previously regulated; and more mine sites subject to regulation.
Our Technology Solutions
Sulphate
Sulphate is a common by-product from mining activities. Coal and most metals are recovered from ore bodies containing sulphur based minerals that oxidize to sulphate when exposed to air.
Selenium
Growing awareness of the environmental impact of selenium has resulted in selenium removal becoming an important issue for mining operations.
Cyanide/SART
Cyanide leaching is widely used to extract gold from ore. This process is negatively impacted by the presence of cyanide-soluble base metals such as copper and zinc.
