Aug 27, 2021 It has been estimated that some 250 million tons of hazardous mining waste (such as lead mill waste tailings and chat) were produced in the Old Lead Belt from processing lead ore. Mining activities in St. Francois County have contaminated soil, sediment, surface water, and groundwater with elevated levels of heavy metals, primarily lead.

Thickeners or thickener plants--optimizing the performance

Dec 19, 2017 Optimizing the performance and cost of a thickener plant whether it is a self-contained plant that is separate from the main processing facility, or part of the mill is becoming a challenge as we increase water recovery with compact equipment, lower safety factors, and increasingly simplified testing campaigns.

Karara Mining to stack tailings high to keep costs, water

Apr 01, 2020 With environmental and cost factors in mind, Karara wanted to look at ways to have greater control over water assets on site. The ability to reuse and recycle water in the mining process would lead to substantial cost efficiencies by minimising the amount of makeup water needed for the mining operation, FLSmidth said.

The resulting tailings are like a moist soil and can be stacked in piles and compacted. However, filtered tailings can still lead to water contamination under certain circumstances.

The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold. The Miller process is rapid and simple, but it produces gold of only about 99.5 percent purity. The Wohlwill process increases purity to about 99.99 percent by electrolysis.
