Mine Tailings Waste Leaching Groundwater Contamination

16/06/2017  Data available from the literature reflect that metal-ore tailings are highly enriched in their metal content. Due to crushing and grinding of ore for milling purposes, the tailings also consist of small sized particles. On this basis, the character of tailings favors the rapid leaching

Leaching copper tailings

the method of testing a gold ore for treatment with a cyanide solution. This is the method that was used in this case for testing the possibility of leaching the copper tailings. The ore used,was a low grade copper tailing. The are is highly si1icous, which fact is favorable to leaching, as the Si02 does not interfere with the re­ actions between the copper in the ore and the solution.

(Bio)leaching Behavior of Chromite Tailings

In other words, Cr(VI) is potentially produced in the chromite deposit, and if it is not removed during the chromite beneficiation process, it can be still present in the concentrated ore and tailings. However, given the Cr release during leaching experiments with concentrated ore, in the tailings, chromite does not seem to be the main source of Cr(VI). Consequently, Cr(VI) leached from the tailings is coming
