202058Remediating mine tailings and recovering gold Orr said the patented Bacox bioleaching technology is applied to the processing of toxic arsenicladen mine tailings. An added benefit of bioleachingin addition to stabiliing arsenic and capturing heavy metalsis that it oxidies sulphides in mine tailings thereby eliminating a major
The ground ore is then floated to produce a gold rich copper concentrate for filtration and sale to overseas smelters. Flotation tailings are then leached for further gold recovery. The ore processing rate is approximately 35 million tonnes per annum. Typical head grade is approximately gram per tonne gold and per cent copper
200994Historic Gold Mine Tailings FAQ What are gold mine tailings Tailings are a byproduct of a gold mining process that was common in the late 1800s and early 1900s. Goldbearing rocks that also contain arsenic were crushed and spread over liquid mercury to remove the gold. The mercury was then evaporated leaving the gold
