Aug 20, 2015 . New techniques for tailings treatment and sulfide ore recovery will see low-cost environmentally friendly heap leaching take another giant leap forward. . tailings and waste stockpiles. Currently, HL technology is successfully used to extract gold, silver, copper, nickel, uranium, and even iodine.
It is also the main reason of growing cost of copper production (Konieczny et al, 2009). Therefore, the standard methods of beneficiation appear to be insufficient and it became necessary to apply new. FLF technology to enhance the minerals liberation by chemical leaching with H2SO4 and to elevate flotation results indices.
