Biohydrometallurgical Percolation Processing of Old Pyrite Tailings of OJSC "Svyatogor" with the Subsequent Thiocarbamide Leaching of Residue with the Purpose to Recover Gold

Abstract
The approach for processing old pyrite tailings of OJSC "Svyatogor" by heap leaching with the subsequent thiocarbamide leaching of gold is considered.
Conditions of percolation leaching of pyrite tailings, which enable one to recover up to 70 % copper, up to 86 % zinc, and up to 47 % iron, are considered. The
questions of gold recovery from residues of percolation leaching are investigated. The recovery of gold at a level of 44 % is attained using thiocarbamide leaching.
Attained indices of recovery of gold determine the efficiency of applying the heap leaching technology to studied pyrite tails.
