It is recommended to use heap leaching in processing of dumps of mineral products containing man-caused ferrum together with noble and/or non-ferrous metals. Using combination of these processes applying to the products of gold mining allows to rise gold extraction by more than 15 % and silver extraction, to utilize iron as scrap of green vitriol directed on neutralization of leached ore stack and excessive quantities of solutions with removed gold.
