Recovery of valuable metals from mining and mineral processing waste

Autor: Panayotova Marinela, Panayotov Vladko

Publikováno v: E3S Web of Conferences, Vol 211, p 02009 (2020)

Ammonia-thiosulfate-copper leaching, aided by a direct current electrochemical impact, is proposed to extract gold (Au), silver (Ag) and copper (Cu) from old flotation tailings mixed with waste rock. Over 80 % of Au available in the waste material an
