Preliminary Tests for Precious Metals Recovery from Sideritic Waste

Abstract:

Waste deposited in ponds can also contain precious metals, as trace elements. Preliminary studies have shown, by chemical analysis, the presence of gold and silver in waste steel. This paper presents some preliminary aspects of experimental work related to gold recovery opportunities from sideritic waste, Teliuc type - stored as a pond and future directions in research. There were two distinct phases considered: gravimetric concentration and removal of three layers from the experimental material, respectively, the treatment of the concentrate with “aqua regia”.
