Investigation on the recovery of gold and silver from cyanide tailings using chlorination roasting process

Journal of Alloys and Compounds, 2018
Abstract In this work, a chlorination roasting method for the extraction of precious metals (gold and silver) from the cyanide tailings (CT) was investigated. The decomposition mechanism of the CaCl2 used as chloride agent was presented during the chlorination roasting.

Effect of various biogeochemical processes on mercury methylation in copper-zinc and gold mine tailings

2013
Mercury is a well known environmental pollutant. Anthropogenic sources include coal combustion, waste incineration and metal processing. In base metal mines, Hg is often left in the mining wastes (i.e., mine tailings). Once disposed of in open-air impoundments, these Hg-containing tailings can undergo various biogeochemical transformations, including ...

DEVELOPMENT OF A COMBINED GRAVITY-FLOTATION-SORPTION LEACHING FLOWSHEET FOR GOLD RECOVERY FROM OLD TAILINGS OF GOLD PROCESSING PLANTS

A combined flowsheet for reprocessing old (stockpiled) cyanidation tailings is proposed. It includes washing and classification, regrinding of the coarse fraction, centrifugal gravity concentration, sulphide flotation, intensive cyanidation of concentrates and resin-in-pulp leaching of flotation tailings.
