Gold Heap Leaching Process sand washing machine

By spraying leaching solution to the large piles the gold-containing solution is leached Then used the method of carbon adsorption zinc powder displacement device and so on to separate gold

The Metallurgy of Cyanide Gold Leaching An Introduction

At the end of the leach the loaded carbon is removed from the slurry and the adsorbed gold is stripped out at high temperature and pressure with sodium hydroxide and cyanide solutions to form a high value electrolyte solution

Carbon Adsorption In Recovery Of Gold Mine Engineer Com

The carbon in pulp method is only used where tank leaching is utilized for the recovery of gold from the ores and this is not the case in most large gold mines today since heap leaching is the lowest cost method for recovering gold from ores containing from a few grams to 5 or 6 grams per ton
