Carbon leaching process is characterized by simultaneous gold leaching and adsorption stages with normal leaching segments of 6-10 segments In the leaching process ensure the fineness of grinding products - 200 mesh accounted for 85-95% the pulp concentration accounts for 40-45% then add a certain volume of CNLITE ECO gold leaching agent

06 05 2020Heap leaching is an industrial process for extracting precious metals and minerals by dissolving them from ore with liquids known as leaching solutions The process is commonly used to extract metals such as gold copper and uranium yellowcake in addition to several other minerals Heap leaching is usually carried out in the open and on slightly sloping ground covered with a watertight

In 1969 gold heap leaching began in Nevada (birth place of modern heap leaching) and in the middle of the 20 th century the United States Bureau of Mines began applying this technology Gold and silver heap leaching first began at Cortez in 1969 Currently 37 different heap leaching operations are active worldwide for the production of gold which is estimated to be around198 tons per year

Leaching often gold is the process of extracting a soluble constituent from a solid by means of a solvent In extractive metallurgy of gold it is the process of dissolving a certain mineral (or minerals) from an ore or a concentrate or dissolving certain constituents from materials such as a calcines mattes scrap alloys anodic slimes etc to achieve either one or two purposes
