Gold ore CIL production line and process flow solution

Gold Ore Carbon Immersion Leaching (CIL) Production Line and High Grade Gold Ore or Gold Ore Leaching Process Containing Accompanying Silver and Copper Technology Details

I. Overview of gold CIL process

Gold CIL process is an advanced gold extraction technology that synchronizes cyanide leaching with activated carbon adsorption. The CIL production line and process flow solution for gold mine significantly improves the gold recovery rate and reduces the production cost by simultaneous dissolution and adsorption of gold in the leaching tank, which is especially suitable for the development of high-grade gold ore and gold ore resources containing associated silver and copper.
