Activated carbon for gold extraction, selecting high-quality coconut and nutshell as raw material, is produced by physical method of high temperature steam activation, having uniform particle, strong adsorption ability and high mechanical strength.
It is mainly applied in modern Gold-mining Industry, especially in noble metal separation and extraction processes of gold-metallurgy industry by heap leaching or carbon-in-pulp process.
