Gold Recovery And How To Choose The Right Process

Ultra-fine gold particles can be trapped within the mineral matrix, even at extremely fine grind sizes. Three primary factors cause gold to be considered refractory. Each factor needs to be addressed with a different type of pre-treatment before gold can be recovered by conventional cyanidation. These factors are physical encapsulation
