The waste’s recycling is generally done by pyrometallurgy process however since this method is not easily controlled it brings about fatal gases and causes the recovery of valuable low metals hydrometallurgy method is suggested Kamberovic et al Ever since a century ago cyanide process has been used to extract gold and other valuable metallic inerals nevertheless as cyanide causesGet Price
Hydrometallurgy originated in the 16th century but its principal development took place in the 20th century stimulated partly by the desire to extract gold from lowgrade ores The development of ion exchange solvent extraction and other processes has led to an extremely broad range of applications of hydrometallurgy now used to produce more than 70 metallic elementsGet Price
Gold has been valued for its beauty malleability and noncorrosive properties for millennia The most commonly used process is to extract gold by cyanide leaching which involves using substrates such as activated carbon for gold recovery Our goldselective ion exchange IX resins however are more versatile substrates than activated carbonGet Price
Gold extraction refers to the processes required to extract gold from its ores This may require a combination of comminution mineral processing hydrometallurgical and pyrometallurgical processes to be performed on the ore Gold mining from alluvium ores was once achieved by techniques associated with placer miningsuch as simple gold panningGet Price
