How Gold Is Mined Gold Mining Process World Gold CouncilHow gold is made history used parts procedure

Yet mining the ore is just one stage in a long and complex gold mining process Long before any gold can be extracted significant exploration and development needs to take place both to determine as accurately as possible the size of the deposit as well as how to extract and process the ore efficiently safely and responsiblyOnce extracted the gold is refined with one of four main processes floatation amalgamation cyanidation or carbon in pulp Each process relies on the initial grinding of the gold ore and more than one process may be used on the same batch of gold ore Mining
