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 panning and sluicing, resulting in direct recovery of small gold nuggets and flakes. Placer m…read more
, beneficiation, or upgradation involves handling three primary types of ROM material, which have been blasted, fragmented, and brought out from an in situ position. These materials can be used directly or by simple or complex and even by applying extractive metallurgy like hydrometallurgical or pyrometallurgical methods.read more
Yet mining the ore is just one stage in a long and complex 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 the ore efficiently, safely and responsibly. On average, it takes between 10-20 years before a mine is even ready to …read more
, art of treating crude ores and products in order to separate the valuable minerals from the waste rock, or gangue.
