Gold extraction refers to the processes required to extract gold from its 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 mining such as simple gold panning and sluicing, resulting in direct recovery of
Gold is then leached from the carbon particles by a strong solution of sodium cyanide and sodium hydroxide and it is recovered from solution by electrowinning directly onto steel wool or by the MerrillCrowe process. In the latter process the goldbearing solution is deoxygenated and passed through a filterpress where the gold is displaced from solution by reduction with zinc metal powder.
The Hishikari Mine is located in the northern part of Kagoshima Prefecture. It has produced tons (as of the end of March, 2020) of gold since production started. The Hishikari Mine boasts highgrade gold containing an average of 3040 grams of gold per 1 ton of ore (the average grade of the world''s major gold mines is approximately 5 grams).
The lifecycle of a gold mine. People in hard hats working underground is what often comes to mind when thinking about how gold is mined. 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

A slurry of ground ore, water and a weak cyanide solution is fed into large steel leach tanks where the gold and silver are dissolved. Following this leaching process the slurry passes through six adsorption tanks containing carbon granules which adsorb the gold and silver. This process removes 93% of the gold and 70% of the silver.

Each ton of ore that is hauled out of a good pit mine may contain about a tenth of an ounce of gold. With gold at, say, 900 an ounce, that makes a ton of ore worth 90, tops. Considering that the huge trucks used at some mines can hold up to 300 tons or more on each run, a truckload of ore coming out of the mine can be worth around 27,750.
