Scale, grades, processing costs, open pit vs underground. The interesting aspect of the AISC metric is the number of factors that feed into the final figure, and similar to any other sector costs, they can vary from month to month and year to year. In the case of gold stocks, better grades usually translate into lower cost mines.

one percent. The gold content of a good grade gold ore may be only a few one-hundredths of a percent. Therefore, the next step in mining is grinding (or milling) the ore and separating the relatively small quantities of metal from the non-metallic material of the ore in a process called ‘beneficiation.’ Milling is one of the most costly

Artisanal and Small-Scale Gold Mining Without Mercury
Gold miners have to smelt their gold in order to remove impurities resulting in pure gold. Most large scale gold miners send their ore to smelters with large equipment for the smelting process. Small scale miners still can do their own smelting using specialized kilns. Many people confuse gold smelting with melting.

This process is mostly used in large scale mining operations but has been increasingly adopted in small scale mining because of its high gold recovery rate and low cost. The best practices for chemical leaching are a combination of pre-concentration and mill leaching, as they lead to the least amount of waste, a short processing time for miners, and high gold recoveries.

Gypsum production process. Gypsum ore, from quarries and underground mines, is crushed and stockpiled near a plant. Asneeded, the stockpiled ore is further crushed and screened to about 50 millimeters (2 inches) in diameter.

Artisanal processing of alluvial gold deposits: Small scale artisanal mining (i.e., not using “modern” technology) has been estimated to account for 15 to 20% of the world’s non-fuel mineral production. The industry is highly labour intensive and employs 11.5 to 13 million people worldwide (Kafwembe and Veasey, 2001).
