How Gold Is Mined | Gold Mining Process |

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 responsibly. On average, it takes between 10-20 years before a gold mine is

Small-scale mining of gold is responsible for 1/3 of the total mercury released into the environment, as mercury is used to separate gold from its ores. Acid mine drainage methods, and tailings pools, which hold mine waste products such as sediments and minerals, present further risks. The release of such waste has disastrous consequences, as exemplified by the collapse of the tailings dam of

How Gold Mining In Peru Is Poisoning The

The gold mining process in Peru involves the use of mercury to extract gold. After blasting away the top layers of soil by high pressured water at the mining site, the resultant slurry is mixed with mercury and squashed by foot in large oil drums to extract the precious metal. The entire process generates huge volumes of mercury waste that is then discarded irresponsibly into the environment
