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 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 .A process for extracting gold from a gold-bearing ore The process includes, first, providing a leaching liquor with thiosulfate anion and ethylenediamine Next, the leaching liquor is contacted with the gold-bearing ore to form a pregnant leach solution including gold dissolved from the gold-bearing ore Finally, at least part of the gold in.

How Is Gold Extracted From Gold Ore?

In all methods of gold ore refining, the ore is usually washed and filtered at the mine, then sent to the mill At the mill, the ore is ground into smaller particles with water, then ground again in a ball mill to further pulverize the oreMiners from Sonoran Mexico had a technique for pulverizing gold ore that required no water for the initial stages of gold processing Called the arrastre, this system consisted of an upright axle with large spok Horses or mules, hooked to the outside edges of the spokes, pulled them around and around Tied to the interior of the spokes were chunks of gold bearing quartz, which were dragged.
