How Gold Is Mined Gold Mining Process World Gold Council
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.
Tellurium was discovered by Franz Joseph Mller von Reichenstein, a Romanian mining official, in 1782. Reichenstein was the chief inspector of all mines, smelters and saltworks in Transylvania. He also had an interest in chemistry and extracted a new metal from an ore of gold, known as aurum album, which he believed was antinomy .
Then they mined back into the "vein" of gold ore, sometimes finding much more. When they dug the prospector became a miner. Although the mountains surrounding Pagosa Country were rich in gold the immediate area had no big gold finds or mines.

Ore minerals found within the mine include pyrite, chalcopyrite and minor suphides, tellurides of silver, mercury, lead, gold and native gold. The ore is generally difficult to melt. The deportment of gold is approximately 30% native gold, 25% telluride gold, 35% gold included in pyrite and 10% extremely fine almost invisible gold within pyrite.
Sulfide ores, and pyrites in particular, have caused and continue to cause difficulty in recovering the gold values from these ores. In most instances, visible gold can not be seen under microscopic examination of pyrite gold ores.
