Extraction of Gold using the Borax Process. The borax process is also an environmentally-friendly method of extracting gold. Here the gold-bearing rock material is placed in a melting crucible and then borax (sodium borate) is added. The borax sinks the melting point of the ore mixture and makes the molten mass fluid.

RECOVERY OF SILVER, GOLD, AND LEAD FROM A COMPLEX SULFIDE ORE USING FERRIC CHLORIDE, THIOUREA, AND BRINE LEACH SOLUTIONS By R. G. Sandberg 1 and J. L. Huiatt 2 ABSTRACT The Bureau of Mines investigated a hydrometallurgical procedure to re cover gold, silver, and byproduct lead from a complex lead-zinc sulfide ore.
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.
Comment (Deposit) Gold Mountain Au-Ag mineralization and Exploration Potential Previous drilling has been skewed heavily toward the east flank of Gold Mountain in the vicinity of the Falcon pit. The Tonopah Divide mine was centered on the NW trending Divide fault at its point of intersection with the north-dipping Gold Zone fault system.
Placer Gold Deposits (Gold Dust, Flakes Nuggets in Streams and Creeks) Placer gold deposits start out as lode gold deposits in rock. After many, many years of being subjected to the elements of temperature, wind, water and time, gold-bearing rock can erode and break down. These broken-down pieces of ore are crumbled over time into smaller.
Controlling the checkpoint means controlling the extraction of gold in the area. Since 2008, when the assets of two foreign companies, Gold Reserve and Cristallex, were taken over by the government, the exploitation of the largest gold deposit in Venezuela has remained in the hands of this increasingly organized crime group.
