The gold cyanidation extraction process is the main method for extracting gold from ores or concentrates, there are mainly three kind of ways to recover gold nowadays. There are heap leaching method, CIL and CIP method. Heap Leaching Heap leaching...
How is cyanide used in mining? A sodium cyanide solution is commonly used to leach gold from ore. There are two types of leaching: Heap leaching: In the open, cyanide solution is sprayed over huge heaps of crushed ore spread atop giant collection pads. The cyanide dissolves the gold from the ore into the solution as it trickles through the heap.

During the CIL process, gold is leached from the ore using an alkaline cyanide solution. The resulting gold cyanide complex ions are then concentrated and separated from the slurry by adsorbing onto activated carbon. Elution is the next step in the process, whereby the adsorption of the gold cyanide complex onto carbon is reversed.

Although many miners use mercury in artisanal and small-scale gold mining, it is possible to safely and economically recover gold without it. Mercury-free techniques are safer for miners, their families and local communities. They may also help miners market their gold at higher prices.
Gold recovery increase in CIL circuit. Various trials have shown the potential of PIONERA BioPolymer to increase metal recovery in leaching circuits. This is especially relevant in the CIL/CIP circuits used in gold processing. The benefit of PIONERA BioPolymer is also observed in the Merrill Crowe process.
For extracting gold from low-grade ores, heap leaching is practiced; huge heaps are sprayed with a dilute solution of sodium cyanide, and this percolates down through the piled ore, dissolving the gold. There are very well defined rules for the safe and responsible use of cyanide – as laid out in the International Cyanide Code. Gold refining
Cyanide can be used to extract gold, either in a controlled mill environment, or more crudely on rock piles in the open. Cyanide "vat leaching" mixes finely crushed ore with a cyanide salt in water. The cyanide binds to the gold ions, and makes them soluble in .
Alluvial gold mining, or river gold mining, is one of the most common and most accessible forms of gold mining in New Zealand. The government has set aside 16 areas for the general public to practice their gold mining skills without any need for licensing. Use your gold panning skills to discover the adventure that is alluvial gold mining.
The Gravity-Borax Method GBM is still unknown to most Artisanal and small-scale gold miners (ASGMs) worldwide as most still use mercury to extract gold. "Whole-ore amalgamation" is a technique that requires the use of 10–25 g of mercury to produce 1 g of gold.Within the last eight years, it has become evident that this technique is more widely used than earlier anticipated, and artisanal ...
