How Goldmining Operations Benefit From Heap Leaching

Jun 15 2021 The heap leaching technique was first used for precious metals recovery in 1969 at the Cortez gold mine where it proved highly-efficient at improving

Cyanide Use In Gold Mining Earthworks

Cyanide Use In Gold Mining Earthworks

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. The pad collects the now metal-impregnated solution which is stripped of gold and resprayed on the heap until the ore is depleted.

Apr 25 2018 Heap leaching is used to extract gold copper silver uranium and iodine. This method was first employed to extract copper at the Bluebird mine in the US in the early 1960s and then by several gold mines in the western parts of the US a few years later. Since then heap leaching has been adopted successfully by many mines across the world.

Alamos Gold Mulatos Mine Mexico

The Mulatos mine is a conventional open-pit heap-leach operation with gold recovered through a carbon-in-column circuit. Ore is sourced from a number of open pits within the Mulatos District providing stable low-cost gold production. These include the main Mulatos and Cerro Pelon open pits as well as existing stockpiles.

The gold mining sector is currently dominated by cyanide as the leading gold extraction agent. It is an effective and low-cost reagent but it is a toxic chemical that creates significant environmental risk for mine operators and local communities. It is increasingly opposed by many communities NGOs governments agencies and investors.

Cyanide Leaching Of Gold Mine

Cyanide Leaching Of Gold Mine

The cyanide solution strength is also important in leaching gold with the typical range of solution being in the 0.02 -0.05 NaCN. The gold particle size has a tremendous effect on the time required for dissolution in a cyanide solution. Generally the finer the gold the quicker it will dissolve. A 45 micron particle of gold would dissolve .

Gold Cyanidation

Gold Cyanidation

Heap leaching extracts less of the gold than processing the ore in a mill but is much cheaper. There are a few alternatives to cyanide for processing low-quality ores but none are employed very widely to date 1. These alternatives are either expensive also toxic less efficient or inadequately studied.
