Cyanide's efficiency makes mining more wasteful. Because cyanide leaching is very efficient, it allows profitable mining of much lower ore grades. Mining lower grade ore requires the extraction and processing of much more ore to get the same amount of gold. Partially due to cyanide, modern mines are. much larger than before cyanide was used;
Leaching gold with a cyanide solution remains the most widely used hydrometallurgical process for the extraction of gold from ores and concentrates. Despite the difficulties and hazards of working with cyanide, no other process has yet been proven to be an economic viable alternative.
Gold Cyanide Solution (Leaching Gold With Cyanide) Since the 1890's, cyanide has been used to recover gold from gold bearing ores. And today, over 115 years later, most of the worlds gold is recovered with cyanide playing a large part in the beneficiation of the yellow precious metal.
Gold cyanidation (also known as the cyanide process or the MacArthur Forrest process) is a hydrometallurgical technique for extracting gold from low grade ore by converting the gold to a water soluble coordination complex. It is the most commonly used leaching process for gold extraction.
Extraction of gold using cyanide Gold is found in very low concentrations in the ore from which it is mined. To collect the gold from the ore it needs to be separated from the other minerals in the ore. To do this the gold needs to be made into a soluble form so that it can be separated from the other minerals as gold is insoluble.

Gold, precious forever but especially lately, is a tricky metal. Bound up in consumer electronics, jewelry and the ores that it comes from, gold is difficult to extract, and most modern processes
The chemistry of gold solvent extraction from cyanide solution using . The concept of amine basicity is discussed and used to explain the selective extraction of gold from alkaline cyanide solution.
One promising alternative to using cyanide in gold mines is the Haber Gold Process, a non toxic extraction system that tests have shown can result in more gold recovery over a
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 1025 g of mercury to produce 1 g of gold .

Gold extraction refers to the processes required to extract gold from its ores. This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.
Cyanide has been used in the mining industry for over a hundred years. In New Zealand, despite the lack of stringent environmental safeguards for historical mining operations, there are no long term adverse environmental effects from the use of cyanide in the mining industry.
Here I present an Process EXAMPLE of Gold Extraction Cyanide in which the cyanidation feed consists of a pyrite concentrate floated after the selective flotation of a copper gold concentrate. The pyrite concentrate is reground to 90% minus 325 mesh and aerated in a
