SGS scientists developed and continue to improve these cost effective, time tested processes to extract gold from the pregnant cyanide solutions. Activated carbon effectively removes the gold from the cyanide, as the
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 is in high demand for products ranging from jewelry to electronics and medical devices. To extract gold from ore, mining companies typically use the sodium cyanide process, in which the gold is converted into a water soluble coordination complex and activated carbon is used to leach the gold from the slurry.
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 high lime solution prior to cyanidation.
AGR uses the Andrussow process to manufacture sodium cyanide solution. As the only sodium cyanide producer in Western Australia, we competitively supply sodium cyanide solution to gold mining operations in the states key gold producing regions. For technical advice on sodium cyanide solution, please contact your AGR representative.

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 do it with a highly toxic combination of cyanide salts.
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
A newly developed process gives gold mines an alternative to using cyanide for extracting gold from ore (Photo Shutterstock) In the gold mining process, the precious metal is often extracted from low grade ore in a technique known as gold cyanidation.
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.
How to recover gold from cyanide solution, learn more about how to recover gold from cyanide solution, e waste, chips, CPU, x ray films, photographic waste, aqua regia, cyanide solution, circuit boards and RAMS. Recovery methods extract or recycle of precious metal like Palladium, Silver and Gold.
CN Process CN process can be used for removing gold from gold plated electronic waste like connectors, fingers, jewellery and any other stuff which has gold polish on it. For the recovery of gold through this method one has to use commercial grade sodium CN (NaCN)

Cyanide process Cyanide process, , method of extracting silver and gold from their ores by dissolving them in a dilute solution of sodium cyanide or potassium cyanide. The process was invented in 1887 by the Scottish chemists John S. MacArthur, Robert W. Forrest, and William Forrest. The method includes three
Extraction of Gold by Cyanide Leaching. The process of cyanide leaching is mainly used where the earth has a high gold concentration making an industrial development worthwhile. For this process the gold bearing rock is crushed to sand and dust.
Click here to get an answer to your question Which process uses cyanide to extract gold?
It did extract gold as gold chloride. It was slow and cumbersome to utilize. Just a little later, around the turn of the century, it was discovered that gold could be dissolved in solutions of sodium cyanide.
Gold Extraction Process. Sod ium cyanide has been used in the extraction of gold from ore for over a century. Today it is still considered the most efficient extraction method with sodium cyanide used in the leaching process in most gold mining operations. Orica is one of the largest producers of sodium cyanide for the mining industry.

The cyanide paste acts as a buffer so that scrapings of copper do not contaminate the separated gold. The extraction is a dirty process, often doing environmental damage and causing lung damage and deafness to the workers, as well as the dangers of mercury and cyanide poisoning.
Extracting gold from ore is a poisonous business. The most common method is cyanide leaching, where cyanide salts in solution are used to suck the gold out from its ore. You get gold, but you also get highly toxic byproducts.
