Ore from the gold mine is first crushed in rod or ball mills. This process reduces the ore to a powdery substance. The gold is then extracted by amalgamation with mercury or by placer procedures. Approx. 70% is recovered at this point. The remainder is then dissolved in dilute solutions of sodium cyanide or calcium cyanide.
Pour the acid-and-bleach mixture into the plastic bowl with the ore grains and stir. Allow four hours for the gold to dissolve, stirring every 20 minutes. The chlorine reacts with the gold …
Extracting Gold HowStuffWorks. Leaching dissolves the gold out of the ore using a chemical solvent. The most common solvent is cyanide, which must be combined with oxygen in a process known as carbon-in-pulp. As the cyanide and oxygen react chemically, gold in the pulp dissolves. When workers introduce small carbon grains to the tank, the gold . get price

Cyanide leaching is one of the main methods to recover gold. It has the advantages of high recovery rate, fast speed, and strong adaptability to gold ore, and can produce gold locally, so it has been widely used. Cyanide leaching of gold can be divided into tank leaching (stirring leaching) and heap leaching (percolation leaching).
1 Use an ammonium thiosulfate solution which is recycled at a temperature of 15-25°C to process silver-gold ore. 2 The filtrate produced after dissolution is electrolytically extracted with a high alloy electrode at a current density of 200...250 A/m 2 until the electrolyte reaches a concentration of 5-15 ppm Au, 1-100 ppm Ag and 0.1-1.0 g/1 Cu.
This gold ore beneficiation process is to first use gravity separation to recover the coarse-grained gold in the ore, and then gravity separation of tailings is in the flotation process. The gold ore beneficiation process is suitable for processing single flotation processed ore, …
