Carbon in pulp - Wikipedia

Carbon in pulp (CIP) is an extraction technique for recovery of gold which has been liberated into a cyanide solution as part of the gold cyanidation process. [1] Introduced in the early 1980s, Carbon in Pulp is regarded as a simple and cheap process.

Elution | Sodium Hydroxide | Elution

The Beisa elution process includes an acid-washing stage prior to elution. where the gold is deposited onto steel-wool cathodes which are calcined and smelted to form the conventional gold bar. This sequence takes 16 to 19 hours to complete.

Carbon Adsorption In Recovery Of Gold - Mine Engineer.Com

The gold is removed from the cathodes by either using a high pressure water spray, sometimes shaking the cathode, and in some cases, the stainless steel cathode is placed into a melting furnace and heated to 2,000 degrees F, to melt the gold from the cathode.

Gold extraction - Wikipedia

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.

During the elution of gold from activated carbon, the carbon undergoes chemical and mechanical attrition. Amount of the worn-out gold-containing carbon, which can be collected and processed at gold recovery plants, is evaluated at the rate of 20-25 kg per 1 ton of activated carbon treated during the elution.
