The depressed chalcopyrite was difficult to float and the recovery of copper was only 5.64% under the conditions: xanthate = 6.66 × 10 −5 mol/L, copper sulfate = 8.01 × 10 −5 mol/L, 2# oil = 10 mg/L and pH 10, while in the same conditions the recovery of copper from single mineral chalcopyrite exceeded 90%.

The Inco process can typically reduce cyanide concentrations to below 50 mg/L, while the Caro's acid process can reduce cyanide levels to between 10 and 50 mg/L, with the lower concentrations achievable in solution streams rather than slurries. Hydrogen peroxide and alkaline chlorination can also be used, although these are typically less common.

Summary. Gold cyanidation process refers to the method of extracting gold with cyanide as leaching solution. Since it was used in mines to extract gold and silver in 1887, it has a history of more than 200 years, and the technology is relatively mature. Cyanidation is still one of the main methods of gold production due to its high recovery ...
Cyanide Process – Extraction Of Gold Through Cyanidation . Gold is usually found in low concentration in the form of ore which is mined. Gold should be separated from other minerals present in the ore. As gold is insoluble, it should be separated from other minerals to make it soluble. Hence, sodium cyanide can be added, where cyanide ions ...
A few additional cyanidation tests were also conducted to verify the findings of the designed experiments. It was found that the overall extraction yield was varied from 67% to 90% depending on the operating conditions used in the sono-cyanidation tests (48 h). However, it was varied from 63% to 80% by same operating conditions used in the ...
1. Introduction. In the past 25 years, most of the development in the cyanidation of gold has occurred in response to the decreasing grade of deposits, the shift from surface mining to underground mining, the increasing complexity of treatment, and the concern for environmental constraints.Research has focused on the use of new equipment such as the …
The eight process requirements for a gold mine cyanidation plant are described below. 1. Inflate and add cyanide. Cyanide is added to the milled pulp to dissolve gold to form metal complexes. Oxygen is required during the gold leaching reaction, so in industrial production it is necessary to aerate the leaching tank.
Cyanidation, or the metallurgical process of extracting gold from ore with cyanide leaching agents, has long been a primary method of gold beneficiation.Widely used throughout the world, one incredible material helps to make gold recovery from a cyanide solution possible; with its ultra-porous structure, activated carbon is a powerful adsorbent used throughout a number of …
Globally, copper, silver, and gold orebody grades have been dropping, and the mineralogy surrounding them has become more diversified and complex. The cyanidation process for gold production has remained dominant for over 130 years because of its selectivity and feasibility in the mining industry. For this reason, the industry has been adjusting its …

Intensive Cyanidation Reactors (ICR) are used primarily for the gold leaching of high grade concentrates such as gravity concentrates. While applications exist for low volume high grade refractory gold ores, operational costs make intensive cyanidation reactors most viable on higher grade concentrates. Intensive cyanidation requires optimal ...
