Investigation of Alkaline Leaching Parameters on Stibnite

Jul 27, 2020 According to critical statistical studies, antimony is one of the rarest elements in the world, and global resources could be exhausted by 2050. In light of these observations, its extraction will be costly due to poor-quality ore, deep mining, remote locations, and high energy consumption. In the present study, an alkaline leaching process was carried out on stibnite concentrate to evaluate

How is Sodium Cyanide Consumed during Gold Cyanidation

Sodium cyanide is the most commonly used leaching chemical in gold extraction process. According to theoretical calculation, leaching 1 gram of gold only requires 0.5 grams of sodium cyanide. However, in most gold cyanidation plants, the consumption of cyanide is high, which is 50-100 times higher than the theoretical calculation.

Due to the low specific heat value of whole ore, it is generally necessary to add fuel to the reactor.
