plant design for leaching gold with thiourea
Discussion This work has adopted a factorial design approach to the assessment of thiourea leaching of the copper-gold ore. Eighteen experiments were used to create a model which describes the leaching of gold on the basis of selected factors. The study showed that acid washing is essential prior to thiourea leaching (Fig. 6).
Abstract The thiourea leaching of gold and silver from the gold bearing silicate ore of the Hishikari mine (Kagoshima, Japan) was studied. The apparent activation energy of the extraction of gold and silver was smaller than that of the reaction rate of thiourea . Read More → plant design for leaching gold with thiourea
Cyanide leaching has been the industry standard for gold processing for more than 100 years. During the cyanide leach process, a cyanide solution, or lixiviant, is percolated through ore contained in vats, columns or heaps. Gold is dissolved by the cyanide and then removed from the heap or columns.
An Overview of the EnviroLeach Gold Recovery Process agents have been identified that improve the gold leach kinetics as well as the stability of the gold that has leached into solution. These leach modifying additives are a unique and key component in the effectiveness of this process.

compared to sodium cyanide. The gold leaching reaction by thiourea and thiosulphate is very sensitive to p H and redox potential and both chemicals are intrinsically unstable decomposing readily to substances that are unable to leach gold. Complexing of gold by thio-compounds (p26). This means that process control is difficult and reagent recycling
