Zinc Portable Photometer HI96731 Hanna Instruments

Chemistry of Process. The chemistry of zinc precipitation depends mainly on the fact that gold and silver metals are more noble than zinc. This means that they are more apt to reduce to their native states i.e., Au and Ag than remain in a gold or silver-cyanide complex. A generalized cementation reaction may be written as follows

Hydrochloric acid allowed the leaching up to 60 of tin and about 50 of lead, as well as the iron. Nitric acid was the most efficient leachant due to its oxidizing properties. Recoveries of 90 or more for copper, iron, nickel and zinc were achieved at the higher temperature. Lead was also dissolved up to 80, as well as silver more than 70.

The process design of gold leaching and carboninpulp

Leaching reagents in the form of cyanide and an oxidant such as air or oxygen are added after thickening. Leaching takes place in a series of agitated leach reactors or pachucas. Before leaching the pH of the pulp is normally adjusted to a value of around 9.511 to ensure minimum loss of cyanide as hydrogen cyanide.
