Cyanide Leaching Of Gold

The gold particle size has a tremendous effect on the time required for dissolution in a cyanide solution. Generally, the finer the gold, the quicker it will dissolve. A 45 micron particle of gold would dissolve in 10-13 hours, while a 150 micron particle might take from 20 to 44 hours to dissolve in the same solution. Oxygen plays an important role in the leaching of gold in a cyanide

Abstract Gold nanoparticles were synthesized by means of a reduction method based on the twophase method reported by Brust et al. [J. Chem. Soc. Chem. Commun., 801-802 (1994)]. The size of the particles was investigated as a function of the reduction rate of the gold ions. The reduction rate was controlled by changing the rate at which reducing agent was added to the gold salt solution.

PHASES OF A MINING PROJECT

The gold content of a good grade gold ore may be only a few one-hundredths of a percent. Therefore, the next step in mining is grinding (or milling) the ore and separating the relatively small quantities of metal from the non-metallic material of the ore in a process called 'beneficiation.' Milling is one of the most costly parts of beneficiation, and results in very fine particles that
