Gold Leach Tank Aeration
The processing of low-grade gold ores is largely made possible through the use of the cyanide leaching process. The goal of any leaching process is to selectively bring a desired mineral into solution in order to efficiently separate it from the solid waste material. While many leaching processes typically use acid or alkali solutions at high ...

A new method for determination of preg-robbing in gold ores
Silicate minerals, especially clays have also been proposed as potential preg-robbers. It has been suggested that the positively charged edge surfaces of clay particles could attract negatively charged colloidal gold (Hausen and Bucknam, 1984).This can be seen in an electron micrograph presented by van Olphen (1977) that shows negative colloidal gold …

Abstract: Gold ores associated with carbonaceous matter present several difficulties in their extraction due to the ability of this matter to adsorb the aurocyanide complex from gold pregnant solutions, resulting in low extractions by direct cyanidation. This phenomenon is known as preg-robbing. In the present work, a process to effectively recover Au from a highly …
