/879/1/012021 This study aimed to investigate the applicability of coaloil gold agglomeration (CGA) assisted flotation to recover gold from a refractory ore. The ore with the grade of 25 g/t was tested with the CGAflotation process in six different size fractions from 38 to 300 urn using different collector types and dosages.

Free gold recovery by coaloil agglomeration by W. Kotze* and Petersen* Synopsis The gold mining industry has mainly relied upon the use of highly polluting chemicals, such as mercury and cyanide to recover gold from its ores. The Coal Gold Agglomeration (CGA) process was developed some years ago and has the advantage in that gold is

Froth flotation is one of the traditional methods for the recovery of gold like gravity, amalgamation, and leaching processes. The flotation process gets rather complicated when gold particles become finer due to their physicochemicomechanical relations (ElRahiem 2014).The coal gold agglomeration process (CGA) is considered an appropriate process for the problematic particles containing ...

In this process, fine raw coal, crushed below 10 cm, is comminuted in hammer crushers to below 250 μm and mixed with water to make a 50% by weight suspension; this is further ground below 15 μm and then diluted with water to 15% solids by weight.

The coaloil gold agglomeration (CGA) process is another approach to recover fine particles. It was developed by the British Petroleum (BP) research team in the early eighties and is based on the natural hydrophobicity of coal and gold compared with most gangue materials . It allows a selective recovery of hydrophobic gold particles attaching ...
