Gold

Our equipment is employed at various stages of the gold mining process:

Logwashers

The AggMax logwasher is employed when excavated or dredged material at the first stage of the gold mining process contains clay contamination.

The scrubbing action of the logwasher provides the attrition necessary to break down this clay contamination and remove it from the feed stream.

This ensures that the screening processes which follow can operate efficiently as the removal of the clays liberates fine material previously adhered to the larger mineral fraction.

Infinity screens

Our patented Infinity screening technology includes:

P-Line inclined sizing screens 

H-Line horizontal sizing screens 

D-Line dewatering screens 

F-Line fine material screens 

Counter Flow Classification Unit (CFCU)  

The CFCU is a means of density separation that allows for heavier gold particles to be removed from the lighter mineral fraction by means of a controlled upward flow of water.

EvoWash 

The EvoWash incorporates hydrocyclone technology and can be employed on gold mining operations to remove the very fine minus 75 micron / 200 mesh fraction from the feed stream and subsequently produce a 75 micron (200 mesh) to 6mm (1/4 inch) dewatered product.

This can then be stockpiled using our stacking systems and this process is used on operations using heap leaching as a means of gold recovery.

The stacked ore is treated with a dilute cyanide solution which serves to dissolve the gold. The solution leaches through the stack before being recovered at the base and subjected to further treatment to allow for recovery of the gold.

M-Series

The M-Series is a range of modular screening and classification plants with application in the processing of a wide range of mineral ores. The machine you receive is customized to the specific requirements of your gold mining project and will integrate with either the EvoWash fines processing system or CFCU.
