Processing

 

The Bissa process flowsheet is a simple, robust Carbon-in-Leach (“CIL”) design, well suited to the treatment of free milling gold.

 

The process consists of primary crushing before feeding to a SAG/Ball («SAB») grinding circuit, classification of the ground slurry product, thickening, leaching and carbon adsorption for recovery of the soluble gold and silver. The loaded carbon will be eluted using the AARL process and the precious metals electrowon onto stainless steel wool cathodes. The tailings is then sent to a TSF storage facility and water recycled back to the process All of the plant and equipment at Bissa is state of the art and new.

 

Infrastructure

 

A well-established base camp is located to the immediate east of the Bissa process plant and includes accommodation for about 180 people. In addition an admin office, laboratory and workshop/warehouse have also been constructed together with a haul road system.The project operates on a fly-in fly-out basis. A water management system comprising several sediment and water storage dams and a propose built raw water dam (Tiben Dam) clarifiers have been constructed.
