CONSEP ACACIA: THE FINEST IN LEACHING TECHNOLOGY

CONSEP ACACIA: THE FINEST IN LEACHING TECHNOLOGY. GCA has installed and commissioned three Consep Acacias in Africa, in as many months. The first Acacia found a home at Cata Mine, Tanzania, the second in Liberia and the third was installed in Burkina Faso, with an order for a fourth being placed for Burkina. This brings the total Consep Acacia ...

Consep Acacia - Consep - Engineering Innovation

The Consep Acacia is a complete process solution to maximise recovery of gold from gravity concentrates such as those generated from a Knelson Concentrator. The Consep Acacia typically achieves overall recoveries in excess of 95%, often over 98%. Most importantly the Consep Acacia maintains an unblemished installation success rate.

Gravity Leaching With the ConSep ACACIA Reactor -

The ConSep ACACIA Reactor is a device, which utilises a high intensity cyanidation process to achieve very high, usually near total, recovery of gold from gravity concentrates. The process utilises a fluidised bed and a chemical oxidant to enhance the gold dissolution kinetics to the point where the bulk of the dissolution occurs in a few hours. For convenience and security, most plants ...
