Minimise Carbon Loss

 

Our Technology

The Process

Carbgold’s Patented Process

Carbgold Australia Pty Ltd utilises a patented process to clean and recover gold-bearing activated carbon.

Benefits of the Process

Our process will result in a more efficient and profitable operation through:

  • Substantial reduction in gold lost in fines being pumped to tails
  • Substantial reduction from carbon lost from ‘grinding’
  • Reduced blinding of intertank screens, allowing increased throughput
  • Removal of unwanted and preg-robbing material
  • More efficient stripping operations with only clean and consistently sized carbon moving through your stripping/regeneration circuit
  • Allows the mine to decrease the stocks of new carbon held
  • The removal of sand and grit reducing carbon wearing and gold loss

Recovery Process

Pre-conditioning, incorporating:

  • Scalping @ + 12mm material
  • Scrubbing of material (pressure washing)
  • Scalping @ +6.0mm

Drying of material

Gravity separation, removing:

  • Sand and grit – to greatly reduce carbon ‘wearing’ and loss of gold and blinding of screens
  • Silica – redusing ‘gumming’ within your stripping circuit
  • Woodpulp
  • Plastic and rubber

The cleaned carbon will then be:

  • Sized to your requirements (generally 2mm RH & 1.5mm slot)
  • Product bagged and numbered (3 lines)
