Acid Leach Process

The figure shown below schematically describes Dynatec's Acid Matte Leach Process, which is used for the treatment of nickel-copper mattes which contain platinum group metals. Dynatec's hydrogen reduction process for the recovery of pure nickel powder is an alternative to the recovery of electrowon nickel cathode from the nickel sulphate solution. Dynatec's pressure hydrometallurgical processes are effective for treating or upgrading copper sulphide concentrates.

The flow-sheet below shows the unit operations used in the process. Additional information about the autoclave is available.
