Harare-Caledonia Mining Corporation Plc has commissioned a new oxygen plant which is expected to improve metallurgical recover and reduce cyanide consumption at Blanket Mine (Blanket).
Based on test work conducted, the company anticipates that the plant will improve overall metallurgical recoveries at Blanket to approximately 94 percent.
Recoveries have averaged approximately 93 per cent in 2019.
“We are pleased to have successfully commissioned the new oxygen plant at Blanket and look forward to improved operating efficiencies as a result. This marks the latest in a series of investments to increase production and improve operating proficiency at Blanket as we continue our growth trajectory to 80,000 ounces per annum by 2022” CEO Steve Curtis said.
“The new oxygen plant will provide up to six tonnes of improved oxygen supply to the Blanket Carbonin-Leach plant which is expected to increase recoveries to approximately 94 per cent,” he added.
Curtis said the oxygen plant will result in slightly lower operating costs as cyanide consumption is expected to be reduced as a result of the improved oxygen supply.
The operating costs of the new oxygen plant, the mining company predicts, will be lower than those of the previous two tonne plant.
