Mining company Alphamin Resources has completed C4 commissioning of its Bisie tin project processing plant in the DRC
The awarding of a C4 certificate indicates that a unit or the entire system can process the material. C4 involves feeding the system with material, checking instrumentation calibration, process flows and individual equipment throughput and building up to instantaneous design throughput.
C5 is the final stage of the commissioning process. This is achieved when the facility continuously runs at nameplate capacity for 48 hours.
According to a recent statement by Alphamin, the mine has taken longer than expected to attain C5, and the ramp up to nameplate capacity as aspects of the processing plant operations are refined and optimised.
Concentrate produced during commissioning and the plant ramp up, are being delivered to Gerald Metals in Kampala. Gerald Metals have taken delivery of 96 tonnes of concentrate. A further 192 tonnes are en route to Kampala from Logu, Alphamin’s marshalling yard for tin exports, where a further 240 tonnes are being cleared for export prior to departing for Kampala. Total production to date is 528 tonnes.
Sound Mining Solutions are nearing completion of the revised mine design. Once complete, the NI 43-101 will be updated.
