PERTH (miningweekly.com) – Potash developer South Boulder Mines has started pilot testing of the process design of its Colluli project, in Eritrea, at the Saskatchewan Research Council, in Canada.
South Boulder MD Paul Donaldson said on Thursday that the pilot plant would use potassium-bearing salts from the Colluli resource.
“We are pleased that we have been able to develop the test programme and commence its execution well ahead of the prefeasibility study (PFS) completion. This will allow a seamless integration of the pilot plant data with the definitive feasibility study design and final costings,” said Donaldson.
He noted that given the process was relatively simple and had been commercially proven, the pilot plant was simply an exercise to ensure all of the plant equipment was correctly sized for the final process.
The PFS on the Colluli project was scheduled for completion in February next year.
