Gold-miner Simmer & Jack (Simmers) has identified 15 initial targets as having potential for heap-leach recovery, following a comprehensive drill programme, the company said last week.
Simmers announced earlier this year that it izenith crusher spare parts in hydntended pursuing surface mining at its Mpumalanga operations. “The aim of the Mpumalanga exploration programme has been to mobile rock crusher in europedefine heap leach targets in the near surface oxide zones and define the deeper feeder systems of the surface gold occurrences,” CEO Glime scale plant in indiaordon Miller said in an emailed statement.
The targets include one 300 000 t sand dump at Elandsdrift, which will serve as a test heap leach pad, eight targets close to the metallurgical plant at TGME, termed DG 1 to DG8, and six targets in the vicinity of Frankfort mine, known as the Molototse Valley Exploration Project, where Carlin-type deposits have been found.
The company’s pilot heap leach pad at Elandsdrift, which was built to test the process using 300 000 t sand tailings, was ahead of schedule.
“Elandsdrift is our guinea pig in terms of heap-leaching and the sand dump is currently being loaded onto the pad. All that is needed in order to produce the first gold is for the carbon-in-solution (CIS) plant to be completed. This is expected to take place in the June quarter,” said Miller.
The CIS plant extracts the gold from the leach solution, capturing it onto carbon, which is then eluted and smelted at TGME’s metallurgical plant.
