Monument famous, nonetheless, that flotation gold restoration was considerably inconsistent as a result of excessive clay content material of the freshly mined transition ore and the processing of stockpiled ore combined with oxides. Gold restoration averaged 61.4% for the 30-day interval, though each day charges of over 80% had been recorded.
To enhance restoration, the reagents are being optimized with specific consideration to the addition of soda ash for pH management, potassium amyl xanthate as a collector, and sodium hexametaphosphate as a slimes depressant. The problems with the flotation air blowers have been resolved.
Frequent failure of the strain filter cloths continues to be a problem, mentioned the corporate. Alternative filter material and filter plates have been ordered, however cleansing of the cloths and plates has improved total effectivity.
The primary part of mining the Buffalo Reef BRC2 and BRC3 pit is continuous. Each transition and recent ore have been delivered to the run-of-mine leach pad.
The Selinsing mine has confirmed and possible reserves of oxide, transition, and sulphide ores of 5.7 million tonnes grading 1.45 g/t gold and containing 267,000 oz.
