- Large Throughput C Gold Flotation Cell For Copper Mine
Apart from the entrainment of normal fine particles during flotation, clay minerals with a particle size normally smaller than 5 μm also undergo aggregation, generating aggregate structures which compound the entrainment problem. The aggregation behavior of clay minerals is attributed to their complex crystal structure, …

Following in-house research and successful pilot trials at Blackwater using Denver flotation cells, the first, large, froth flotation circuits were installed at the Blackwater mine in 1967. The Blackwater circuit used 75 m 3 (100 ft 3) Denver cells to process 0.5 mm × 0 raw fines. While this installation was successful, there was a …

Copper (or metal) recovery percentages of the flotation circuits of a copper mine/mill are extremely important. For example, it is estimated that for a plant processing 50,000 tonnes of ore containing 1% copper per day, increasing the copper recovery from 86 to 87% of that contained in the ore could increase revenues by approximately $4 million ...

1. Background. The application of flotation on a reasonable scale within the gold-mining industry commenced in the early 1930s following the introduction of water-soluble flotation collectors (specifically xanthates and dithiophosphate collectors) that allowed differential flotation of sulfide minerals (Weinig and Carpenter, 1937, Rabone, …
