Dec 01, 1978 Process., 5: 285--296. A compound with a UV absorption maximum at 348 nm was observed in Mount Isa copper flotation plant solution. This spectrum was similar to that of the product of reaction of xanthate and peroxide in dilute, alkaline aqueous solution. The compound was termed perxanthate (more correctly O -alkyl dithiomonoperoxycarbonate)

By the 1960s, Mount Isa was the hub of a lead, zinc, silver and copper supply network, including smelting, refining and recycling facilities in Europe. In 1970, MIM Holdings succeeded Mount Isa Mines but, while diversifying in the 1970s and 1980s, management seemingly neglected Mount Isa. Revitalisation started in the late 1980s

Jul 20, 2021 The flotation process has a relatively simple flow and has the strong adaptability to the change of ore grade. Application: The flotation process is generally used for copper-lead-zinc sulfide ores with simple composition, high raw ore grade, large difference in floatability of useful minerals and coarse disseminated particle size

Oct 25, 2014 The dosage of a collector is an important factor that determines the efficiency of a froth flotation process. The representative sample of the carbonatitic Palabora copper ore ground 45 % passing 75 m was froth-floated with sodium isobutyl xanthate (SIBX) collector at 60, 70, 80, 90 and 100 g/t dosages. The concentrates and tails were dried and analysed. The results obtained showed that

The greenish powder that remains once the water content of the froth has evaporated is copper concentrate. But it’s not pure copper yet, it’s a copper iron sulphide, made up of about 35 per cent pure copper. Copper concentrate is fed into the ISASMELT furnace, where it is heated to 1185 degrees Celsius. This process melts the c
