Rougher flotation tests were conducted in Denver cells on a laboratory scale and metallurgical indicators such as copper recovery copper concentrate grade and concentration and enrichment ratios were compared with those obtained under similar conditions but using conventional collectors and frothers for the industrial flotation of copper

There are two distinct types of copper ore the sulfide ore and the oxide ore The sulfide ores are beneficiated in flotation cells ore thickener options are available to you There are 342 mining gold ore thickener suppliers mainly located in Asia is one of the manufacturer and supplier of high frequency screen coltan processing

The bulk rougher concentrate was upgraded in a cleaner circuit to reject the non sulphide gangue and then the resulting sulphide concentrate was separated by depressing the pyrite to produce two products copper and pyrite concentrates both having significant amounts of gold

BULK FLOTATION OF COMPLEX COPPER ORE

Copper processing is a complicated process that begins with mining of the ore less than 1 copper and ends with sheets of 9999 pure copper called cathodes which will ultimately be made into products for everyday most common types of ore copper oxide and copper sulfide undergo two different processes hydrometallurgy and pyrometallurgy respectively due to the different

The ganguerich underflow from the rougher cells is passed through a series of scavenger cells to collect any residual copper sulfide values not picked up by the rougher cells Dried flotation concentrates contain from 20 to 30 copper frequently 25–28 The concentration process recovers 80–90 of the metal content of the ore feed
