2015/11/04· Liberated grains of galena are about 15% covered into the copper rougher concentrate. Almost all of the remaining liberated galena is recovered in the copper scavenger concentrate. The recovery of liberated grains of sphalerite into the rougher and scavenger concentrate increases linearly with flotation …
2018/01/16· Fig. 1 shows the rougher flotation in a certain copper flotation site. During the whole flotation process, rougher is the first step of screening after ore is ground, mixed with water and classified. The products from rougher include theCited by: 11
2011/11/01· Cumulative copper recovery as a function of grade of copper concentrates obtained at different times by rougher flotation of a copper sulphide ore at pH 10.5 with biosolids, a salt of humic acids, and a mixture of conventionaln ⩾ 5).Cited by: 13
In the quest of new, less hazardous, and more ambient-friendly froth flotation reagents, the use of biosolids or humic acids as both collector and frother for the concentration of copper sulphide ores was investigated. Rougher flotation
2016/05/16· After the rougher flotation concentrate is reground it is cleaned twice in additional “Free-Flow” Flotation Machines with the recleaned concentrate going to final concentrate filtration or, as the metallurgy dictates, to a copper-moly separation circuit.
2020/07/26· The rougher flotation behavior of a sulfidized copper ore was studied by a series of batch flotation experiments. Response surface modeling ba sed on central composite design was applied to
Flotation experiments were conducted in a Denver type agitated flotation cell at the rougher stage. The experimental results showed that increasing the pH (from 8 to 10) at low agitation rate (1000 rpm) enhanced the recovery from 80.36% to 85.22%, while at high agitation rate (1200 rpm), a slight declination occurred in the recovery.Cited by: 6
the rougher/scavenger flotation circuit consistently recovers 91% of the total copper sulphide minerals, with the greatest loss typically being from the >75µm and <7µm size fraction. the enrichment ratio on the rougher/scavenger
Acopper rougher concentrate containing 10,0percent copper and 20,0per cent lead had been planned, but, during this initial period, the rougher concentrate averaged 12,7percent copper and31,4percentlead.A profile ofcopper and lead contents down the rougher bank showed noselectivity between copper reporting in thefirstrougher cellsandlead inthe rougher scavenger cellsaswouldnormally beexpected.
