effective flotation collector reagent selection is dependent on the sulphide minerals present, their mineral associations in the ore, and circuit characteristics. because an ore typically has more than one copper sulphide mineral type, often a combination of sulphide flotation collectors is used to maximize metallurgical performance..flotation reagents chemical reagents mining reagents,company in brief. sellwell group flotation reagents factory is specialized in manufacturing multi-series of flotation reagents including xanthate, dithiophosphate, dithiocarbamate, aerofloat, sulfur, nitrogen, frothers, etc. last year our annual production capacity is over 30,000 mts and 45 percent of products have been exported to australia ...
the flotation process. until quite recently copper ore had to be hand-picked if the extraction of the metal was to be economical. in fact, in the last century, ores of 4 percent grade were regarded as almost valueless. today such ores which would be regarded as relatively rich in copper are scarce the great majority of mines contain the ....recovery of carbonate copper ore by means of flotation,6 - flotation plant bquipment. 7 - reagents and oils used in the flotation prooess. 8 - operation of the flotation plant. 9 - effeot of slimes on flotation. 10 - laboratory and test work in oonneotion with flo tation. 11 - tonnage and ooats. 12 - aonalusion..chapter 16 flotation of nickel and nickel copper ores,handbook of flotation reagents chemistry, theory and practice flotation of sulfide ores addressed to the researchers and plant metallurgists who employ flotation reagents, this text examines the theoretical aspects of flotation reagents as well as the practical aspects of using chemical reagents in operating plants.
