chlorination of copper and nickel sulfide concentrates

a chlorination process for treating metal sulfide flotation concentrates is described. the process involves low temperature chlorination combined with sulfur chloride conversion and selective oxidation to produce nonferrous metal chlorides, elemental sulfur, and ferric oxide in a threestage fluidized bed reactor.inquire now

copper oresdanafloathome

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.inquire now

sodium hydrosulfide nashan alternative to sulfur

sodium hydrosulfide solution is an alternative product to sulfur from hydrogen sulfide. much hydrogen sulfide ends up on solid bed medias such as iron sponge or sulfatreat®. this is disposed of in landfills. these processes are justified in most cases. depending on your production rate of hydrogen sulfide, a claus unit may be just what you inquire now

copper sulfatecuso4pubchem

copper gluconate and copper sulfate were reported to be used as nutrients in milk products, processed fruit juices and drinks, soft candy, snack foods, beverages, chewing gum, and baby and infant formula. in addition, copper sulfate was reported to be used as a processing aid in alcoholic beverages.inquire now

role of sodium sulfidecopper lead & zinc ore flotation

sodium sulfide is one of the most widely used alkali metal sulfides in the flotation of copper, lead, and zinc minerals in their oxidized form. the sulfidization process, developed in the u.s.a. in 191520 for oxide copper minerals flotation, is especially suitable inquire now

copper production: how is copper made?the balance

the froth, which contains about 30% copper, 27% iron and 33% sulfur, is skimmed off and taken for roasting. if economical, lesser impurities that may be present in the ore, such as molybdenum, lead, gold, and silver, can also be processed and removed at this time through selective flotation.inquire now

lead and zincdepartment of energy

lead and zinc lead and zinc ores are usually found together with gold and silver. a leadzinc ore may alsosuch as zinc, silver, copper, and gold. lead is essentially a coproduct of zinc mining or a byproduct of copper and/or gold and silver mining.flotation to produce concentrates of 50 to 60 percent zinc. lead ore also requires inquire now

influence of sulfurcontaining ions on selective flotation

the selectivity is better than that achieved in fresh water, and the recovery of nickel into the copper concentrates is reduced by 57%, with a consequential increase in the copper: nickel ratio from 12.4 to 15.418.4. the index of selectivity is increased by 1416%.inquire now

copper production: how is copper made?the balance

if economical, lesser impurities that may be present in the ore, such as molybdenum, lead, gold, and silver, can also be processed and removed at this time through selective flotation. at temperatures between 9321292 ° f 500700 ° c, much of the sulfur content remaining is burned off as sulfide gas, resulting in a calcine mix of copper inquire now

treatment of mixed sulfide oxide ores of copper

while it might not be very difficult to coat pure copper silicate with sulfide and recover it in concentrated form by flotation, concentration of most of the silicate copper of the southwest would lead to nothing at all. the copper is in so dilute a solution that a bright blue color may mean a copper content no higher than 1 or 2 per cent.inquire now
