Copper flotation from converter slag

Hydrophobicsurface of copper from converter slag in 2013710Flotation is one of the most effective way to recover useful metals in converter slag , . The converter slag contains 16% copper which is mainly in t

leaching of copper and zinc from copper converter leaching of converter slag flotation tailings from the svyatogor copper smeltery (sverdlovsk region, russia) by sulfuric acid solutions containing ferric ions was investigated.2recovery of copper and cobalt from converter slag 8200recovery of copper and cobalt from converter slag with a new flotation method using h4s 70 sulfuric acids [12, 13] with and without pressure [13], ferric chloride [8, 14, 15], ferric sulfate [7], cyanide, thiosulphate leaching [16], ferric sulfate and ammonia sulfate solutions [7, 12, 17, 18]. in this study, the flotation of converter slag wascomparative results of copper flotation from 201311260production of copper concentrate by flotation of smelter slag has started in 2001. flotation concentrate goes to the copepr smelter once more for production of copper cathodes and the rough flotation tailings go to the flotation tailing dump. copper recoveries in the flotation process of smelter slag reaches the value of about 45 50%. recovery of copper and cobalt from converter the recommended technological parameters for leaching of copper (the most important component) from converter slag flotation tailings are pulp density of 30% (w/v), ph recovery of cobalt from converter slag of chambishi 20119280converter slag and mainly in fayalite and magnetite as lattice substituents [6]. it is indicated that conventional techniques, such as slag cleaning, slow cooling of the slag followed by milling and flotation, are inappropriate for cobalt recovery from converter slag [78]. recently, hydrometallurgical processes for cobalt recovery fromoptimization of the flotation of copper smelter slags from 3260flotation tests which were performed on slag samples from three different sources (tsl furnace, copper converters, reverberatory furnace) to recover the copper minerals. a range of commercial flotation reagents including xanthates, dithiophosphates, mercaptobenzothiazole,

copper flotation from converter slag

recovery of metal values from copper slags by 2007210the recovery of copper and cobalt from ancient copper slags from the k252;re region of turkey was investigated. a fayalitictype of ancient copper slag containing 1.24% cu, 0.53% co and 53.16% fe were subjected to an experimental study. two different routes were followed to recover the metal values. the first route was roasting the slag with pyrite followed by leaching.recovery of copper from the slag of khatoonabad 2013650copper loss in the slag of khatoonabad flash smelting furnace is estimated to be about 13 %. at present, the electric slag cleaning furnace is used for the recovery of copper from slag. however, due to low recovery efficiency of electric furnace along with high consumption of electrical energy and water, selection of a method to enable minimum energy consumption and maximum recovery of hydrophobicsurface of copper from converter slag in 2013710flotation is one of the most effective way to recover useful metals in converter slag , . the converter slag contains 16% copper which is mainly in the form of copper sulfide, together with and the grade of metallic copper and copper oxide is less . however, converter slag in this research is quite distinct and contains 5.54% copper, in which, the grade of metallic copper is 2.01%.recovery of copper from copper slag and 2014980the experiments were performed using either reverberatory furnace slag or reverberatory furnace slag flotation tailings from the bor copper concentrator. the slag was sampled from the crushing line before entering the milling section of the concentrator, whereas the slag flotation tailings were sampled from the tailings disposal line. the slag sample was ground to pass through a 75 181;m sieve. flotation recovery of copper from the converter slag the flotation behaviour of a complex nonferrous slag, which contained tin, lead and copper, as well as willemite, galena and sphalerite, associated with oxidic and siliceous gangue, was investigated.the effect of cooling rate of slag from primary 2015450the content of copper in the flotation tailings directly depends on fragmentation rate (figure 1). expected content of copper in the flotation tailings, in the case of cooling in pits, is 0.50.9%, and in the case of cooling in pots, from 0.22 to 0.35% cu. fig. 1. the effect of fragmentation rate on the slag flotation enhancing the flotation recovery of copper minerals in 110table 1 shows that chalcocite is the main copper bearing mineral in the converter slag. in the tsl slag, copper is in the form of chalcocite, digenite and bornite. no copper containing minerals were detected in reverberatory slag, as it contains less than 1% copper.leaching of copper and zinc from copper converter 2012510the recommended technological parameters for leaching of copper (the most important component) from converter slag flotation tailings are pulp density of 30% (w/v), ph 1.5, temperature of 70 176;c, initial fe 3 + concentration of 15.7 g/l, no aeration, leaching for 1.5 h.
