White Pine reverberatory furnace slags contained economically recoverable amounts of copper for a variety of reasons. Among them: White Pine concentrates yield extremely high matte grades (65+% Cu) and viscous slags. The viscous slags hinder matte settling causing matte "prill" entrapment in the slag. White Pine's total refined copper output is accomplished through fire refining ...
The recovery of copper from reverberatory furnace slag utilizing flotation has been studied. The effective factors such as particle size, pH, the amount and type of collector and additives, and ...
Laboratory and pilot plant investigations have indicated that copper recoveries of 50% can be achieved with fine grinding and flotation of a copper reverberatory furnace slag. Microscopic and microprobe studies indicate that the recoverable copper is in the form of matte, chalcocite, and metallic copper; the percentage of copper in particles appearing to be copper-free was from 0.23 – 0.54% ...
flotation 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 loss in the slag of Khatoonabad flash smelting furnace is estimated to be about 1–3 %. 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 ...
The 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 .
Recovery of Copper from Reverberatory Copper Slag ... Slags are waste minerals produced during furnace smelting of minerals. The contained ... because copper slag has a bond work index of 22 kWh/t and is thus a very hard slag. The process also has reduced flotation recoveries and requires high flotation reagent consumption.
Abstract. Aiming at the recovery of copper from smelting slag, a flotation approach was studied. It was found that this slag composed of fine particles with complex association and distribution, in which bornite was the main copper-bearing mineral after a detailed mineralogy analysis via .
The recovery of copper from reverberatory furnace slag utilizing flotation has been studied. The effective factors such as particle size, pH, the amount and type of collector and additives, and flotation time were examined. The effect of cooling rate on flotation behavior of the slag was also studied.
