Copper Recovery from Reverberatory Slag

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

Recovery of Copper from Copper Slag by Hydrometallurgy

In this research, the recovery of copper from copper slag is investigated using hydrometallurgy method. Slag samples were taken from Al-Shaheed State Company. The results of the chemical analysis showed that the slag contained 11.4% of copper. The recovery process included two stages; the first stage is leaching using diluted sulfuric acid.

A study on copper recovery from the slag of Outokumpu

Therefore, the recovery of the copper from this slag has a practical importance and heavily influences the operational costs. A part of the copper in the slag is in form of fine inclusions suspended in the slag; however, the majority of the copper is dissolved in it. The slag cleaning process is carried out in an electric furnace with coke and

Hydrometallurgical stepwise recovery of copper and zinc

Nov 01, 2020· Table 2, Table 3 revealed that zinc and copper were mainly present in the forms of zinc oxide and zinc silicate and cuprous oxide and cupric oxide, respectively. The smelting slag sample was ground, mixed, dried, and sieved to obtain 65–75 μm particles for the leaching experiments. Ammonium chloride with a concentration of 99.2% and stronger ammonia water with a concentration of 28% were

US3666440A Method of recovering copper from slag

copper is recovered from copper-containing slag by putting the matte and slag in a molten state together in a slag treating furnace at a volume ration of more than 1:5, the melts in the furnace being maintained under agitation so that the slag and matte are in intimate contact so as to efficiently transfer copper from the slag to the matte.

Recovery of Copper from Slow Cooled Ausmelt Furnace Slag

Ausmelt furnace slag contains about 0.9% Cu (mass %). With increasing the amount of Ausmelt furnace slag, the recovery of copper from it will produce an enormous economic yield. The recovery of copper by floatation from slow cooled Ausmelt furnace slag was studied in this paper. The phases and composition of the slow cooled slag were analyzed.

EFFICIENCY OF COPPER RECOVERY FROM A SLAG IN THE

Copper is present in a smelting slag from Teniente Converter (TC) in the form of mecha-nically entrained matte inclusions and dissolved copper. Copper recovery from the slag requires magnetite reduction to liberate matte inclusions and create conditions for co-reduction of dissolved cuprous oxide. Efficiency of copper recovery from the slag in an
