Recovery of Copper from Slow Cooled Ausmelt Furnace Slag

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. The factors which affected the copper recovery efficiency such as grinding fineness, pH value of flotation medium, different collectors and floating process were investigated.

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.

Effect of Cooling Rate and Slag Modification on the Copper

2020-7-31  Milling and froth flotation methods are quite common when dealing with slow-cooled slags. Before flotation, the slag needs to be cooled in a controlled manner. There are multiple options for this, such as natural cooling, casting mill cooling, water quenching, and slow cooling in a ladle [ 12 ].

Ferric leaching of copper slag flotation tailings

Copper can be recovered from the slags by froth flotation after cooling, crushing, and grinding. The obtained Cu-concentrate is sent to the pyrometallurgical process. If grinding is not fine enough for efficient flotation, copper is lost in tailings. In this paper, the ferric leaching of slag flotation

Laboratory batch flotation tests were conducted on copper converter slags to evaluate the relative merits of recovering copper from slow- cooled versus water-quenched slags. Three slags containing 1.6, 5.0, and 6.6 percent copper were used. More than 90 percent of the copper was recovered in a rougher concentrate leaving a 0.2- to 0.3- percent copper tailings when treating slow-cooled slag.
