The Recovery of Copper from Smelting Slag by Flotation

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 copperbearing mineral after a detailed mineralogy analysis via

possible option. The copper slag contains a high content of silica and iron. The solution final pH is the most important factor affecting the removal of iron and silica from the leach solution and the overall metal recovery. Fe removal from the leaching of copper slag is done by the formation of a metal hydroxide.

Flotation of copper sulphide from copper smelter slag

Flotation performances were increased effectively by the combination of collectors. The findings show that a higher copper recovery (84.82%) was obtained when using a 40:160 g/t mixture of sodium isopropyl xanthate (SIPX) with diethyl dithiophosphate compared to 78.11

Utilization of Flotation Wastes of Copper Slag as Raw

Copper slag wastes even if treated via processes such as flotation for metal recovery still contain heavy metals with hazardous properties posing environmental risks for disposal.

Utilization of flotation wastes of copper slag as raw

Copper slag wastes even if treated via processes such as flotation for metal recovery still contain heavy metals with hazardous properties posing environmental risks for disposal. This study reports the potential use of flotation waste of a copper slag (FWCS) as iron source in the production of Portland cement clinker.

Some properties of a typical copper slag are shown in Table I and it can be observed that aircooled copper slag has a black colour and glassy appearance. The specific gravity varies with iron content from 2.8 to 3.8. The unit weight of copper slag is somewhat higher than that of conventional aggregate. The absorption capacity of the

Utilization of flotation wastes of copper slag as raw

During smelting an oxiderich phase known as slag forms and is segregated from the coppermatte (sulphide) phase. The slag phase consists predominantly of FeO Fe 2 O 3 and SiO 2 with small amounts of A1 2 O 3 CaO and MgO as well as metals such as Cu Co and Ni in metallic or oxide/sulphide form [1] [2] [3].
