Effect of Copper and Iron Ions on the Sulphidizing ...

The Ruolanda slag is mainly composed of matte [ 5, 6 ], along with a small amount of copper oxide, copper, and traces of diffluent copper salts. The main constituents that need to be recycled are matte, copper oxide, and copper, and the most commonly used technique for the recycling is flotation [ 7

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.

Flotation of copper sulphide from copper smelter slag ...

Correlated the slag mineralogy with flotation performance of copper sulphide. The role of single collectors and collector mixture were evaluated in terms of copper grade and recovery. Examined the flotation results to investigate that whether there was synergistic effect arising from mixing collectors.

The proposed process involves the recovery of iron via magnetic separation from flotation tailings after recovering copper from CEFS by flotation. 72.79% of copper and 20.41% of iron were recycled from CEFS where the grades of copper and iron concentrate were 19.86% and 50.69%, respectively. This is a significant finding.

RECOVERY OF COPPER FROM COPPER SLAG AND COPPER SLAG FLOTATION ...

Copper extraction from the slag was typically found to be twice as high as that from the slag flotation tailings. Hydrogen peroxide was determined to be the best lixiviant. Thus, copper and iron extractions were 63.4% and 48.6%, respectively, when leaching the slag with 3 M H. 2.
