Recovery of copper from reverberatory furnace slag by

For separating copper from reverberatory slag with a copper content of about 1%, flotation was used, and in one stage flotation a recovery of 72% to a concentrate containing 12.6% copper was achieved.

The Extraction of Copper Chemistry LibreTexts

Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper. The ores typically contain low percentages of copper and have to be concentrated before refining (e.g., via froth flotation). Figure 1 Chalcopyrite extracted from Zacatecas, Mexico.

The Recovery of Copper from Smelting Slag by Flotation

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

12.3 Primary Copper Smelting

iron sulfide. Because copper has a higher affinity for sulfur than oxygen, the copper in the slag (as copper oxide) is converted to copper sulfide. The copper sulfide is removed and the remaining slag is discarded. Converting produces blister copper by eliminating the remaining iron and sulfur present in the matte.

Copper extraction

Slag is less dense than matte, so it forms a layer that floats on top of the matte. Copper can be lost from the matte in three ways as cuprous oxide (Cu 2 O) dissolved in the slag, as sulfide copper dissolved in the slag or as tiny droplets (or prills) of matte suspended in the slag.

Recovery of Copper from the Slag of Khatoonabad Flash

The purpose of this study was the recovery of copper from the slag of Khatoonabad Flash Smelting Furnace (FSF) (Kerman Province, Iran) using the flotation method. Flash smelting is an oxidizing process containing high grade copper matte. The copper content of FSF slag is relatively high, and must be recovered before disposing of the slag.

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 , 8 ].
