Acid Leaching Copper Flotation Concentrate

As an alternative to Acid Leaching, Copper Chalcopyrite (CuFeS2) concentrates are processed traditionally by smelting, which results in sulfur dioxide (SO2) emissions. The development of a hydrometallurgical process for recovery of metals from concentrates of Cu ores offers industry a low-cost, low-pollution alternative to the traditional pyrometallurgical practices.

copper flotation and leaching - onsvertier.nl

Low copper extractions both from the slag and the slag flotation tailings indicate that sulphuric acid is not a suitable reagent for leaching these materials, at room temperature. This conclusion is in line with the study by Banza et al. (2002) where the leaching of copper smelter slag with

Selective Acid Leaching of Copper and Zinc from …

The goal of the present work was to develop hydrometallurgical method based on acid leaching, which makes it possible to perform selective extraction of non-ferrous metals from old flotation tailings. Leaching was performed with sulfuric acid solutions (from 0.5 to 10%) and distilled water. Leaching was carried out using percolators and bottle agitator.
