Recovery of Copper from Copper Slag and Copper Slag Flotation Tailings by Oxidative Leaching
Copper smelter slag and copper smelter slag flotation tailings were leached using sulphuric acid solutions, without or with the addition of either ferric sulphate or hydrogen peroxide. 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 ...
متن کاملApplication practice of BOF Slag tailings in steelmaking process
The present paper introduces the steel production and BOF slag processing techniques in Steelmaking Sector of Bayuquan Iron and Steel Subsidiary, Ansteel. The technology of slag tailings utilization has been developed under the consideration of the properties of slag tailing and the characteristics of slag forming in BOF steelmaking operation practice. The processing of the BOF slag includes ho...
متن کاملAssessment of the use of spent copper slag for land reclamation.
The shortage of waste landfill space for waste disposal and the high demand for fill materials for land reclamation projects in Singapore have prompted a study on the feasibility of using spent copper slag as fill material in land reclamation. The physical and geotechnical properties of the spent copper slag were first assessed by laboratory tests, including hydraulic conductivity and shear str...
متن کاملOvercoming bureaucratic obstacles to the re - use of metallurgical slag – A South African case study
Metallurgical slag, including ferrochrome slag is internationally recognized as suitable material for use in road construction and as aggregate for concrete (Rossouw et al. 1981, Lind et al. 2001). Contrary to international practice, metallurgical slag – including ferrochrome slagis classified as hazardous waste that must be de-listed before use in other applications (DWAF 1998). Having adopted...
متن کاملRational Utilization of Fine Unclassified Tailings and Activated Blast Furnace Slag with High Calcium
The utilization of cemented tailings/paste backfill (CPB) by the mining industry is becoming increasingly important. However, it has been difficult to analyze the economic usage of CPB for fine unclassified tailings. Therefore, the physical and chemical properties of fine unclassified tailings, sampled from the Sijiaying Mine, were first analyzed in this study. After this, active excitation of ...
