[PDF] Copper extraction from copper smelter slag with ...
This work presents the study of copper extraction from smelter slag, which is subjected to sulphating. Sulphating of slag was performed by pyrite concentrate or flotation tailings at temperatures from 500 to 650°C, and the resulting calcine was leached with water. The results showed that maximum copper leaching (7073%) is obtained from calcine, obtained by two .

How to generate value from tailings with reprocessing to ...
· With advent of novel technologies, mining companies are now figuring out ways to extract valuable metals from tailings. In gold, copper sulfide and iron ore tailings, the potential of extracting minerals is an opportunity. Reprocessing tailings to collect the valuable minerals can be a costeffective approach compared to processing material.
The website focused at tailings related ...
The word tailings is sometimes applied to include coarse mine waste. For this website the term tailings refers to the slurry waste output from the processing plant. The properties of tailings are dependent on the ore body being mined, the grinding and processing circuits, the reagent properties and the thickening process prior to disposal.
Tackling tailings: extracting value from a liability to ...
· Final tailings dewatering – Through dewatering and dry stacking and production of cake with dry solids content of 80%, effectively eliminating the requirement for tailings dams; Mineral flexibility – CDE's systems can be applied in the processing of a variety of ores, including gold, copper, zinc, and iron ore.
Investigation of the possibility of copper recovery from ...
The average copper and iron recovery obtained was from 60% to 70% and from 2% to 3%, respectively. These results indie that the old flotation tailings pond represents an important source of secondary raw material for the extraction of copper and that it should be valorized rather than land reclamation. At the end of the paper, a mechanism of ...
LEACHING OF FLOTATION TAILINGS
Keywords: flotation tailings, leaching, copper 1. INTRODUCTION The offbalance resources present the environmental problem and potential resource for copper extraction. The most commonly used method in the world for copper valorization from offbalance mine resources is the hydrometallurgical process.
Copper Concentrates
Minerals are concentrated into a slurry that is about 15% copper. Waste slag is removed. Water is recycled. Tailings (leftover earth) containing copper oxide are routed to leaching tanks or are returned to the surrounding terrain. Once copper has been concentrated, it can be turned into pure copper hode in two different methods:
How to Recover Copper from Slag by Flotation
· However, recovery of copper was about 4 percent lower for the high copper slag (sample C) and 23 percent lower for the low copper slag (sample A). Flotation tailings from the quenched slags ranged from to percent; slowcooled slags gave tailings containing from only to percent copper with lowest analyses for 30minute grinds.
Xtract Resources sampling on copper tailings dams complete
· South Africa – Xtract Resources has completed Phase 1 of its drilling and sampling programme on the Carolusberg and O'Kiep sulphide copper tailings dams loed in the Northern Cape, close to the town of Springbok. Phase 1 of the project was undertaken to confirm the estimated grades, volume and recoveries of the copper and other associated base metals .
