Namibia Custom Smelters (NCS) process a range of copper concentrates in their three furnaces, namely; top submerged lance, copper converter and reverberatory furnaces, in order to produce mattes and fayalitic slags. The copper content of the slags range between 0.8 to 5 wt. % and this is considered too high for disposal to the …

The recovery of copper from copper smelter slag utilizing flotation has been studied. A copper smelter slag from the Wang Jiaqiao smelter in Yunnan Province of china, containing 2.76% Cu, 44.41% ...

Copper slag flotation was studied on an industrial scale at a concentrator plant in the region of Atacama, Chile. This study consisted of the physical, chemical, and mineralogical characterization of the copper slag, along with preliminary flotation tests. This article focuses on industrial flotation, which consisted of two oneyear campaigns (2016 …

Flotation is extensively used to recover copper and other metals from smelter slags [35,36]. Flotation with xanthate ... to improve the recovery of copper from copper slag by flotation process ...

The flotation process involves the application of chemical reagents, such as xanthates, dithiophosphates, and hydroxamates, which are toxic and hazardous. …

The flotation stage was performed in a Denver D-12 cell. It was carried out under the following conditions: PSD from 60% to 80% under 200# (ASTM); pH = 8,0; 40 g/t of F-503 (collector) and 30 g/t of H-70 (froather). These operational conditions were suggested by the Process Engineering and Chemical Laboratory staff from the plant.

The froth flotation process is an established physical separation technique for the recovery of ... iron selectivity behaviour of copper smelter slag (CSS) flotation tailings (38.08% Fe, 0.35% Cu ...

Published 2017. Materials Science. Aiming at the recovery of copper from smelting slag, a flotation approach was studied. It was found that this slag composed of fine particles …

The flotation behavior, smelting process, various properties of jamesonite (Pb 4 FeSb 6 S 14) and application of its extraction products were introduced.Jamesonite, as a sulfide mineral with complex composition and structure, is mainly distributed in China. It is usually associated with other sulfides with similar properties. Although the mineral …

approximately 378 million tons of flotation tailings w ere generated during the process of froth flotation. According to. data provided by the management of th is copper mine, the average metal ...
