Figure 4b shows metal recovery ratios as functions of slag basicity of 0.5, 1, 1.5, and 2. It can be seen that the metal recovery ratios of Fe, Mn, Cr and V sharply increased with the slag basicity increasing from 0.5 to 1.5, followed by a slight increase or staying nearly constant as the slag basicity was further increased to 2.0.

We describe the use of sulfiding agents to achieve a significant increase in the level of metal recovery during the smelting of copper concentrates and matte conversion. In the conversion process for copper and polymetallic mattes, the addition of sulfides produces (1) a remarkably low level of nonferrous metals remaining in converter …

A recovery ratio of 97.47% Cu in the copper phase was obtained at a lower temperature and shorter duration compared to the pyrometallurgy methods. Wang et al. [ 104, 105] also attempted to separate fine copper droplets from copper matte smelting slag by utilizing super-gravity.
Copper slag also contains zinc and lead [13]. To improve the economic benefits and reduce the serious damage of copper slag to the surrounding environment [14], it is essential to extract the valuable metals contained in copper slag. At present, the main industrial recovery method of copper from copper slag is the flotation method [15,16].
Compact, two-stage magnetic separation. With the STEINERT MRB you achieve high-value material extraction of ferromagnetic metals in the fine grain range. Our two-stage magnetic separator therefore combines a STEINERT MTP extracting magnetic drum with a STEINERT MSB traversing magnetic pulley. Whilst the former generates valuable scrap …
Copper slag is a metallurgical waste that is disposed by way of stockpiling at designated dump sites within a mining site. The observed depletion of high-grade iron ores in Botswana and the ...
A study of the recovery of copper, cobalt, nickel and zinc from copper converter slag by roasting with ferric sulphate is reported. Roasting of converter slag with ferric sulphate, followed by leaching with water, was carried out in order to bring the metal values into solution. For 500°C roasting temperature, 120 min roasting time and …
Slag cleaning can be divided into two types, first being the py- of the copper minerals can be enhanced by studying the mineralogy, rometallurgical reduction and settling of liquid slag, which is performed milling and liberation profile of the slags and the flotation reagent suite in slag-cleaning furnaces, and the second type being the ...

Recommended Processing Routes for the Recovery of Valuable Metals in the Slag A combination of mineralogical and chemical methods indicated that the historic slag from Tsumeb smelter contains extractable metals such as copper, zinc, lead and arsenic whose average compositions are 0.35% Cu, 5.5% Zn, 3% Pb, and 0.2% As, respectively.
The slag also contains high concentrations of valuable metals and metalloids such as copper, cobalt, zinc, calcium, aluminium, silver, magnesium, and lead. The variation in the chemical and mineralogical composition of copper slag is mainly influenced by the type of concentrate, type of fluxes, furnace type and cooling rates during and ...
