200841 · In the present work a pressure oxidative acid leaching was used to clean up a waste smelter slag with low base metal contents of ∼1 Ni and Cu ∼ Co from a nickel/cobalt smelter and economically recover the base metals at mild conditions with lower oxygen overpressure and
The resulting waste materials are slags which may still contain valuable metal contents of up to or above . These contents are close to the cutoff grades of some nickelcop percobalt deposits. The methods that are used to recover copper from slags comprise in general further pyro metallurgical treatment often after enrichment by flotation.

3. Case Study Gold Smelter A gold smelter in the Shandong Province of China produces an acidic wastewater stream with a similar chemical nature to the acid mine drainage at the Dexing and Yinshan Mines in Jiangxi Province. The acidic stream contains valuable dissolved metals including copper zinc nickel and cobalt.

· A large amount of hot filter cake (HFC) is annually generated in Iranian zinc plants. It contains 1 zinc 16–30 manganese 5–25 calcium and 1– cobalt. Usually zinc is selectively leached by an alkaline medium and its residue is known as alkaline leached HFC (ALHFC). In the present study the possibility of cobalt extraction from ALHFC was investigated using a creative
202065 · Basic to any consideration of matte refining are the contents of iron and sulphur. In general matte will have much loss iron and much less sulphur than concentrate for an equivalent weight of nickel copper or cobalt. The process of smelting to produce matte rejects a large proportion of the iron and the sulphur associated with it.
201061 · Slag also contains base metals such as cobalt nickel copper and zinc that eventually contaminate the environment (Parsons et al. 2001). Considering the environment and the economic effect of pollution it is critical to find an effective and economical way to recover these valuable metals and to dispose of the waste slag.

The smelter also extracts zinc from various residual materials to produce zinc clinker which is a secondary raw material containing primarily zinc oxide as well as iron and lead that is sent to Odda for further refining. Odda has processed Rönnskär s zinc clinker since the 1970s.
This paper reports on the recovery of zinc cobalt and manganese by twostep leaching of zincplants purification residue with sulfuric acid. The residue hot filter press cake (HFC) contains 14 ZnO Co3O4 and MnO. Effects of different parameters are determined and used to optimize the process.
