Concept for a Hydrometallurgical Processing of a Copper

2020-3-11  The aim of this process is to reduce the mass that has to be leached in the hydrometallurgical process. 5. The Inco process, shown in Fig. 1, starts with a combined drying and reduction step, which takes place at 1000 °C in a rotary kiln. After this step, the nodules are smelted between 1380–1420 °C and separated in a manganiferous slag and

2014-1-1  Copper processing involves two common flow sheets shown schematically in Figure 2.7.4 . The flow sheet that is typically employed at a mine site is the hydrometallurgical process that treats solution from heap leaching by SX and electrowinning. Between 20% and 30% of the world’s refined copper is produced by hydrometallurgical methods . The

Behavior of copper and lead during mineralurgical and

2021-2-13  Hydrometallurgical studies of flash smelting slag processing have shown that selective copper and lead extraction from this slag is possible. Leaching with a low concentration of citric acid solution, carried out for a short time at a low temperature, leads to an effective leaching of lead from the slag with a low copper leaching efficiency.

Treatment of raffinate generated via copper ore

2020-2-15  The raffinate generated during copper ore hydrometallurgical processing is difficult to be treated because it is strongly acidic, and has high concentrations of heavy metals (Iron, Zinc, Copper etc). In this study, a bipolar membrane electrodialysis (BMED) system was studied for treatment of this challenging stream because in which salts can be

Hydrometallurgical processing of impurity streams

Solubilizing copper at this early stage in the process provides a number of advantages over existing hydrometallurgical processes for processing flue dust. One advantage of solubilizing a large portion of copper at this early stage is that it reduces the need to remove cooper in downstream stages with expensive consumable reagents such as NaSH.
