Complete dissolution of the base metals was seen using 3 M nitric acid at 30 °C and the selective separation of copper from this leach liquor was achieved by solvent extraction using ACORGA M5640 dissolved in kerosene. The residues from base-metal leaching were treated with a mixture of 3 M sulfuric acid and 3 M sodium bromide at 70 °C ...

This work investigated the separation of copper (Cu) and molybdenum (Mo) from bulk Cu–Mo concentrate using pressurized water leaching (PWL) and Hallimond tube flotation. The effects of pressure, temperature, stirring speed, and solid–liquid ratio on the dissolution efficiency of copper and molybdenum were investigated using PWL. The results showed that …

It is important for the reader to understand that solvent extraction is only one unit process in a series of unit processes needed to win metal from ore. For this reason solvent extraction must be compatible with, and complimentary to, the leaching process which precedes it and the final metal recovery process which follows (Figure 1).
