Leaching, by definition, is the process of extracting a substance from a solid material, after it has been in contact with a liquid. The substance being extracted from the solid does so by coming into solution, one which it is soluble in.

Chlorine Oxygen Leaching Process

Nickel, zinc, cobalt, and cadmium were recovered by taking a bleedstream (0.02 l/min) from the solvent extraction raffinate stream and precipitating all the metals by increasing the pH to 10.0 with caustic. Results obtained in the PDU are shown in table 11. After precipitation, all metal ions were below detectable limits in the filtrate. The metal hydroxide filtered slowly and had a high moisture content. …
