Getting to know leaching – Chromic

03/10/2018  Most importantly, leaching is applied in the metals processing industry to remove the desired metals from their ores, which are usually formed by many unwanted components. Gold, for instance, is leached from its ore using an aqueous cyanide solution. Chromium (Cr), vanadium (V), molybdenum (Mo) and niobium (Nb) – the valuable metals for the CHROMIC project – need to be extracted by leaching

Leaching - Mining Fundamentals

Leaching is a chemical process in mining for extracting valuable minerals from ore. Leaching also takes place in nature, where the rocks are dissolved by water. Post leaching, the rocks are left with a smaller proportion of minerals than they originally contained. The leaching process in mining is carried out either as heap leaching or insitu leaching.

Also known as "wet gel leaching", this is the process of immersing the latex-coated formers into a bath or spray of water, to wash out excess additives from previous stages, such as coagulant. Chemical and protein content can be reduced at this stage. The effectiveness of the process is dependent on the temperature of the water, the duration of the process, and the rate of water exchange.
