Leaching - Mining Fundamentals

Leaching is a chemical process in mining for extracting valuable minerals from the ore. Leaching also takes place in nature where the rocks are dissolved by water. Post leaching, the rocks areleft with smaller proportion of minerals that they originally contained.

What is leaching? | National Critical Zone Observatory

2016-7-1 · Leaching is not to be confused with the use of leeches as medicine. The word “leaching” is believed to have been derived from either late Middle English “leche” or Old English “leccan” meaning to moisten and to allow leaking. Currently, leaching primarily describes the process of water carrying soluble substances or small particles through soil or rock.

THE ALBION LEACH REACTORTM - Albion Process

2017-12-21 · The Albion Process is a combination of ultrafine grinding and oxidative leaching at atmospheric pressure. The feed to the Albion Process is a concentrate containing base or precious metals, and the Albion Process is used to oxidise the sulphide minerals in the concentrate and liberate these metals for recovery by conventional means.
