Leaching - Laboratory of Metallurgy - NTUA

Leaching - Laboratory of Metallurgy - NTUA

The leaching section is equipped to process different kind ores. Firstly, the ore is crushed and grinded in ball mill. The fine product is delivered to leaching lab, where the quartering, sieve analysis and leaching operation is carried out by different methods depending on mineralogy and specification of the ore, to extract valuable elements.

The primary leach vessels are linked to this satellite reactor, and the leaching materials circulate between the two. The SMRt gently scrubs the surface of the particles causing abrasion of passivating films and exposing reactive mineral surfaces. The abrasion of the particle surfaces is balanced to match the leach rate of the particles, so .

Leaching (chemistry) - Wikipedia

Leaching (chemistry) - Wikipedia

Leaching is the process of a solute becoming detached or extracted from its carrier substance by way of a solvent.. Leaching is a naturally occurring process which scientists have adapted for a variety of applications with a variety of methods. Specific extraction methods depend on the soluble characteristics relative to the sorbent material such as concentration, distribution, nature, and size.
