What is agitation leaching?

Agitation leaching is a chemical process where in the soil that is to be mixed or slurried is kept in contact for a certain period of time with fluid to be extracted. What is the process of leaching? Leaching is the process of a solute becoming detached or extracted from its carrier substance by way of a solvent.

Jan 12, 2022 However, it is reported that the leaching efficiency of Cu from the speiss in H 2 SO 4 media is decreased due to the increased amount of Sb in the speiss caused by the co-treatment of various secondary resources during the TSL process. The solubility of Sb in H 2 SO 4 is low, which hinders the leaching of Cu.
