Tank leaching - BioMineWiki - Skellefteå
In a continuous stirred tank reactor (CSTR) series leaching is co-current, i.e. a pulp of ore/concentrate and leaching reagents are pumped into the first reactor and then allowed to overflow to the following tanks in the reactor series.

Tank leaching [ edit ] Stirred tank, also called agitation leaching, involves contacting material, which has usually undergone size reduction and classification, with leach solution in agitated tanks. The agitation can enhance reaction kinetics by enhancing mass transfer. Tanks are often configured as reactors in series.

The purpose of the present work was to investigate the effect of aeration, O 2, CO 2, agitation, various sulfur types and dosages and pulp density on the growth of Sulfobacillus thermosulfidooxidans and bioleaching efficiency of electronic scrap in stirred tank reactors. Sulfur bioavailability, metabolism, and oxidation degree were also evaluated.
Tank leaching - Wikipedia
Tank vs. vat leaching Factors. Tank leaching is usually differentiated from vat leaching on the following factors: In tank leaching the material is ground sufficiently fine to form a slurry or pulp, which can flow under gravity or when pumped. In vat leaching typically a coarser material is placed in the vat for leaching, this reduces the cost of size reduction;

Effect of Na-chloride on the bioleaching of a chalcopyrite ...
Chloride is known to enhance the stone leaching of chalcopyrite, but much of this effect has been demonstrated at elevated temperatures. This study was undertaken to test whether 100–200 mM Na-chloride enhances the stone and bacterial leaching of chalcopyrite in shake flasks and stirred tank bioreactor conditions at mesophilic temperatures.
Leaching in Metallurgy and Metal Recovery
Jul 10, 2017 · 1) Vat Leaching: Also known as “agitated tank” leaching, the lixiviant comes into contact with the metal material in large vats or tanks, which can be stirred, enhancing the reaction kinetics. The metal containing solid, such as concentrate, ore, residue, or slag, often undergoes size reduction via crushing and grinding prior to leaching.
