Tank Leaching Stirred

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. In the case of sulfide leaching as in bioleaching operations aeration is needed and is accomplished by blowing air under the stirrer.

Hydrometallurgy - Wikipedia

Tank leaching 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.

Tank leaching - Wikipedia

Leaching reagents are added to the tanks to achieve the leaching reaction. In a continuous system the slurry will then either overflow from one tank to the next, or be pumped to the next tank. Ultimately the “pregnant” solution is separated from the slurry using some form of liquid/solid separation process, and the solution passes on to the next phase of recovery. In vat leaching the solids are loaded into the …

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.
