nomennclature of leaching agitation tank

A new look at Agitated Tank Copper Leaching Agitated Leaching The agitated leaching method is limited to those ores or to that portion of those ores that because of particle size do not permit free passage of leach solution through the interstices between the ore particles and thus cannot be effectively treated by heap or vat leaching

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 Tanks are typically equipped with agitators baffles

Gold Leaching Agitation Tanks Dilution during agitation varies from 1 of solution to 1 of solids by weight to 3 of solution to 1 of solids occasionally higher probably averaging 2 to 1 Operation is continuous through a series of agitators preferably three or more to minimize any tendency for shortcircuiting

Modern Leaching Plant Design If feed is introduced at the top of the tank discharge should be through a riser from the bottom area of the tank An alternate arrangement involves using a downcomer to direct the feed to the bottom of the tank while the discharge is by overflow from the top When pulp is discharged through a riser

Pachuca tanks are hydrometallurgical reactors used for the leaching of nonferrous minerals They are cylindrical vessels that normally have a conical bottom and include a central draft tube tube and rising through it in the form of bubbles

Leaching is typically performed in steel tanks and the solids are kept in suspension by air or mechanical agitation Air agitation in carried out in conicalbottomed leach tanks Browns or Pachuca tanks was widely practiced in the early years of cyanidation but has been overtaken in recent times by more efficient mechanical agitation with reduced energy requirements and improved mixing efficiency

Ineffective Agitation – Reduction of solids in suspension Generally leach tank agitators are designed to keep the pulp in motion ie down the centre out to the wall an up the tank sides In some leach tanks air blowers introduce air flow below the agitator blades which can

Sep 27 2019 · In the gold cyaniding process leaching agitation tank is applied to leach and carbonabsorb ore pulps whose fineness is 200 meshes and whose density is less than 45 Under similar circumstance it is also applied to agitation and leaching in metallurgy chemical and light industry

Leaching reagents in the form of cyanide and an oxidant such as air or oxygen are added after thickening Leaching takes place in a series of agitated leach reactors or pachucas Before leaching the pH of the pulp is normally adjusted to a value of around 95–11 to ensure minimum loss of cyanide as hydrogen cyanide

offers 589 agitated leaching tank products About 36 of these are leaching tank 24 are other mining machines and 1 are chemical storage equipment A wide variety of agitated leaching tank options are available to you such as ac motor dc motor

Vat leaching involves contacting material which has usually undergone size reduction and classification with leach solution in large vats 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

The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon CIL stands for carboninleach This is a gold extraction process called cyanidation where carbon is added to the leach tanks or reaction vessel so that leaching and adsorption take place in the same tanks
