Improving the process performance of gold cyanide leaching
Cyanide leaching of gold is carried out in very large mechanically stirred tank reactors The reactor size can be up to 5000 m3 A typical agitator configuration is two downward pumping hydrofoil impellers, which requires a low mixing power input and results in low shear rates inside the reactorDescription With over 50 years of experience, Hayward Gordon are considered experts in their field and with installations around the world and across most mineral extraction processes Hayward Gordon have established a reputation for providing quality agitators / mixers you can depend onMixers Agitators WPE Process EquipmentCyanide solution is added to the leach feed (thickener underflow) hopper, distribution box and also to the first three CIL tanks of each train (tanks 2, 3, 4, 102, 103 104) The tanks are agitated by twin impellers, with oxygen injected through lances down the hollow agitator shaftsLeaching Adsorption Resource Book
Oxygen Sparging Improves Gold Leaching
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 cause an erratic slurry flow and inefficient mixing In an effort to improve mixing the air flow is typically increased In Leach Tank Agitator Shaft with Blades Used Agitators Gearboxes for Sale Agitator shaft to suit Lightnin’ 780Q drive fitted with two sets of three agitator blades Stock code: AGISHAF001 MACA Interquip is a leading provider of new and reconditioned mining equipment If you’re interested in enquiring about one of our current products available online, or if you need assistance with Leach Tank Agitator Shaft with Blades MACA LIMITEDReduce material' settling in gold leach tanks Hydrometallurgy Apr 4, 2017 Hydrometallurgy: Leaching in Heap, Vat, CIL, CIP, MerrillCrowe, SX on how to reduce settling of materials in leaching tanks in Gold production Do you have the correct agitator(s) installed in your leach tanks?

For example, conicalbottomed Pachuca tanks with single sparging points (common South African practice prior to about 1980) and flatbottomed leach tanks with multiple sparging points, or simple downtheagitatorshaft addition, have all been used In a few cases, particularly when treating ores that contain oxygenconsuming minerals, pure oxygen [5] or hydrogen peroxide [4] have been added to Gold Leaching( carbon in leach) process is widely used in the newly built gold leaching plants in recent years, and a lot of plants are changing into CIL as well Gold Leaching CIL process is suitable for the treatment of oxidized gold ore with low sulfur content Gold Leaching Carbon in Leach JXSC MachineThe CIL process The carboninleach (CIL) process, illustrated in Figure 3 is a variation of the CIP process In this process carbon is added directly to the leach circuit so that the leaching and adsorption processes proceed simultaneously Capital cost is reduced, as only one set of agitators The process design of gold leaching and carboninpulp

Autoclaves and agitator systems for hydrometallurgy
Large Tanks and Leach Tank Agitators Since the quality of ore bodies often decreases as rich resources get depleted, one trend is to process more slurry volume in one plant or module which leads to further increased vessel sizes for current and future projectsThe slurry is conveyed to a series of leach tanks The slurry is agitated in the leach tanks, either mechanically or by means of air injection, to increase the contact of cyanide and oxygen with the gold and enhance the efficiency of the leach process The cyanide then dissolves gold from the ore and forms a stable goldcyanide complexAgitation Leaching Theory And Practice Biology EssayAgitators are used in various mixing, solids suspension and gas dispersion duties and are used in both in atmospheric reactors and autoclaves References range from Conditioners and filter feed tanks to CIL, CIP, BIOX, strong acid leach and precipitation reactorsOKTOP® Agitators Outotec
