InLine Leach Reactor Gekko
Gekko’s easy-to-use InLine Leach Reactor (ILR) offers superior gold recoveries in a high efficiency, low cost system. The innovative ‘rolling barrel’ design of the ILR agitates and leaches coarse gold concentrates under intensive cyanide and oxygen conditions.
MODELING OF GOLD CYANIDATION
received attention and new rate equations expressing the gold leaching are still developed. The effect of leaching parameters on gold cyanidation is studied in this work in order to optimize the leaching process. A gold leaching model, based on the well-known shrinking-core model, is presented in this work. It is proposed that
The process design of gold leaching and carbon-in-pulp
The process design of gold leaching and carbon-in-pulp circuits pulp in an environment appropriate for leaching in the CIP reactors. This additional leaching provides additional economic benefit. The CIL process The carbon-in-leach (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
Hydrometallurgy: Leaching in Heap, Vat, CIL, CIP, Merrill
While intensive leaching has its advantages, for example the gold enters the same soluble gold recovery stream as the CIL/CIP gold and more consistent 'quality' Dore is produced, smelting is a reasonable route however does typically require a larger furnace, more fluxes and if sulphides are present, a more elaborate fume capture and scrubbing

Increase Your Gold Recovery With A Sepro Leach Reactor
Cyanidation is the most common method of leaching gold from ore, but not all leach reactors are made equal. On large scale gold recovery operations, even the smallest of changes can have a major impact on overall performance. While a difference of 98 to 99% target mineral recovery may not seem substantial, it could mean the difference of millions of dollars in revenue, potentially creating a
Gold Leach arc-conseils.fr
Gold CIL & CIP Gold Leaching Process Explained CCD. The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. CIL stands for carbon-in-leach. This is a gold extraction process called cyanidation where carbon is added to the leach tanks (or reaction vessel) so that leaching
IN MINING & MINERAL PROCESSING
Adsorption is most commonly recognised as Carbon in Leach (CIL) or Carbon in Pulp (CIP), where the processes use activated carbon for the gold to leach onto. CIL is a process of cyanidation as the carbon is added into the leach or reactor tanks. Leaching, as well as adsorption, will take place in the same leach
Gravity Leaching With the ConSep ACACIA Reactor — Results
Gravity Leaching With the ConSep ACACIA Reactor — Results From AngloGold Union Reefs J Campbell1 and B Watson2 ABSTRACT The ConSep ACACIA Reactor is a device, which utilises a high intensity cyanidation process to achieve very high, usually near total, recovery of gold from gravity concentrates. The process utilises a fluidised bed and a
THIOSULPHATE LEACHING AN ALTERNATIVE TO CYANIDATION
alternative to cyanidation for some gold bearing ore bodies. Whether the leaching is performed in stirred tank reactors or heaps, the size and type of equipment needed for a thiosulphate leaching flowsheet is very similar to a conventional cyanide leach. SGS is a global technical leader in the field of thiosulphate leaching, and our
