InLine Leach Reactor
Maximise recoveries from gravity gold concentrates
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.
The ILR is available as a completely automated batch model for processing small volume gravity gold concentrates from batch separators; and, as a continuous model for treating high-throughput gold and complex sulphide concentrates from an InLine Pressure Jig and flotation circuits.
More than 150 installations globally
How the ILR Works
The automated Batch ILR treats up to 24 tpd of feed containing accumulated gravity or flotation concentrates of fine and coarse gold. Whereas, the Continuous ILR treats continuous feeds of high tonnage and/or low grade concentrates from gold and complex sulphide ores.
Both the Batch and the Continuous ILRs work to chemically leach metal from ore concentrates using the same separation principle. The ILR’s horizontal rolling bottle design keeps particulate matter in suspension and continuously mixes to accelerate a chemical reaction within the solution.
The ILR receives gravity concentrates or flotation concentrates into its enclosed rolling drum. Inside the drum, the ore concentrates mix with a typically strong 1-2% cyanide solution and pure oxygen (in the case of gold extraction), known as intensive leaching. Specialised baffles inside the drum keep solids in constant contact with the chemical solution. The correct combination of chemicals and ore, plus the slow rolling action of the drum, creates a highly efficient leaching reaction.
When leaching is complete, the pregnant metal rich solution is clarified and transferred to a metal extraction circuit. The leftover cyanide solution is recycled and remaining solids are discarded.
Optimise Your Ore
The flexible ILR is designed to deliver the fastest leach reaction kinetics for many ore types. The ILR accommodates different leach chemistries and reagent regimens.
Because every ore and every plant is different, the best mineral recoveries are obtained when the ILR’s leaching parameters are optimised to the specific mining operation.
Gekko offer in-house laboratory pre-testing for the ILR and recommend laboratory optimisation for every new ILR installation. The laboratory results are directly scalable to the full-size ILR. Gekko guarantee ILR recoveries when Gekko laboratory services conduct the leach testing and optimisation.
