An APIC purpose-built and stand-alone jigging plantordered by an iron-ore producer and exporter, for its iron-ore project near Hospet, is the first jig to have been suppliedby Tenova Delkor to the iron ore sector. The jig, which wasmanufactured in India, has designed processing levels of150 t/h of (-) 8 mm (+) 3 mm float ore (naturally liberatedore) to separate it from the siliceous rock.
The 2.5 m wide jig, an APIC 17 jig, has three compartmentsand two shaft gates. Before the award of the contract forthe jig, the suitability of APIC jigging technology for thisapplication was proved in test work. This showed goodgrade and recovery, well within the expectations of the client.The percentage iron in the product varied between 64.5 %and 65.5 %, with an iron recovery of 80 % and an average

mass recovery of 72 %. In addition to this, the jig couldrecover an additional 16 % by weight as middling productat a grade of 47 %, which would be utilised by the client infuture.The test work utilised a unique technique developed in-house for predicting the process performance ofindustrial-scale jigs by mathematically modelling test resultsfrom laboratory-scale air-pulsed jigs.The technique thus permits, with far greater confidence thanwas previously possible, selection of industrial systems thatwill provide an acceptable separation of the components ofjigged material in an economically feasible residence time.The technique applies the ASTRAD (Advanced StratificationTransport Rate And Diffusion) jig process model, which,amongst other valuable features, has the ability to determineimprovements in jig yield as a function of jig size and feed

rate. It can also determine the range of yields achievableover an ore body that has a variable but known washability(density distribution), including ore blends.The APIC Jig is an efficient gravity separation process usedto clean saleable material from waste / raw material byseparating particles of different densities in a homogenousbed of granular material.
