IPJ - Automation Automatic start and stop sequence operation Provides monitoring of streams and reaction to process problems Enables automatic mass balancing
ALTA10 IPJ – Integration into circuits Through bed jigging Ceramet ragging SG 2 to 5.0 Gravity feed or pump feed Direct coupled pumps Pressure monitoring and dump valves Polyurethane piping spools
ALTA10 ILR - Technology Slow rolling drum 1-2 rpm Standard reagents only High dO levels Up to 10 ppm using H 2 O 2 as the oxidant and up to 25ppm when using O 2 Batch Leach reactors. Models to treat batches of 900 - 24,000 kg Continuous leach reactors. Models up to 2.1 t/hr installed and Super ILR available up to 9 t/hr
ALTA10 Batch ILR – Improvements Single solution cone, single pump Automation provides largely hands free operation PLC program optimisation ILR rolling drum technology – The most efficient chemistry!
Batch ILR – Sizing Tool GRG Testwork and/or Plant Survey Data AMIRA P420 Gravity Model – Estimates the size of a gravity circuit required The model provides a clear picture of the recovery gain by increased % of product feed. In a typical grinding circuit application the tool will direct you as to which is the more appropriate stream to feed the BCC. ILR can then be selected to match the BCC yield ALTA10
Fully engineered package of screen, concentrator, ILR, frames, piping, electrical, automation, installation and commissioning. Pre-assembled during fabrication to ensure rapid installation. Suitable for new plant or existing upgrade. Standard designs at various tonnages completed and repeatable (drawing packages and or complete assembly options available) Specifically designed to assist engineers and operators in meeting tight deadlines in a climate that is seeing more gold projects fast tracked, juniors starting operations on strict capex budgets and engineers pushed on lead times.
Batch ILR Case Study – St Ives ALTA10 ILR3000BA in operation since 2003 >98% ILR Leach recovery Overall gravity recovery 20- 30% ILR produces >100k oz’s per annum ILR Impacts overall recovery by approximately 2.5% High Availability – running daily since 2003 High Recovery (Increased gravity recovery by 8%) Integral part of the overall plant ILR3000BA replaced shaking table
Batch ILR Case Study – Target ALTA10 ILR100BA in operation since 2002 >98% ILR Leach recovery Overall gravity recovery ~50% ILR Impacts overall recovery positively High Availability High Recovery Integral part of the overall plant Has eliminated historical security concerns St Ives, Agnew, Kelian & Target ILR Batch units formed the foundation of batch IC technology to grow to more than 150 installations of the unit process globally in <10 years!
