IMA sensors collect real-time geo-metallurgical and ore grade data during production from drill cores, drill cuttings and ore on conveyor belt or loader bucket before the material enters the processing mill, concentrator or waste rock area.
Blasthole and R/C drill chip sampling and analysis
IMA Blasthole Sampler-Analyzer, called PDSA, collects samples and dense drill cuttings data from production and R/C holes. This dense and accurate real-time data can be used to make accurate 3D mine maps of the blast benches. The PDSA is a fully automatic sampling and analysis robot that can be integrated on any manufacture’s drill rig. It requires no operators and it enables in autonomous drilling by removing sampling personnel from the blast benches. The PDSA provides Analyze While Drilling (AWD) and Measure While Drilling (MWD) data to provide accurate elemental analysis and rock/ore hardness (i.e drill / blast / crush / grind ability) information combined with ore and wasterock location coordinates.
Ore Analysis on Conveyor
IMA on-line Fast Conveyor Analyzer (FCA) used in sensing coarse primary crushed and/or fine crushed ore before it enters the grinding mills and concentrator. The role of the FCA is to fast track the ore grade and type for optimum processing by delivering immediate feedback of ore grade to loaders at the muck pile. The information is also fed forward for process optimization few hours before the ore enters mills and concentrator. Loading wrong ore type or waste rock is thus avoided, and ore blending is optimized, and different minerals can be treated with optimum and sustainable way. This reduces waste rock dilution and increases mill through put and metal recovery in the concentrator. Further ore losses can be reduced by more accurate reactive loading. All this improves mine economy and reduces mining costs.
Bulk Ore Sorting System
IMA Bulk Ore Sorting System (BOSS) technology is the most economic option for in pre-concentration for your mine. IMA BOSS typically sorts ore and waste rock and/or different grades ore by analyzing the mill feed on primary crushed ore conveyor in short time batches. No ore screening or other pretreatment is required. To proceed with the BOSS concept a simple application study is performed with your samples at IMA BOSS Laboratory. This lab study is then followed by a short pilot test in the mine with FCA unit mounted over on the mine’s existing ore conveyor. This combination of IMA BOSS lab and field studies combined with economic benefit calculation shows in a few months bulk ore sorting potential and proposed sorting arrangement for your mine.
