  • Grade Control | Bruker

    Grade control is the classification of reserves into ore, low grade, waste material or metallurgical types XRay Fluorescence (XRF) is the most accepted analytic technology for grade control in mineral production and processing Bruker’s wide range of XRF instrumentation can meet any need in production monitoring for mining in the goal of separating waste from oreYandi mine 5 km 7,480,000 S Yandi Railway Creek Yandi open pit Palaeochannel Abzalov et al, 2010: Optimisation of the grade control procedures at the Yandi ironore mine, Western Australia: geostatistical approach, Applied Earth Science Journal, v119, No3, p132 142Optimisation grade control procedures at the open pit(2010) Optimisation of the grade control procedures at the Yandi ironore mine, Western Australia: geostatistical approach Applied Earth Science: Vol 119, Grade Control and Geostatistics of Iron Ore Deposits Part 2, pp 132142Optimisation of the grade control procedures at the Yandi

    Abstract In some mining operations, one of the most important roles played by the geologist is the supervision of grade control In an openpit operation, this involves the sampling of blasthole cuttings produced by downthehole hammer drills and the classification of bench reserves into ore, low grade or waste material, or into various metallurgical typesGrade control is a process of maximising value and reducing risk It requires the delivery of tonnes at an optimum grade to the mill, via the accurate definition of ore and waste It(PDF) Grade control geological mapping in undergroundBy Christian H Calderon Arteaga, Senior Technical Support Specialist Ore control technology from Hexagon has helped Goldcorp’s Peñasquito mine in Mexico to meet the challenges of a declining metal production profile Processing time for ore control has seen an average reduction of 75 percent while monthly reconciliation processing time has beenParing the processes: Faster ore control Hexagon Mining

  • Ore Grade Reconciliation Techniques – A Review

    The essence of ore grade reconciliation is to identify, analyse and manage variance between planned and actual results in a way that highlights opportunities A consistent record of poor reconciliation is an indication that this variance has not been adequately managed This would inevitably result in significant economic impact on mining companiesquantities of highgrade mineral ore deposits 112 Development If the mineral ore exploration phase proves that there is a large enough mineral ore deposit, of sufficient grade, then the project proponent may begin to plan for the development of the mine This phase of the mining project has several distinct components11 PHASES OF A MINING PROJECT ELAWOre grade reduce due to mixture of waste ore and loss of rich ore powder during the mining process is called dilution Dilution rate is generally adopted to represent the variation degree of ores from quality during the mining process It is the reduced percentage of ore grade during the mining processCalculation and Management for Mining Loss and
