Major geological faulting and associated jointing was intruded by a multi-phased quartz-monzonite porphyry about 9.8Ma, resulting in a large area of intrusives being in contact with the older Jumasha limestone Formation. The calcic skarn thus produced was mineralised by extensive hydrothermal solutions, forming at least siSee more on mining-technology

  • Grade Control Bruker

    Grade control is the classification of reserves into ore, low grade, waste material or metallurgical types. X-Ray 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 ore.

  • What is grade control and how can it save you time?

    Aug 14, 2015  At one point in an operation, mining becomes unprofitable because the grade of the metal is too low – the value of the metal in the ore is less than what it costs to mine it. Grade control stops businesses from running at a loss. Milling. The milling process is designed to be as efficient as possible by being performed at a specific grade.

  • 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 companies.

  • Reduce ore dilution and loss in open pit mines BMT

    Ore loss occurs when material containing grade (ore) is incorrectly sent to a waste dump. When a cost is given for Ore Loss, it is the sale value of the metal (gold, copper) recovered from this ore (i.e. ore tonnes x grade x recovery rate x metal price). Dilution occurs when waste is unintentionally with material containing ore and sent to the ...
