  • Grade control geological mapping in underground gold vein

  • Mine Grade Control Reconciliation SRK Consulting

    Optimize mine planning and profitability by understanding the geological controls on orebodies An appreciation of the geological spatial controls to mineralization is fundamental to mine operation optimization, nearmine exploration, resource estimation, geotechnical engineering, and mineral processingIn underground operations, grade control may involve the mapping and sampling of stope faces, sampling of tram car loads or drawpoint muckpiles, broken rock at a recently blasted face, jackhammer cuttings or diamond drill coresGrade Control SpringerLinkIn underground operations, grade control may involve the mapping and sampling of stope faces, sampling of tram car loads or drawpoint muckpiles, broken rock at a recently blasted face, jackhammer cuttings or diamond drill coresGrade Control SpringerLinkThe process of grade control comprises dat a collection, data integration and interpre tation, local resource/reser ve estimation, input into final stope des ign, supervision of development and(PDF) Design of grade control sampling programs for   Gold mines and gold deposits are often categorized by the average proportion of gold contained in the ore at the site This is also known as the ore grade 1 What Does the Grade of a Gold Mine Refer To?

  • Grab sampling for underground gold J mine grade control

    Geologists in some underground gold mines collect grab samples from broken ore piles or trucks as a method of grade control It is often known as muck sampling Generally, the goal of grab sampling is to try and reconcile the mined grade at the ore source to the predicted grade and/or predict the mill feed gradeGrade control in the pit is based on the sampling of blast hole cuttings, the grade and metallurgical character of which are determined at the metallurgical laboratories in the mill building This information is entered into the ore grade control model, based upon which the various ore blocks are staked in Mining Milling Centerra GoldThe process of grade control broadly comprises: data collection, integration and interpretation, supervision of development and mining, local estimation and input into stope design, stockpile and mill feed management, and leading ultimately to reconciliation In many cases, grade control samplesIntegrating the Theory of Sampling into Underground Mine As a rule of thumb, open pit mining can process ore for $10 per tonne and, where the ore grade is more than double that at $20 per tonne, results would be economic Consider that 1% of a metric Making the grade: understanding exploration Depletion by Mining The availability of grade control and production data from a definable part of the orebody makes it possible to extract the ore reserve estimated for that part of an orebody from the total mineral resource estimates This subset from the total mineral resource estimates is termed Ore Reserve Depleted by Mining [ 4]Ore Grade Reconciliation Techniques – A Review
