  • How Bulk Ore Sorting Can Reduce Water and Energy

    Bulk ore sorting has the potential to either delay or eliminate this capital spend, while delivering higher grade material to the mill. The increased recovery and profitability results in an extension of the mine life, increases the return on investment in the mine and delays costly site rehabilitation. So the potential benefits are far greater than the reduction in energy and water

  • Bulk ore sorting improves profitability and sustainability

    Bulk ore sorting could also be used to separate ore types to treat via different process routes, or to reduce dilution and ore loss in mining operations by improving grade control. It is an efficient way to deal with uncertainties of grade, particularly where the complexity of mine geology makes the estimation of grade difficult. This helps the mining operation to achieve the planned cut-off

  • Bulk mining Article about bulk mining by The Free

    The Ardea concept to incorporate lower-grade, disseminated mineralisation into a potential bulk mining operation with DMS upgrade of feed grades, is consistent with major operations in the central Lachlan Fold Belt, which are all low grade, bulk excavation-based mines.

  • Bulk Ore Sorting in Base and Precious Metals

    Ore sorting is a very broad concept that includes sorting by grade, particle size, and mineralogy across many different mineral processes. Continuous analysis of ore in base and precious metal applications is best accomplished using rapid online elemental analysis, with either PGNAA (Prompt Gamma Neutron Activation Analysis) or PFTNA (Pulsed Fast Thermal Neutron Activation).

  • Underground mining (hard rock) Wikipedia

    Production mining is further broken down into two methods, long hole and short hole. Short hole mining is similar to development mining, except that it occurs in ore. There are several different methods of long hole mining. Typically, long hole mining requires two excavations within the ore at different elevations below surface, (15 m 30 m apart). Holes are drilled between the two

  • The Broken Hammer Mine David K. Joyce

    Broken Hammer Mine. By David K. Joyce. Introduction. The Broken Hammer PGE-copper deposit was originally discovered by Wallbridge Mining Company Ltd geologists in the fall of 2003, using grass-roots exploration techniques. The original discovery was made by surface mapping and prospecting while geologists were following up on an IP anomaly. Peeling back moss the geologists came across

  • Recovery of Broken Ore Stocks Left on the Mine Floor and

    Use of conventional LHD units and scrapers on an uneven floor underground leaves behind a significant portion of metal (or precious stones) contained in the already broken ore stocks. Depending on the mining method, this material is often never recovered (ie it is wasted) when utilising conventional mining methods and equipment. The portion of metal...

  • Bulking/Swell of Excavated or Mined Materials

    Bulking/Swell Factors for Various Excavated/Mined Materials. The swell factor expressed in percentage is the amount of volume increase from bank volume (undisturbed, in place state) to loose volume (disturbed, excavated state) of the material due to voids (air pockets) added to the material after excavation. Example using metres: The excavated area is 200 metres long 20 metres wide and 2

  • Underground Mining Methods — New Pacific Metals

    This bulk underground mining method involves mining large amounts of material from a single stope similar to cut and fill, this method starts at the bottom of a level and moves upward. Ore is removed from the bottom, and then more ore is blasted from a higher level that falls to the same level to be removed, with the process repeating up the orebody.

  • Ore Wikipedia

    Ore is natural rock or sediment that contains one or more valuable minerals, typically metals, that can be mined, treated and sold at a profit.Ore is extracted from the earth through mining and treated or refined, often via smelting, to extract the valuable metals or minerals.. The grade of ore refers to the concentration of the desired material it contains.
