  • Measurement of mass flow and density in salt production

    The density of the mixture is approx 13 kgl that of pure brine approx 115 kgl l Liter In order to improve the environmental balance the limeplaster mixture may no longer be disposed of in lakes Instead the hollow spaces created during solution mining for example can be

  • Measuring and modelling of dry bulk rock density for

    Abstract Rock density information is needed for the estimation of ore tonnage and also for determining the amount of contained metal this is because mineralisation grades are usually reported as a ratio of the economically viable components metals or minerals to weight units eg gramstonne

  • Measuring the Gas Content of Coal A Review

    Coalbed gas content measurements are commonly used in mine safety as well as coalbed methane resource assessment and recovery applications The density of the drilling fluid influences the time during sample retrieval when desorption is assumed to begin Diamond 1994 Once mining is underway gas content testing can be used periodically

  • Dry Density Ore Volume tonnage Estimation amp Moisture

    Dry Density Ore Volume tonnage Estimation amp Moisture Content Measurement Hard Rock miners need to know insitu dry bulk density to accurately estimate the amount of resource in the ore body and do reserves calculations but no direct downhole measurement of dry bulk density is possible

  • Porosity and Bulk Density of Sedimentary Rocks

    densitybulk density relation was 255 percent where bulk volume was determined by the displacement of water by a previously wetted specimen but 246 percent where bulk volume was determined by mercury displacement Steinhoff and Mell 1924 using 73 cubes of porous refractory material 2 em along the edges found that the

  • Ore thickener density measurement VEGA

    Extracted minerals are fed to the thickener as a slurry via a trough The solids are settled out into the bottom of the tank in a process accelerated through the addition of flocculants Precise density measurement of the slurry underflow is necessary for effective control of the ore thickener

  • Reservoir Rock Properties of Coal Measure Strata of the

    measure rocks and their distances from mining activity In addition to the overall reservoir and strength properties the types and thicknesses of coal measure rocks at the roof of a mined coal seam cause borehole stability problems during miningWhittles et al 2007 described the application ofa computational model FLAC2D to simulate
