Mineral Field Testing

component testing

TESTING OF DEPOSITS OF MINERAL RESOURCES the process of studying the qualitative and quantitative composition and properties that make up a deposit of natural formations. The results serve as the basis for isolating and outlining industrially valuable accumulations, natural and technological types and varieties of minerals, calculating their reserves, conducting exploration and operational work, choosing a method for processing mineral raw materials, determining losses and dilution, taking measures for the best use of mineral resources and combating environmental pollution, solving a number of other tasks (see. Contouring of mineral deposits).

The process of field testing is divided into three stages: sampling, their processing and analysis (testing). Sampling is performed in outcrops, various mine workings and boreholes, both in natural occurrences and from broken or stored masses. Three groups of methods for sampling in mining are distinguished: point, linear and volumetric. The first includes ore, when the sample is represented by separate samples, the point – portions are beaten on a certain network from the walls of the mine workings, handful – portions are beaten on a grid from the surface of the beaten ore or rock in bulk, trolley, car, etc. Representatives of the second group are furrowed and hole ways. The furrow method is the most common in the practice of exploration – consists in breaking or sawing furrows of various sections and lengths depending on the power of the body of minerals and the nature of the distribution of its constituent components. The blasthole method consists in collecting material obtained by drilling holes for driving mines or specifically specified for testing. The third group includes zadirkovy and gross methods.
