Abstract

The article describes a possible improvement in mining works through application of bulk mining and total mined material pre-concentration by means of radiometric separation and small-batch sorting methods. The positive results of a wide application of one of radiometric separation methods – luminescent separation at OAO «ALROSA» operation, providing for complete mining of kimberlite, are shown. Arguments are presented in favor of achieving similar results in application of the X-ray spectral analysis method for polymetallic, chrome and gold ores through lump separation and small-batch sorting of total mined material, crushed to –50+0 mm size. Automated production lines, mounted in sea containers as modules, are designed for treatment of large quantities of mined bulk material. The modular design permits to decrease the cost of lump separators and small-batch sorting installations that are factory-assembled, and, thus, permanent structures are not required for pre-concentration stage. Broken stone production at pre-concentration stage makes it possible for mining-and-processing facilities to produce marketable product prior to construction of concentrating plant and tailings disposal system. The described technologies are proven, and may be applied for iron, manganese, chrome, copper and copper-nickel, fluorspar-feldspar, diamond and gold ores.
