Abstract

Russian needs in fluor spar are satisfied only by 57%, at the expense of self source of raw materials. At the expense of import, these needs are satisfied by 43%. Mongolian and Russian joint enterprise “Mongolrostsvetmet” is a large importer of fluorite concentrate in Russia. For the purpose of expansion of raw material base of “Bor Undur” ore-dressing and processing plant, the specialists from Scientific and Production Association "RIVS" developed the flotation concentration technology for high-carbonate Urgen deposit ore. These ores are complex, with low carbonate module (its value on blocks is 1–4). The ore has the following content of main components: 41.3% of fluorite; 40.5% of quartz; 10.5% of calcite. Nowadays, the concentration plant of “Bor Undur” ore-dressing and processing plant, processes the high-carbonate Urgen deposit ore only in the mixture (to 16%) by the current extraction ores. As a result of pre-laboratory researches, there was obtained the fluorite concentrate, which contains 97.5% of fluorite, 0.94% of quartz, 0.01% of sulphur and 0.059% of phosphorous, with extraction of 80.2% of fluorite. During the laboratory testings, there was shown the processing availability of high-carbonate fluorite Urgen deposit ore on the concentration plant of “Bor Undur” ore-dressing and processing plant, without the additional charging to the current extraction ores.
