First, the type of technology Non-metallic mineral mining and efficient technology. Second, the scope of application Various types of sillimanite resources. Third, technical content (1) Basic principles Sillimanite ore divided into two basic types, one biotite sillimanite schist, it is easy to mineral stone, two pomegranate sillimanite schist and garnet biotite sillimanite schist, containing a large number of iron-containing minerals, mineral refractory metal, the original It is difficult to select qualified products in the floating-magnetic process. By strengthening the pre-magnetic separation, a large number of "floating-like" iron-containing minerals are removed to increase the floatability of the silicon ore minerals. (2) Key technologies Adopt high-efficiency and energy-saving wet magnetic permanent magnet magnetic separator to pre-magnetically select the minerals before flotation, and discard about 30% of iron-containing minerals, thereby reducing the content of iron-containing mineral impurities in refractory minerals affecting flotation operation. The floatability of the sillimanite mineral is improved, and the product quality pass rate is increased from about 40% to over 95%, so that the original unusable ore is changed to an available ore. (three) process Sillimanite ore---crushing---grinding---de-mud---wet strong magnetic permanent magnet magnetic separation---flotation---dehydration---drying---dry type magnetic permanent Magnetic magnetic separation - sillimanite concentrate. Fourth, the main technical indicators The “three rate†indicators of Tiansheng Company’s original (state-owned enterprises) were: mining recovery rate of 80%, ore recovery rate of 56%, and depletion rate of 7.5%. After the private use of technology, the “magnetic magnetic magnetic†technology was adopted. The “three rate†indicator is: mining recovery rate of 95%, ore recovery rate of 80%, and depletion rate of 4.8% or less. V. Typical examples and results Since the adoption of this technology in 2006, Jixi Tiansheng Non-Metal Mining Co., Ltd. has broken the original “floating magnetic†process, which has made a major breakthrough in mineral processing technology, and solved major problems such as low qualified rate of concentrate and low recovery rate. This process is suitable for all types of sillimanite mines and is the first in China. Since its transformation in 2006, Tiansheng has been selected into more than 250,000 tons of various grades of sillimanite ore and produced more than 15,000 tons of sillimanite concentrate. Six, promotion prospects The technology adopts the magnetic-floating-magnetic beneficiation process for the characteristics of sillimanite in Jixi area of ​​Heilongjiang Province, which improves the grade and recovery rate of concentrate. It has the promotion value in the mining and beneficiation of the same type of sillimanite deposit in China, and the sillimanite mineral Resource conservation and comprehensive utilization are of great significance.
