重介质选煤具有分选精度高，分选密度调节范围宽，可高效分选难选煤和极难选煤及适应能力强等特点，其分选精度大大高于其它选煤工艺（对中等可选性以上煤种，分选的数量效率比跳汰分选工艺高5％～10％），经济效益十分显著。近年来不仅大型设备可靠性和自动化水平有着较大幅度的提高，新研制成功的各类重介质选煤工艺与设备等先进的成果简化原较为复杂的重介质选煤工艺，进一步为重介质选煤工艺的普及创造条件。更有高磁场磁选机和耐磨泵等设备及材料的出现为降低介耗和提高辅助设备寿命前进一大步。
Heavy medium coal preparation has the characteristics of high separation accuracy, wide range of sorting density, efficient separation of refractory coal, extremely difficult coal preparation and strong adaptability, and the separation accuracy is much higher than that of other coal preparation processes More than the optional coal, the number of sorting efficiency than jig sorting technology by 5% to 10%), the economic efficiency is very significant. In recent years, not only the reliability and automation of large-scale equipment have greatly improved, the successful development of various types of heavy medium coal preparation process and equipment and other advanced results simplify the more complex heavy medium coal preparation process, and further for the heavy media The popularity of coal technology to create conditions. More high-field magnetic separator and wear-resistant pumps and other equipment and materials appear to reduce consumption and improve the life of auxiliary equipment a big step forward.
