Initially phenomena in the development of domestic and manganese ore processing equipment is what Kay march toward the four modernizations singing, the need for the introduction of foreign equipment and manganese ore beneficiation to meet our designers understand the current situation of manganese ore dressing equipment manufactured abroad. The development of mineral processing equipment directly promotes the reform of mineral processing technology. The quality of manganese ore dressing equipment will directly affect the yield and quality of the ore concentrate. At present, it has been valued and paid attention by the majority of mineral processing workers. In recent years, foreign manganese ore beneficiation equipment has made great progress in using modern science and technology to improve the original manganese ore beneficiation equipment to high efficiency and large-scale development.

Foreign studies on manganese ore dressing have been going on for many years and have accumulated a wealth of practical experience, but there are still many problems. For example, in the processing of small pieces, granules impregnated with manganese oxide ore, the concentrating plant has lower selection index, and the Mn content in manganese concentrate is not high; the further treatment of manganese ore is another major problem in the processing of manganese ore by foreign concentrators. The manganese loss in the slime is serious, which directly affects the recovery rate of manganese in the manganese concentrate. Manganese ore containing phosphorus and phosphorus there to be professional and technical issues, particularly the problem is particularly prominent for the phosphorus present in the ore material in the form of compounds in the field of foreign expertise still can not solve this problem. In this field, the chemical leaching method used in the treatment of manganese-containing gold ore in the United States has limitations. Except for the carbamic acid extraction method, the other methods are in the laboratory research stage.

China is the world's No. 1 gold ore producer and consumer, but the characteristics of “poor, fine, miscellaneous and scattered” gold resources are relatively difficult to develop. In recent years, gold ore beneficiation equipment has become the center of research and development in the world. The new technologies focused on the research of gold ore dressing equipment in China are mainly focused on: implementing the strategy of “gold extraction and silicon reduction”, which is the fine of the gangue containing gold silicate. Complex processing of gold ore, such as granular inlaid magnetic gold ore, research and application of new crushing and grinding, screening, magnetic separation and flotation equipment . Key technologies for “gold extraction and miscellaneous” include reverse flotation technology and the application of collectors in universities , the application of new magnetic separation equipment and technology, and the application of flotation columns. The gold ore processing technology for the fine-grained inlays of gold-containing silicates, such as the gold-bearing silicate, the gold ore, and the gold-gold mine, has been greatly developed in recent years. In the development and application of emerging crushing grinding, screening, magnetic separation and flotation equipment, in recent years, it has achieved “multiple crushing and less grinding” to achieve energy saving and consumption reduction of gold ore beneficiation equipment.
