Mineral processing equipment generally includes ball mill, magnetic separator, flotation machine, dryer, rotary kiln, classifier and other equipment, excluding mill.
　　In recent years, with the sustained and rapid growth of the national economy, the contradiction of resource shortage is becoming more and more serious. How to effectively use the refractory and low-grade ores in metal mines has been concerned by all aspects.
　　The general directions are as follows:
　　A. research and Analysis on the development trend and strategy of the development and utilization of metal mineral resources, comprehensive review or special summary of new technologies and equipment for efficient development and utilization of mineral resources;
　　B. metal mining enterprises effectively develop refractory, low-grade and extremely lean ores, effectively utilize tailings and industrial wastes, promote experience, practice, effect and planning of high-efficiency beneficiation and metallurgy technology and equipment, especially improve independent innovation ability, and pay attention to experimental research and application results of forward-looking technology development;
　　C metal mine difficult to beneficiate and fine-grained ore resources in the increase of common technology and support technology and other aspects of experimental research and application results. Including limonite, siderite, Specularite, fine-grained hematite and oolitic hematite, copper oxide, Complex Polymetallic mixed ore, refractory gold ore and other new technologies, new processes, new equipment, new agents and other prospective technology development, independent innovation results;
　　D metal mine low-grade iron ore, gold ore, non-ferrous metal ore and other resources efficient, energy-saving, emission reduction and other reasonable utilization of mineral processing and processing technology and equipment of combined research and application. It includes low-grade iron ore pretreatment technology (such as multiple dry magnetic separator preconcentration, high intensity magnetic separation, wet low intensity magnetic separation before grinding, etc.) and magnetic gravity separation technology, low-grade primary copper sulfide, secondary copper sulfide and copper oxide ore bioleaching technology, low-grade oxidized gold ore heap leaching, leaching AIDS, etc; 　　E. achievements of new technology and equipment for the utilization of resources such as extremely lean ore, off surface ore and off boundary ore in metal mines;
　　F. achievements of experimental research and application of technologies and equipment for efficient beneficiation, processing and recycling and combined treatment of beneficiation and metallurgy of by-products of associated ores and associated ores in metal mines;
　　G experimental research and application results of technologies and equipment for effective recovery and emission reduction of secondary resources (mining dump, beneficiation tailings, steel slag, metallurgical mud, blast furnace gas mud, sulfuric acid slag, cyanidation tailings, chromium slag, copper slag, nickel slag, etc.); H high efficiency mineral processing new equipment and wear-resistant materials of experimental research and application results.
