In recent years, the contradiction between the shortage of international resources has intensified.
How to make effective use of refractory ore and low-grade ores in metal mines has received attention from various parties.

There are ball mill, magnetic separator, flotation machine, dryer, rotary kiln, classifier and so on.

The direction of mineral processing industry is:

A. The development trend and strategic research analysis of the development and utilization of metal mineral resources, the comprehensive review or special review of new technologies and new equipment for efficient development and effective use of mineral resources;

B. Metal mine enterprises effectively develop difficult ore dressing, low-grade ore, extremely poor ore, and effective use of beneficiation tailings and industrial waste, and promote the experience, practice, effectiveness, and planning of high-efficiency metallurgical technology and equipment, and in particular, improve independent innovation capabilities. , Pay attention to the experimental research and application results of forward-looking technology development;

C. Achievements in the research and application of refractory metals and fine-grained ore resources in metal mines in increasing common technologies and supporting technologies. Including limonite, siderite, mirror iron ore, fine-grained hematite and hafnite hematite, copper oxide ore, complex multi-metal mixed ore, refractory metallurgical ore, new technologies, new processes, new equipment, Experimental research and forward-looking technology development of new pharmaceuticals, and the results of independent innovation;

D. Metal mines Low-grade iron ore, gold ore, non-ferrous metal ores and other resources such as high-efficiency, energy-saving, and emission reduction, and the results of experimental research and application of technologies and equipment for the rational use of beneficiation and processing.
