Development of mineral processing equipment

Mineral processing equipment has ball mill, magnetic separator, flotation machine, dryer, rotary kiln, classifier and other equipment, excluding the mill. In recent years, with the sustained and rapid growth of the national economy, the contradiction of resource shortage is becoming increasingly serious. How to effectively utilize the refractory and low-grade ore in metal mines has been concerned by all aspects.

In recent years, with the sustained and rapid growth of the national economy, the contradiction of resource shortage is becoming increasingly serious. How to effectively utilize the refractory and low-grade ore in metal mines has been concerned by all aspects.

The general directions are as follows:

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

B metal mining enterprises should efficiently develop refractory, low-grade and extremely lean ores, and effectively utilize beneficiation tailings and industrial wastes, etc., and promote the experience, practice, effectiveness and planning of high-efficiency beneficiation and metallurgy technology and equipment, especially improve the ability of independent innovation and attach importance to the experimental research and application results of forward-looking technology development;

C metal mine difficult to mineral processing and fine-grained mineral resources in increasing the common technology and support technology and other aspects of experimental research and application results. It includes the experimental research and forward-looking technology development and independent innovation achievements of 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 and new agents;

D metal mine low-grade iron ore, gold ore, non-ferrous metal ore and other resources efficient, energy-saving, emission reduction and other mineral processing and processing technology and equipment experimental research and application. It includes low-grade iron ore pretreatment technology (such as multiple dry magnetic separator pre separation, high-intensity magnetic separation, wet low-intensity magnetic separation before grinding, etc.) and magnetic gravity separation technology, microbial leaching technology of low-grade primary copper sulfide, secondary copper sulfide and copper oxide ore, heap leaching of low-grade oxidized gold ore and Leaching Aids The achievements of new technology and equipment in utilization of extremely poor ore, surface ore and boundary ore in metal mine;



F. experimental research and application results of high-efficiency mineral processing, processing and recycling of by-products of associated ore and associated ore in metal mine and combined processing technology and equipment of dressing and metallurgy;

G achievements of experimental research and application of technologies and equipment for effective recovery and emission reduction of secondary resources (mining dump, ore dressing tailings, steel slag, metallurgical mud, blast furnace gas mud, sulfuric acid slag, cyanide tailings, chromium slag, copper slag, nickel slag, etc.); h. experimental research and application results of new high-efficiency mineral processing equipment and wear-resistant materials.
