World demand for metals is growing, making the low-grade ore in the study of metal extraction even more urgent, due to continuous development and depletion of mineral resources of zinc sulfide, how to develop and make good use of zinc oxide ore resources appear to be increasingly important. Zinc o

The main factors affecting the jaw crusher work are the angle of the corner and the number of revolutions. The angle of the jaw crusher is the angle between the momentum and the quota. According to the calculation, the maximum angle of engagement can reach 32, but in actual use, it is less than 25

The bit is directly broken part of the rock, its shape, structure, material, processing technology, etc. directly affect the crushing effect and the life of the bit. The drilling requirements for the drill bit are: Shape reasonable structure, high drilling speed, long life, wear resistance, suffic

In non-metallic mineral processing plants, by a number of machines and equipment is generally assembled and completed connection lines, and the installation and maintenance of machinery and equipment in the plant is an important part of the mechanical work. The quality of installation and maintena

Semi-industrial experimental study on flotation separation of mercury bismuth symbiotic sulfide ore Link of Liu Yunjie Chen Chang Arts World Bank Shaanxi Institute of Geology and Mineral Resources Abstract treated in day 25 tons of mine ore processing plant, a small experimental research as th

Zirconium and hafnium have opposite nuclear properties, but their chemical properties are very similar. The content of antimony in natural zirconium is generally 2% to 3%. For atomic energy grade sponge zirconium in nuclear power, the zirconium content in zirconium is less than 0.01%, so zirconium

The process of transporting the collapsing ore from the working surface to the transportation level is called ore transportation. Its labor and materials costs account for 30% to 50% of the total recovery cost. The productivity of ore transportation determines the intensity of the mining and the co
