Mechanical agitated flotation machine uses impeller and stator system as mechanical stirring to realize inflation and stirring, it is a widely used tungsten scheelite flotation equipment. http://news.chinatungsten.com/en/tungsten-information/95986-ti-12277
Flotation machine is a mini workshop for tungsten scheelite flotation, it is the basic flotation equipment, processes include adding material, stirring, heating, shaving foam, separating mineral vein are completed in this machine. So flotation machine is important in producing process of tungsten scheelite. http://news.chinatungsten.com/en/tungsten-information/95985-ti-12276
Tungsten scheelite flotation equipment usually includes mechanical agitated flotation machine and jet flotation machine. In recent years, with the continuous progress of the process, a new type of flotation equipment also added to the flotation equipment team, it is the flotation column. http://news.chinatungsten.com/en/tungsten-information/95984-ti-12275
Spiral chute beneficiation utilizes the water current flow from slope into chute, under vertical movement to separate ore and grit. It utilizes different proportion and density to separate mine and gangue mineral. In recent years, it has gradually taken place of tabling beneficiation. http://news.chinatungsten.com/en/tungsten-information/95983-ti-12274
Tungsten scheelite flotation is difficult in separation of scheelite and gangue minerals. Calcium ion affects selectivity of collector. To improve selectivity, pH value regulator shall be added to create better flotation environment for scheelite flotation. http://news.chinatungsten.com/en/tungsten-information/95933-ti-12268
Melting point of tungsten is 3410℃, boiling point is 5900℃, it evaporates slowly under high temperature, has low thermal expansion coefficient, high hardness, high density, good electric emission property. Tungsten is regarded as teeth of industry, it has wide application in industrial field, such as mine, metallurgy, machining, construction, transportation, electricity, chemistry, light industry, textile, military, aviation, technology. http://news.chinatungsten.com/en/tungsten-information/94908-ti-12211
Tungsten metallurgy products mainly include ammonium paratungstate, tungsten trioxide, blue tungsten oxide, violet tungsten oxide, tungsten powder, ammonium metatungstate, tungsten carbide powder. Ammonium paratungstate is the main intermediate product and the raw material in tungsten metallurgy products. http://news.chinatungsten.com/en/tungsten-information/94907-ti-12210
At present, China has tungsten reserve of 55% which ranks the first in the world, among which tungsten scheelite accounts for two thirds of the total reserve. However, tungsten scheelite has less quantity in rich ore and has low grade. If explored by exist process, there will be very little economic efficiency. Tungsten concentrate has small reserve, rich ore is easy to prospect and filtrate. As a result, tungsten concentrate exploration takes up 90% of the total amount. http://news.chinatungsten.com/en/tungsten-information/94906-ti-12209
Tungsten is a kind of wide distributed rare metal and accounts for 0.001% in the earth crust. World tungsten mine resources mainly locate in Alps-Himalayas and circum-pacific geological belt. China is between these two geological belt and has the world largest tungsten reserve.
Impact crusher is mine crush equipment with high efficiency, can be used in tungsten ore beneficiation.
