Tungsten concentrate is fragile mineral, it can easily form into slime during beneficiation process. So there is useful tungsten element in tungsten tailings.

Tungsten concentrate coarse separation is gathering tungsten ore from mine, then enters the first premium grade separation process before gravity separation. Due to uneven distribution of tungsten concentrate in quartz vein mines, tailings mixed in the gathering process is huge. Separate tungsten concentrate and tailings at primary stage can promote efficiency of subsequent processes, save cost, time and lower wastage.
Flotation column is a new type of tungsten scheelite flotation equipment, it has a simple structure, small footprint, low cost, high degree of automation, low infrastructure investment, good flotation index and many other advantages, and gradually become mainstream in tungsten ore flotation. http://news.chinatungsten.com/en/tungsten-information/95988-ti-12279

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
