Dense Media Separation – a Valuable Process for ...

The "Condor" Dense Media Separator is a dynamic cylindrical separator. In the DMS unit, the dense media is pumped from the lower end of the cylinder (medium inlet 1 and 2) as shown in . Figure 1. Utilising gravitational and centrifugal forces, a tangential or involute inlet forces the media to spiral alongside the wall, creating a vortex that transports the high pressure dense media upwards.

Barium | Minerals Education Coalition

Barium (Ba) is obtained chiefly from the mineral barite. Barium is a soft, silvery, reactive metal. Because barium is so dense it is commonly used in some alloys, for example in spark plugs and ball bearings. As of 2013, China, India and Morocco were the world's largest producers of barium. In the U.S, barite is mined primarily in Nevada and Georgia.

The SMD is a fluidized media mill which means, the stirrer speed is high enough to distribute the media throughout the slurry regardless of media density, forcing particle and media contact. The SMD power intensity is optimized to achieve efficient grinding, limit wear, and allow for heat dissipation in the case of a high energy grind.

Dec 16, 2013 · Answer Wiki. The pulp density is adjusted to a value (t/m3) that lies between the densities of your ore and the waste rock. The heavier particles will then sink in the slurry and the lighter ones will float (sink-float or dense media separation). The FeSi has to be very fine so that it does not settle easily.

Barite: The mineral Barite information and pictures

Barite is the main ore of the element barium. It is also important in the manufacture of paper and rubber. Barite is also used in radiology for x-rays of the digestive system. When crushed, it is added to mud to form barium mud, which is poured into oil wells during drilling. A rich, white pigment was once made from crushed Barite.
