barium | Uses, Compounds, & Facts | Britannica

Barium minerals are dense (e.g., BaSO 4, 4.5 grams per cubic centimetre; BaO, 5.7 grams per cubic centimetre), a property that was the source of many of their names and of the name of the element itself (from the Greek barys, "heavy").Ironically, metallic barium is comparatively light, only 30 percent denser than aluminum.Its cosmic abundance is estimated as 3.7 atoms (on a scale where the ...

Baryte Mining Process | Equipment | Flow | Cases - JXSC

Baryte is a mineral consisting of barium sulfate (BaSO4). baryte is generally white or colorless and is the main source of barium. The barite group consists of baryte, celestine (strontium sulfate), anglesite (lead sulfate), and anhydrite (calcium sulfate). Baryte and celestine form a solid solution (Ba, Sr)SO4.

Need of refining aluminium and Hoope vs Hall–Héroult processes

In the Hoope's process, as per wiki, there are 3 molten layers: a Cu-Al-Si metal anode, a mix of cryolite and barium fluoride middle layer, and molten Al as the cathode on top. Barium fluoride is much more dense than cryolite. So the layering makes sense if enough barium fluoride is used.
