The actual flotation process is a complex, multi-factor coupling separation process. The bubble size is synergistically affected by the frother, collector, slurry properties, mechanical energy input, and air flow rate in the flotation cell. The effect of multi-factor coupling on the bubble size should attract sufficient attention.

UK). The barium salt may be barium chloride (hydrated or anhydrous); but barium bromide dihydrate, which is more soluble in water than barium chloride dihydrate [9], is usually preferable for preparing barium monoaluminate gel precursors. Acetates that can form alkaline solutions, ammo-nium acetate for instance, are known [10] to gel

A barium swallow gives a clear picture of the back of your throat and the tube that leads to your stomach (your oesophagus) as you are swallowing. A barium meal shows your stomach and the upper part of your bowel after you have swallowed the barium. Often a barium meal x-ray is taken straight after the barium swallow.

Then, terpenic oil was added to the cell with agitating for 3 min. Subsequently, air flow was introduced into the cell at a rate of 1.6 L/min, in the process of which bubbles occurred with sizes of 5–10 mm. After a certain flotation time, the froth products were automatically collected by a scraper blade with a speed of 60 times per min.

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.
