Bayer process
The Bayer process is the principal industrial means of refining bauxite to produce alumina (aluminium oxide) and was developed by Carl Josef Bayer.Bauxite, the most important ore of aluminium, contains only 30–60% aluminium oxide (Al 2 O 3), the rest being a mixture of silica, various iron oxides, and titanium dioxide. The aluminium oxide must be purified before it can be refined to

Calcium carbonate | CaCO3
Calcium Carbonate is the carbonic salt of calcium (CaCO3). Calcium carbonate is used therapeutically as a phosphate buffer in hemodialysis, as an antacid in gastric hyperacidity for temporary relief of indigestion and heartburn, and as a calcium supplement for preventing and treating osteoporosis.

Calcination
The process of calcination derives its name from the Latin calcinare (to burn lime) due to its most common application, the decomposition of calcium carbonate to calcium oxide and carbon dioxide, in order to create cement.The product of calcination is usually referred to in general as "calcine", regardless of the actual minerals undergoing thermal treatment.

Fineness Modulus
The bigger the fineness modulus is, the more coarse the sand is. The fineness modulus of the sand used in ordinary concrete is within 3.7 ~ 1.6.And if M x is within 3.7 ~ 3.1, it is coarse sand; if M x is within 3.0 ~ 2.3, it is medium sand; if M x is within 2.2 ~ 1.6, it is fine sand; and if M x is within 1.5-0.7, it is superfine sand which should be considered specifically when concrete is

How chalk is made
The main component of chalk is calcium carbonate (CaCO 3 ), a form of limestone. Limestone deposits develop as coccoliths (minute calcareous plates created by the decomposition of plankton skeletons) accumulate, forming sedimentary layers. Plankton, a tiny marine organism, concentrates the calcium found naturally in seawater from .04 percent to

How Sugar Is Processed
The sulfur dioxide rises up through the tower in a process called sulfitation. Gas is added at 120 to 200 pounds per million pounds of juice. Carbonation or alkalization is used to further separate the soluble non-sugar materials from the sugar juice. Carbonation employs calcium carbonate or calcium sulfite to aid in precipitation.

Ammonium Phosphate
An alternative process uses a hemihydrate process which produces calcium sulfate with a half molecule of water (CaSO 4 ½ H2O). This one-step hemihydrate process has the advantage of producing wet process phosphoric acid with a higher phosphate pentoxide (P 2 O 5) concentration and less impurities than the dihydrate process.
