Alumina

Some alumina is still produced by melting bauxite in an electric furnace, in a process devised for the abrasives industry early in the 20th century, but most is now extracted from bauxite through the Bayer process, which was developed for the aluminum industry in 1888.In the Bayer process bauxite is crushed, mixed in a solution of sodium hydroxide, and seeded with crystals to precipitate Get price

The Best Baking Powder

Baking powder is a mix of baking soda (or another carbon-dioxide producing chemical), a powdered acid such as cream of tartar, and a starch to keep the chemicals dry.

Chapter 2. Production and Processing of Aluminum

Bauxite occurs mainly in the tropics and in some Mediterranean countries. Today, the main mining locations are in Latin America, Australia, India, and Africa. Bauxite is a weathered rock containing two forms of hydrated aluminum oxide, either mostly a monohydrate AlO(OH) in caustic bauxite, or mostly a trihydrate Al(OH) 3 in lateric bauxite. Get price

Azurite: The blue gem material, ore of copper, and pigment.

Geologic Occurrence. Azurite is a secondary mineral that usually forms when carbon-dioxide-laden waters descend into the Earth and react with subsurface copper ores. The carbonic acid of these waters dissolves small amounts of copper from the ore. The dissolved copper is transported with the water until it reaches a new geochemical environment. Get price
