Bauxite My rock family Bauxite is a sedimentary rock A sedimentary rock is a rock that is made up of compacted and compressed sediment (dirt, sand, rocks, fossil, debris),the bottom layers begin to compact and cement together to create a hard layer of rock, this occurs due to the intense pressure of the growing layers,the ore found inside

Bauxite ALS

2017-2-1 Bauxite is the world’s principal source of aluminium and can vary from a very soft earth to a very hard rock. It can occur as red-yellow compacted earth (both friable and re-cemented), small red round pebbles (pisolites), or large pale (pink, white, buff) hard stones (see below left). Physical forms of bauxite Pisolitic Pisolitic Earthy Hard rock

Bauxite is a sedimentary rock which is the world's main source for aluminum. Let's get into the bauxite composition. Bauxite mainly consists of the aluminum gibbsite, boehmite, diaspora, and many ores. Bauxite was discovered in 1821 by a French geologist Pierre Berthier.

Bauxite an overview ScienceDirect Topics

Bauxite is a mixed hydroxide of aluminum, silicium, iron, titanium and other metals. Bauxite is firstly transformed in alumina (pure aluminum oxide, Al2 O 3) via caustic soda treatment and separation from other metals, and subsequent precipitation and calcinations. Then molten aluminum is obtained from alumina through an electrolytic process

Bauxite: The principal ore of aluminum. Geology

Physical Properties of Bauxite. Bauxite is typically a soft material with a hardness of only 1 to 3 on the Mohs scale.It is white to gray to reddish brown with a pisolitic structure, earthy luster and a low specific gravity of between 2.0 and 2.5. These properties are useful for identifying bauxite; however, they have nothing to do with bauxite

Uses of Bauxite Bauxite Formula Principal

The two types of Bauxites ores found in the Earth’s surface are: 1. Laterite (silicate bauxite) 2. Karstic (carbonate bauxite) Bauxites vary physically from region to region according to their geographical origin. Some of the deposits are soft and easy to crush while some are dense, hard and pisolite or pea like granular rocks.
