is bauxite found in hard or soft rock

Bauxite - My rock family

Formation. 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). After rocks, sand, dirt and other sediment is eroded and weathered through air, wind or waterways, all this sediment begins to pile up layer after layer.

Bauxite Deposits - an overview ScienceDirect Topics

Bauxite deposits are mainly found in a wide belt around the Equator. It lies relatively close to the surface and is normally strip-mined. Bauxite contains typically 40–60% aluminium oxide (alumina) in the form of several hydrous alumina phases (gibbsite, Al(OH) 3 , boehmite (AlOOH) and diaspore (ALOOH), and with smaller amounts of iron, silicon and titanium compounds as well as other trace impurities.

Bauxite - Wikipedia

The lateritic bauxites are found mostly in the countries of the tropics. They were formed by lateritization of various silicate rocks such as granite, gneiss, basalt, syenite, and shale. In comparison with the iron-rich laterites, the formation of bauxites depends

Bauxite - ALS

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.

Bauxite ore Britannica

Bauxite, rock largely composed of a mixture of hydrous aluminum oxides. Bauxite is the principal ore of aluminum. Bauxites vary physically according to the origin and geologic history of their deposits: some deposits are soft, easily crushed, and structureless; some are hard, dense, and pisolitic,

Bauxite: The aluminum mineral bauxite

Bauxite is not a mineral, but rather a group of aluminum oxides. The term is generally used to describe the economically important mixture of these minerals, which form a mass of the individually classified members of Gibbsite, Boehmite, and Diaspore.Bauxite does not make aesthetic or interesting specimens as far as collectors are concerned, but it holds importance as being the primary ore of ...

Laterite - Wikipedia

Laterite is both a soil and a rock type rich in iron and aluminum and is commonly considered to have formed in hot and wet tropical areas. Nearly all laterites are of rusty-red coloration, because of high iron oxide content. They develop by intensive and prolonged weathering of the underlying parent rock.Tropical weathering (laterization) is a prolonged process of chemical weathering which ...

Chemical composition and surface property of

01-11-2003  The crystallinity index was lower for hard kaolin than for soft kaolin. The floatability of hard kaolin was lower than that of soft kaolin. Hard kaolin was the dominant kaolin in bauxite. A new type of collector for hard kaolin was studied in order to selectively separate kaolin from diaspore in bauxite. The surface zeta potential variation of the hard kaolin as a function of pH was almost the same as that of the soft kaolin. The IEP of the hard

Are malignant cancer lumps hard or soft? Do I

If something is rock solid, it means it is confined to a specific area and has not metastasized (spread) to nearby tissue. Still, a common person without lots of "hands-on" experience is hardly qualified to figure out whether what they're feeling is hard or soft.
