Graphite: Mineral information, data and localities.

Named "plumbago" in 1739 by Magnus von Bromell, but in a different sense than previous authors such as Agricola and Conrad Gesner. Also called "molybdaena", but "molybdaena" was shown to represent two species, molybdenite and graphite - as known today, in 1781 by Carl Wilhelm Scheele. Named graphite in 1789 by Abraham Gottlob Werner from the Greek "graphein", "to write".

Remote sensing (geology) - Wikipedia

Remote sensing in geology is remote sensing used in the geological sciences as a data acquisition method complementary to field observation, because it allows mapping of geological characteristics of regions without physical contact with the areas being explored. About one-fourth of the Earth''s total surface area is exposed land where information is ready to be extracted from detailed earth ...

Aragonite: Mineral information, data and localities.

Aragonite Group. The Ca analogue of strontianite. The principal member of the Aragonite Group, aragonite is the second most common polymorph of natural calcium carbonate (the most common is calcite) is significantly less widespread and abundant than calcite and is formed under a much narrower range of physiochemical conditions.

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 ...

6 Potential Environmental Effects of Uranium Mining ...

Although 90-95 percent of the uranium in the ore is extracted during processing (thus reducing uranium concentrations by at least an order of magnitude), most of the uranium decay products (e.g., 230 Th, 226 Ra, 222 Rn), which may comprise the majority of the total radioactivity of the ore, stay in the tailings (Hebel et al., 1978, Van Metre ...

Mineral processing - Wikipedia

Dewatering is an important process in mineral processing. The purpose of dewatering is to remove water absorbed by the particles which increases the pulp density. This is done for a number of reasons, specifically, to enable ore handling and concentrates to be transported easily, allow further processing to occur and to dispose of the gangue.

Clay - Wikipedia

Clay is a type of fine-grained natural soil material containing clay minerals. Clays develop plasticity when wet, due to a molecular film of water surrounding the clay particles, but become hard, brittle and non–plastic upon drying or firing. Most pure clay minerals are white or light-coloured, but natural clays show a variety of colours from impurities, such as a reddish or brownish colour ...
