Clay mineralsWikipedia

Clay minerals are common weathering products (including weathering of feldspar) and low-temperature hydrothermal alteration products. Clay minerals are very common in soils, in fine-grained sedimentary rocks such as shale, mudstone, and siltstone and in fine-grained metamorphic slate and phyllite.

Clays | Minerals Education Coalition

Clay is an abundant, naturally occurring, fine-grained material composed predominately of hydrous aluminum silicates. Clay is not a single mineral, but a number of minerals. Clays fall into six general categories: kaolin, ball clays, fire clays, bentonite, common clays and Fuller’s earth. Clays are common all over the world.

Environmental Characteristics of Clays and Clay Mineral

Clay minerals have a wide range of particle sizes from 10’s of angstroms to millimeters. (An angstrom is a unit of measure at the scale of atoms.) Thus, clays may be composed of mixtures of finer grained clay minerals and clay-sized crystals of other minerals such as quartz, carbonate, and metal oxides.

USGS Minerals Information: Clays

Six types of clays are mined in the United States: ball clay, bentonite, common clay, fire clay, fuller’s earth, and kaolin. Mineral composition, plasticity, color, absorption qualities, firing characteristics, and clarification properties are a few of the characteristics used to distinguish between the different clay …

Clay Minerals | Clays and Minerals

Definition: Clay minerals are the characteristic minerals of the earths near surface environments. They form in soils and sediments, and by diagenetic and hydrothermal alteration of rocks. Water is essential for clay mineral formation and most clay minerals are described as hydrous alumino silicates.


Mining is the extraction of valuable minerals or other geological materials from the earth, usually from an orebody, lode, vein, seam, reef or placer deposit.These deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.

Division of Geology and Mineral ResourcesClay Materials

The se minerals belong to the clay mineral group distinguished by a layered crystal lattice structure that allows for the exchange of calcium, sodium, potassium, among other ions. This property makes certain clay minerals useful in industrial applications for adsorption, filtration, oil refining, and as additives in paint and paper manufacture.

A large panel of clay systems has to be studied in a consistent way: 10 Ǻ phases (smectites, illites), 14 Ǻ phase (chlorites) and 7 Ǻ phases (kaolinite, berthierine…). Thermodynamic properties of clay minerals, which govern the stability of these minerals in solution, are still poorly understood.

Clay ProcessingUS EPA

11.25 Clay Processing 11.25.1 Process Description1-4 Clay is defined as a natural, earthy, fine-grained material, largely of a group of crystalline hydrous silicate minerals known as clay minerals. Clay minerals are composed mainly of silica, alumina, and water, but they may also contain appreciable quantities of iron, alkalies, and alkaline .

Ohio, and West Virginia, where the clays are mainly underclays associated with coal and suitable for refractory uses. Ball Clay.—The ball clay industry was small, with 6 producers operating 26 mines in 5 States in 1994. Three of the producers were large, diversified firms with widespread foreign and domestic mineral interests.

The one to one clay minerals have alternating silica and alumina sheets; these are the least reactive of the clay minerals, and kaolinite is the most common example. The two to one minerals have layers made up of an alumina sheet sandwiched between two silica sheets.
