Six types of clays are mined in the United States ball clay, bentonite, common clay, fire clay, fullers 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 types. Major domestic markets for these clays are as.

    Introduction To Clay Minerals Amp Soils

    Clay minerals are layer silicates that are formed usually as products of chemical weathering of other silicate minerals at the earths surface. They are found most often in shales, the most common type of sedimentary rock. In cool, dry, or temperate climates, clay minerals are fairly stable and are an important component of soil.

    Exploitation of mineral wealth at a rapid rate shall naturally deplete our good quality deposits. The ever rising demands shall compel miners to carry on the extraction from increasingly lower and lower grade of deposits which possess a poorer percentage of the metal.

    We may never reach an end as matter is indestructible. Most of the metals we require are present in highly dispersed state in the soil, the rocks and the trash or wastes we discard. With a sophisticated technology we can fulfill most of our requirements from these sources, But the overall cost could be I heavy, causing the metals to become more and more costly.

    Most of our mineral deposits occur as a complex mixture of a number of mineral elements. After removal of top soil and rocks we dig out the desired mineral leaving behind others which are often left in the open as waste materials. Extraction of one element usually scatters and wastes a number of other elements, many of which are in short supply.
