Istanbul Ores Minerals Suppliers and Manufacturers

We supply Bismuth is a white, crystalline, brittle metal with a pinkish tinge. Bismuth is the most diamagnetic of all metals, and the thermal conductivity is lower than any metal except mercury. It has a high electrical resistance, and has the highest Hall effect of any metal (that is, the greatest increase in electrical resistance when placed in a magnetic field). Bismuth is stable to oxygen and water but dissolves in concentrated nitric air. All bismuth salts form insoluble compounds when put into water. Applications Bismuth metal is used in the manufacture of low melting solders and fusible alloys as well as low toxicity bird shot and fishing sinkers. Certain bismuth compounds are also manufactured and used as pharmaceuticals. Industry makes use of bismuth compounds as catalysts in manifacturing acrylonitrile, the starting material for synthetic fibers and rubbers. Bismuth is sometimes used in the production of shot and shotguns. Bismuth in the environment The most important ores of bismuth are bismuthimite and bismite. Bismuth occurs naturally as the metal itself and is found as crystals in the sulphides ores of nickel, cobalt, silver and tin. Bismuth is mainly produced as a by-product from lead and copper smelting, especially in USA. The chief areas where it is mined are Bolivia, Peru', Japan, Mexico and Canada, but only to the extent of 3.000 tonnes per year. There is no reliable estimate of how much bismuth is available to be mined, but it seems unlikely than there will ever be a shortage of this metal.

Bleaching clay, also known as activated clay or bleaching earth, is a type of clay that is used in various industrial processes, particularly in the purification and refining of edible oils and fats. It is commonly used to remove impurities, pigments, and other contaminants from these oils and fats, thereby improving their quality and appearance. Bleaching clay works by adsorbing the impurities and coloring substances, resulting in a cleaner and clearer final product. Bleaching clay is typically composed of various clay minerals, such as montmorillonite, bentonite, and attapulgite, which have high adsorption capacities. These clays are activated to increase their surface area and adsorptive properties, making them more effective in the removal of impurities. The activation process usually involves treatment with various chemicals or thermal processes to enhance their bleaching capabilities.
