Diatomite

Diatomaceous earth diatomite is a kind of sedimentary rock with white and yellow color. It consists of fossil skeletons of single-cell algae called diatoms. It accumulates in the sea area. Honeycomb Syria structure is very useful because of its high absorption capacity and surface area. It is also very chemically stable. Its main purpose is to filter. This material of diatomaceous earth is extracted from many countries all over the world. Of the 30 countries in the world, the largest suppliers are the United States, China, Denmark, and Japan.

Diatomaceous earth is a rock consisting of a diatom skeleton, and a unicellular organism is a skeleton composed of silica present in fresh water or salt water. Diatomaceous earth is mainly used for filtration of beverages such as juice and wine, but it is also used as a filler for paints, medicines and environment cleaning technologies. Fluorite is used for the production of hydrofluoric acid used in ceramic, ceramic, optics, electroplating and plastics industry. It is also used for metallurgical processing of bauxite as a flux in open hearth steel furnace, as metal refining and as carbon source for carbon electrode, grinding wheel, electric arc welding machine and toothpaste.

Opals are also formed by diatoms. Diatoms are aquatic organisms like microscopic shells. When they die and form a layer in the bottom of the lake, the bay and the ocean, their shells are made of opal and form "granules" of rock diatomaceous earth. This sedimentary rock is white and opaque and has a texture of white chalky. Diatomaceous earth has fine grain size and very porous nature and has gardening to increase adsorption of water, so it has various industrial uses such as filtration or adsorption. The Australian opal accounts for 95 to 97% of valuable opal supply in the world, South Australia state is considered to account for 80% of world supply. Recent data suggests that valuable opal supplies in the world may have changed. In 2012, the US Geological Survey estimates that Ethiopia opal production is 14,000 kg (31,000 pounds). According to US Geological Survey (2012) data, the Australian opal production was $ 41 million.

According to US Mining's website, registered mines in the Winkelman area are mining the following minerals: copper, gold, lead, silver, zinc, plaster - anhydrous gypsum, asbestos, diatomaceous earth, iron, molybdenum, tungsten, Sulfur, vanadium. These minerals, except for gold and asbestos (whose toxicology is unique, eventually we will talk about gold and asbestos), if there is a sufficiently high concentration in the water it can harm the human body. In addition, the oxidation state of these minerals, in particular the cations of minerals dissolved in water, is very important for the toxicity of minerals. Another important characteristic to remember is the effect of pH on the toxicity of metals.
