Selective flocculation of kaolin: 11 am and at pH8, Ca2 + was added to the pulp kaolin, Mg2 + and other alkaline earth metal ions can be observed selectively flocculating the iron-titanium impurities, and then selectively flocculated by a polyelectrolyte weak anion. The process requires that the slurry concentration be less than 20%, so there must be a large amount of water to be removed in the subsequent operations, and the residual flocculant also has an impact on the quality of the final product. Selective flocculation of kaolin with high-molecular flocculant, the kaolin particles flocculate to the bottom, and the iron-titanium impurities are reddish brown in the suspension in the upper part due to the fine particles, and the upper suspension can be removed. Most of the iron-titanium impurities are removed and processed by other operations (such as magnetic separation) to obtain high-quality kaolin. Suzhou Kaolin Company has achieved good indicators by adopting a new process of selective flocculation. The use of selective flocculation and high gradient magnetic separation to treat kaolin also obtained satisfactory indicators.
Molybdenum can increase steel`s corrosion resistance in the acid-based solutions and liquid metals, thus improve its wear resistance, hardenability, weldability, and heat resistance. As an element which easy to form carbides, molybdenum can effectively avoid oxidation during steel making process, and it can be used alone or mix with other alloy element to achieve the best performance.
A pure molybdenum rod is a cylindrical bar made entirely of molybdenum, a chemical element with the symbol Mo and atomic number 42. Molybdenum is a refractory metal known for its high melting point, excellent thermal conductivity, and resistance to corrosion. Pure molybdenum rods are commonly used in various applications, including the manufacturing of electrodes, heating elements, and high-temperature furnaces. They are also utilized in the aerospace, defense, and medical industries due to their exceptional mechanical and thermal properties.
