Generally speaking, in addition to the mechanical method, screening also includes the method of fluid particles grading. Mechanical screening is most used for screening incompact materials with a particles size between 100 ~ 0.05mm. The screening efficiency of materials with a particle size below that range is very low due to its condensation bond, so […]

Manganese ores are mainly used in iron and steel industries and the ratio of the ore consumption to the iron and steel output ranges from 3.6% to 4% in China. If China produces 120 million tons of iron and steel, then 4.8 million tons of manganese ores are needed. In recent years, the export of […]

Tungsten is a high-melting or refractory metal among metallurgical and metallic materials. This metal and its alloys form one of the extremely important functional materials for modern industry, national defence and high and new technologies. They are widely used in many fields such as space, atomic energy, shipbuilding, automobile, electrical, electronic and chemical industries. Tungsten-bearing […]
