High purity quartz sand is a kind of quartz sand with SiO 2 content higher than 99.9%, which is white powder with no discoloration and low impurity content. High purity quartz sand has high temperature resistance, excellent chemical properties, excellent electrical insulation and transparency, etc. It is an irreplaceable mineral raw material for high-tech industry….
Fodamon engineer has accumulated many years’experience in sand and stone crushing and sand making industry, and summarized the following knowledge about sand making for your reference. What kinds of rocks are there in nature?Natural rocks are divided into three types: the first is magmatic rocks (igneous rocks), which are formed by magmatic eruption and are…
Fodamon engineer has accumulated many years’experience in sand and stone crushing and sand making industry, and summarized the following knowledge about sand making for your reference. What are the main advantages of dry process? The main advantages of dry process are as follows:a, The moisture content of manufactured sand is low, generally less than 2%….
The floatability of copper oxide ores is generally worse than that of copper sulfide ores, and is greatly influenced by the existing form of copper in minerals and gangue composition. For example, when copper is in the form of carbonate (malachite, blue copper ore), the flotability is relatively good, while the flotability of silicate (silica…
Machined sand is relative to natural sand such as river sand. Natural sand is mainly attacked by natural forces, such as river sand, sea sand, mountain sand and so on. Machine-made sand refers to rock particles with particle size less than 4.75 mm made by mechanical crushing and screening after soil removal. Making machine-made sand…
Flotation is a method of wet separation of grinded solid minerals according to the different physical and chemical properties of mineral surface. The flotation method commonly used in industry is essentially froth flotation. It is characterized by the addition of chemical additives to the pulp and the introduction of air. After strong stirring, bubbles are…
In road construction projects, stone is an important building material and is widely used. In the project, commonly used stone materials include granite, gneiss, diorite, sandstone, limestone and so on. In general, natural rock must be processed to meet the requirements of the project. According to the geometrical dimensions of stone products, the stone products…
The process of extracting gold from cyanide pulp or solution by activated carbon adsorption includes CIP method, CIL method and CIC method. Fodamon engineers summarize the following steps:A. Gold is adsorbed and leached from cyanide pulp or solution with activated carbon to produce gold-bearing carbon.B. The desorption treatment of gold-loaded carbon makes gold on carbon…
Dry magnetic separator is suitable for magnetic separation of magnetite, pyrrhotite, roasted ore, ilmenite and other materials with particle size less than 30 mm. It is also used for iron removal of coal, non-metallic ore, building materials and other materials. Thickness of feeding layer. It has a great relationship with the particle size of the…
Due to the impact of grinding minerals, the mechanical friction energy of the grinding materials and the energy released when the materials are broken, the temperature of the ball mill is too high, and the high temperature in summer, the working environment is even as high as forty or fifty degrees. In this way, the…
