Floating is a commonly used and important mineral method. Graphite has good natural floating. Basically, all graphite can be purified by floating methods. In order to protect graphite scales, most of the graphite flotation uses multiple sections of processes. Graphite flotation collecting agents are generally used for kerosene, with a dosage of 100 to 200g/t. The foaming agent is generally used with pine or butad ether, and the amount is 50 to 250g/t.
The value and application of large scales graphite are much larger than fine scale graphite, and once it is destroyed, it cannot be recovered. Large scales that protect graphite in graphite are issues that cannot be ignored during the mining process. Because graphite has good natural floating, the floating method can increase the graphics of graphite to 80%to 90%, or even about 95%. The biggest advantage of this method is one of the minimum energy consumption and reagent consumption in all purification schemes. However, the compounds of silicate minerals and potassium, calcium, sodium, magnesium, aluminum and other elements that are mixed in graphite scales and potassium, calcium, sodium, magnesium, aluminum, etc. Essence Therefore, the flotation method is only a primary means of graphite purification. If you want to obtain high carbon graphite with more than 99%of the carbon content, you must use other methods to purify.
2023-04-21Flake graphite is widely used in high-grade refractory materials and coatings in the metallurgy industry. It is like fish phosphorus, belongs to hexagonal crystal system, and has a layered structure. Below, we will provide a detailed explanation of the key points to pay attention to when processing refractory materials with flake graphite.
How to avoid the corrosion of the equipment on the equipment, thereby reducing equipment investment and maintenance costs, and improving production efficiency and profits is a problem that each chemical enterprise always needs to solve. Many products are resistant to corrosion but not high temperature, but scales graphite has both advantages. The following editors will introduce the problem of the device corrosion in detail how to solve the equipment of the scales:1. Excellent thermal conductivity. Scales graphite also has good thermal conductivity. It is the only non -metallic material with a thermal conductivity higher than the metal. The thermal conductivity coefficient is 2 times that of carbon steel and 7 times that of stainless steel. Therefore, it is suitable for heat transfer equipment.2. Excellent corrosion resistance. Various types of carbon and graphite have excellent corrosion resistance to all concentrations of hydrochloric acid, phosphate, and hydrofluoric acid, includin2023-05-15How to solve the corrosion of the device in the scale graphite?
