Graphite flotation method

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 process flow of carbon material production

The basic process of carbon material production includes: pre-treatment (pre crushing, calcination, or drying) of carbon raw materials, crushing, grinding, and screening grading of carbon raw materials, proportioning of carbon raw materials, addition of molten dehydrated binder and kneading, forming of paste after kneading, and roasting of formed green billets. In order to improve the density and strength of products, high-pressure impregnation and secondary roasting cycle densification treatment are carried out on the roasted billets, The graphitization of roasted products involves mechanical processing of carbon and graphite products.Why are the quality indicators of high-power and ultra-high-power graphite electrodes superior to ordinary power graphite electrodes?The current density of graphite electrodes used in high-power and ultra-high-power electric furnaces significantly increases, resulting in the following problems: (1) due to resistance heat and hot airflow, the temperature

Lubrication of scales graphite

Scale graphite has many functions. Today, the editor focuses on the lubrication effect of scales graphite. As a lubricant, scales graphite is mainly distributed in water, oil or other media to form stable colloidal substances. It can be directly applied to parts that need to be lubricated. Combined with lubricant.The use of scales graphite as a lubricant has the following effects: After using scales graphite powder lubricants in various mechanical operating components, it can reduce friction, fever, burns, etc., and extend the service life of the machine; reduce the loss of friction power and improve work efficiency; Save lubricating oil consumption, many of which can be reduced to about 60%; improve the surface quality of processing parts, and extend the service life of processing parts and appliances; reduce mechanical failures and noise during the operation, and save maintenance costs; add boilers, add boilers, add boilers, add boilers, add boilers, add boilers, add boilers, add bo

Graphite high-temperature purification method

Graphite is one of the substances with the highest melting and boiling points in nature, with a melting point of 3850 ± 50 ℃ and a boiling point of 4500 ℃. However, the boiling points of silicate minerals are all below 2750 ℃ (quartz boiling point), and the boiling point of graphite is much higher than the boiling point of the impurity silicate it contains. This characteristic is the theoretical basis for high-temperature purification of graphite. Fill the graphite powder directly into a graphite crucible and heat it in a purification furnace filled with inert gas and Freon protective gas to 2300-3000 ℃ for a period of time. Impurities in the graphite will overflow, thus achieving the purification of the graphite. The high-temperature method generally uses high carbon graphite containing over 99% carbon purified by flotation or chemical methods as the raw material, which can purify the graphite to 99% 99%. By further improving the process conditions and improving the quality of the cr

Flake graphite processing

Flake graphite is obtained by mining and processing from graphite mines. The types of ore mined are different, and when processing flake graphite, it is also necessary to process it correctly based on the characteristics of the graphite ore. So how should we proceed with the operation? Let's have a simple understanding of flake graphite below.1. Mineral processing method for flake graphite cryptocrystalline graphite.Cryptocrystalline graphite crystals are very small, hence also known as microcrystalline graphite. Graphite particles are usually embedded in clay and difficult to separate. Due to the high grade of the raw ore (usually containing carbon), many graphite mines directly crush and process the extracted ore, selling graphite powder products.2. Mineral processing method for crystalline graphite in flake graphite.The natural floatability of crystalline graphite is good, and it is basically used in China. Due to the particle size of graphite sheets being one of its most important

What are the characteristics of the thermal stability of the film -shaped graphite

Sheet -shaped graphite is a natural ore, with a thin piece or scale, and the aggregate is in the form of soil. It is a hidden crystal. Film graphite has many high -quality physical and chemical characteristics, including good thermal stability. Compared with other products, the thermal stability of film -like graphite has great advantages.Film graphite is one of the most high -temperature -resistant materials at present. Generally, the strength of the material is gradually decreased at high temperature. However, when heating to 2,000 degrees Celsius, the strength of the sheet -shaped graphite is twice the temperature at room temperature.Sheet -shaped graphite has excellent heat shock resistance. When the temperature suddenly changes, the thermal expansion coefficient is small, so it has good thermal stability. When the temperature changes rapidly, cracks will not occur.Sheet -shaped graphite is a material with excellent thermal shock. For graphite electrodes used in electric furnace s

The relationship between graphene and scales graphite

Graphene is stripped from scales graphite materials, composed of two -dimensional crystals composed of carbon atoms, with a thickness of only one layer. Because graphene has excellent performance in optics, electrical, and mechanics. Is graphite related to graphene? Let me analyze the relationship between scales graphite and graphene with everyone:1. The method of extraction of graphene mass production is not obtained from scales graphite, but from carbon -containing gas such as methane and acetylene. Although the word graphite is used in the name, the production of graphene is not mainly from scales graphite. On the contrary, it is obtained from carbon -containing gas such as methane and acetylene. Even the current research method is extracted from the planting plant tree. Now there is a method for extracting graphene from the tea tree.2, scales graphite contains millions of graphene. Graphene is actually in nature.
