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.

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 of the electrodes increases, resulting in an increase in the thermal expansion of the electrodes and joints, and an increase in the oxidation consumption of the electrodes; (2) The temperature difference between the center of the electrode and the outer circle of the electrode increases, and the thermal stress caused by the temperature difference also increases accordingly. The electrode is prone to cracking and surface peeling; (3) After the power of the electric furnace is increased, the electromagnetic force increases, causing severe vibration and increasing the probability of electrode breakage.Therefore, the physical and chemical properties of high-power and ultra-high-power graphite electrodes must be superior to ordinary power graphite electrodes, such as low

Advantages and disadvantages of graphite purification methods

Flotation method is one of the conventional mineral purification methods that consumes the least energy and reagents, and has the lowest cost. This is the biggest advantage of flotation method for purifying graphite. However, using flotation to purify graphite can only achieve a limited increase in its grade. For flake graphite, using multi-stage grinding not only cannot completely dissociate its monomer, but also is not conducive to protecting the large scale of graphite. Therefore, using flotation to further improve graphite grade is neither economical nor scientific. To obtain high carbon graphite with a carbon content of over 99%, chemical methods must be used to purify the graphite.(1) Alkali acid purification method. The carbon content of graphite purified by alkaline acid method can reach over 99%, which has the characteristics of low one-time investment, high product grade, and strong process adaptability. Moreover, it also has the advantages of conventional equipment and stro
