4. Flotation is the most widely used separation method. The factors affecting flotation can be divided into ore properties, flotation machine and operating conditions. Flotation machine is the most important factor affecting the flotation index. It can be said that the quality of flotation machine determines the flotation index. In the practice of mineral processing proction, the correct selection of flotation machine is concive to improving the flotation index and saving energy consumption, so the selection of flotation machine is particularly important. How much do you know about the selection rules of flotation machine? The following small series for you to introce the flotation machine selection rules
1. The selection of flotation machine should be determined according to the properties of flotation ore. The floatability, particle size composition, grade, pH value and density of ore are all factors affecting the selection of flotation machine. The better the floatability of useful minerals is, the worse the floatability of gangue minerals is, which indicates that the ore is easy to be selected. Therefore, flotation machines with low aeration intensity can be selected, such as self suction mechanical stirring flotation machine; If the floatability of useful minerals is not good, the flotation machine with high aeration intensity should be selected, such as aeration mechanical stirring flotation machine. Generally, the particle size of ore particles is coarse, so the flotation machine with shallow bottom and high stirring intensity should be selected, such as SF flotation machine; The particle size of ore particles is generally fine, so the flotation machine suitable for fine particle flotation, such as flotation column, should be selected. When the grade of ore is low, it is suitable to choose self suction mechanical stirring flotation machine or pneumatic mechanical stirring flotation machine; When the ore grade is low, it is suitable to select the flotation column with large enrichment. The pulp pH of different ores is different. When selecting flotation machine, the material of flotation machine should be required according to the specific pulp pH value
2. The selection of flotation machine should be decided according to the scale of concentrator. Practice and research show that the flotation cost per ton of ore can be effectively reced by using a larger type of flotation machine, so the larger type of flotation machine is preferred in large concentrators. For medium or small concentrators, medium or small size flotation machines are generally used. The specific specifications should be determined according to technical and economic analysis
3. The selection of flotation machine should be based on the flotation operation. Roughing and sweeping operations are mainly aimed at improving the recovery rate of useful minerals. Therefore, the foam layer should be thinner. Generally, the self absorption mechanical stirring flotation machine with small charge and the inflatable and small pneumatic mechanical flotation machine are generally used. For the selected operation, the main purpose is to improve the grade of useful minerals. Therefore, the foam layer should be thicker. Generally, the aeration mechanical stirring flotation machine or flotation column is widely used.
4. The selection of flotation machine should be based on the equipment quality of flotation machine manufacturer and the supply of spare parts. When selecting the flotation machine, we should have a detailed understanding of the major manufacturers of the flotation machine, especially the reputation of the manufacturers. The right choice of flotation machine manufacturers is equivalent to the right choice of flotation machine, which should be given high attention
Jinpeng flotation machine has been used in many concentrators and has been widely praised by customers. In addition, we can choose the most suitable flotation machine model and specification for you according to your specific needs. Buy flotation machine, find Jinpeng mining machine!
