The flotation equipment is mainly a flotation machine and other equipment for implementing the flotation process. After stirring inflatable ore slurry, the mineral particles adhering bubbles, the bubbles rise under the action of the various flotation agents to form mineralized foam layer is scraped or scraper overflow, this series are in the floating flotation process Completed in the machine.
The flotation machine is mostly made up of multiple tanks connected in series. Black colored flotation machine for sorting metals, non-metals may also be used, such as: coal fluorite, talc sorting. Today, Zhenbei Industry and Trade Xiaobian focuses on the specific method of fluorite flotation machine in the flotation of fluorite mine.
The flotation machine drives the impeller to rotate by the electric motor V-belt drive, and generates centrifugal force to form a negative pressure. On the one hand, the air is mixed with the slurry, and on the one hand, the slurry is mixed with the medicine, and the foam is refined to make the mineral bond foam. , floating to the pulp surface to form mineralized foam. Adjust the height of the shutter and control the liquid level so that the useful foam is scraped off by the scraper.
When the flotation machine floats fluorite, oleic acid can be used as a collector . In addition to oleic acid, hydrocarbon sulfate esters, sulfonates and the like can also be used as collector. Adjusting agent for sodium silicate, sodium meta-phosphates, lignosulfonates, dextrin, etc., the main problem is the separation of the flotation fluorite quartz, calcite, and barite and sulphide ore, the separation method is as follows:
1. Sorting of fluorite and quartz. Adjusted with sodium carbonate slurry PH value 8-9. Water suppression quartz glass, fluorite with a fatty acid collector. The amount of water glass should be controlled. If the amount is too large, fluorite will be inhibited. In order to increase the selectivity of water glass and to enhance the inhibition of water glass, polyvalent metal ions are often added.
2. Separation of fluorite from barite and calcite. Generally, oleic acid floats out of fluorite. Floating dissecting small amount of aluminum salt activated fluorite fluorite, calcite and barite inhibition plus dextrin. For the more complex fluorite ore containing calcite, limestone and dolomite , it is better to use the baking gum and lignosulfonate to resist the gangue minerals.
3. Sorting of fluorite and barite. Generally, fluorite and barite are mixed and floated, and then separated. Concentrate mixture separation may be employed two methods: one is to use dextrin or tannin inhibiting barite, fluorite floating oil with iron salts; second is to use a hydrocarbon sulfate flotation barite, fluorite will remain in Inside the slot.
4. Fluorite ore containing sulfide ore. Generally, the xanthate collector is used to float the sulfide ore, and the fatty acid is added to the fluorite. If the flotation ore is not floated, a small amount of sulfide ore inhibitor may be added to suppress residual sulfide ore to prevent it from being selected into the fluorite concentrate.
Anti-static Separator Paper
Anti-static separator paper is also called isolation paper, anti-sticking paper and silicone oil paper. It is a kind of anti-sticking paper which can prevent the prepreg from sticking and protect the preg from pollution. Removal paper is made of paper coated with anti-sticking material. Its type should be distinguished according to the difference of material, thickness, elongation and one-sided and two-sided.
Thickness: 50±5um
Feature: Anti-static and smooth in two-sided
Application: Separator function between membrane
