Table 1 Abnormal phenomena commonly found in flotation operations, causes and main adjustment methods
Anomalies | cause | Main adjustment method |
Low concentrate grade | 1. Mineral composition and changes in ore oxidation and muddy degree 2. The concentration of concentrate operation is large, and the output of coarse concentrate is large. 3. Inflated excess 4. Overdose, reduced selectivity 5. Large amount of concentrate scraping | 1. Pharmacy, process 2. Reduce the quality score and reduce the output 3. Reduce the amount of inflation 4. Reduce the dosage of the drug 5. Reduce the amount of scraping |
Low recovery | 1. Mineral composition and changes in ore oxidation and muddy degree 2. Grinding fineness 3. Improper dosage 4. The production volume is overloaded and the flotation time is insufficient. 5. The amount of medium ore circulation increases, and the flotation process is unstable. | 1. Pharmacy, process 2. Improve the fineness of grinding grade 3. Adjust the pharmacy 4. Reduce the amount of minerals 5. Reduce the amount of foam sprayed |
Slurry overflow | 1. Flotation quality score is small 2. Grader overflow increases 3. Flotation machine accident, poor slurry circulation 4. Foaming agent overdose 5. The slurry gate is raised too high 6. The amount of return (middle mine) increases | 1. Reduce the amount of water supplied 2. Adjust the grinding classification operation 3. Repair the flotation machine or clean the pipeline 4. Reduce or stop taking drugs 5. Adjustment gate 6. Reduce the amount of medium ore |
Pulp surface drop | 1. The flotation quality score becomes larger 2. Flotation granularity is coarse 3. The stirring force of the flotation machine drops, the inflation tube is blocked or falls off. 4. The original ore grade is raised 5. Insufficient amount of foaming agent 6. Motor, pipeline, pump accidents, less pulp | 1. Reduce the amount of minerals or water 2. Adjust the grinding classification operation 3. Repair flotation machine 4. Adding pharmacy 5. Increase the dosage 6. Repair, dredge |
Foamy sticky | 1. Increased slime in ore 2. The pulp pH rises 3. Foaming agent overdose 4. Mixing lubricating oil into the slurry 5. Medicine station accident 6. The amount of scraping is too large for each job | Adjust the medicament 2. Reduce the amount of regulator 3. Reduce the amount 4. Add or stop adding pine oil and analyze the cause 5. Check the dosage 6. Reduce the amount of scraping |
Ion exchange resin is a crucial component used in glass fiber reinforced plastic pressure tanks to effectively remove both anions and cations present in water, ultimately softening the water.
The ion exchange resin works through a process known as ion exchange, where it replaces undesired ions in the water with more desirable ones. This resin is typically made up of small, porous beads that contain charged functional groups.
When water passes through the pressure tank containing the ion exchange resin, the resin beads attract and retain the unwanted anions and cations present in the water. These unwanted ions, such as calcium, magnesium, iron, and sulfates, are exchanged with more desirable ions like sodium or potassium.
The exchange process occurs as the water flows through the resin bed, allowing the resin beads to selectively trap the unwanted ions and release the desired ions. This effectively removes the minerals responsible for water hardness and replaces them with softer ions, resulting in softened water.
Softened water offers various benefits, including preventing scale buildup in pipes and appliances, improving the efficiency of water heaters, reducing soap scum and residue on surfaces, and providing better lathering and cleaning capabilities.
