Frequent anomalies often occur in flotation operations. The causes of these phenomena are also complex and often not entirely due to one factor. For the convenience of reference, various common anomalies, causes and adjustment methods are listed. See Table 1. Table 1 Abnormal phenomena commonly found in flotation operations, causes and main adjustment methods CNC Abrasive Sand Line Machine Cnc Abrasive Sand Line Machine,Cnc Belt Grinder,Cnc Belt Grinding Machine,Cnc Belt Sander Grinder Taizhou Jiangzhou CNC Machine Tool Manufacturing Co.,Ltd , https://www.jzcncmachine.com Anomalies cause Main adjustment method Low concentrate grade 1. Mineral composition and ore oxidation, muddy degree change 2. Concentrate operation mass fraction, large concentrate output 3. Inflatable excess 4. Overdose, reduced selectivity 5. Concentrate scraping 1. Pharmacy, process 2. Reduce the mass fraction, reduce the amount of output 3. Reduce the amount of aeration 4. Reduce the amount of the agent 5. Reduce the amount of scraping Low recovery 1. Mineral composition and ore oxidation, muddy degree change 2. Grinding fineness 3. Improper dosage 4. Production overload, flotation time less than 5. Middle mine circulation increased, unstable flotation process 1. Pharmacy, process 2. Improve the fineness of grinding grade 3. Adjust the agent 4. Reduce the amount of ore given 5. Reduce the amount of foam sprayed Slurry overflow 1. Flotation quality score is small 2. Grader overflow increases 3. Flotation machine accident, slurry circulation is not good 4. Foaming agent excess 5. Pulp gate is too high 6. Return amount (middle mine) increase 1. Reduce the amount of water supply 2. Adjust the grinding and grading operation 3. Repair the flotation machine or clean the pipeline 4. Reduce or stop the drug 5. Adjust the gate 6. Reduce the amount of medium ore Pulp surface drop 1. Flotation mass fraction becomes larger 2. Flotation granularity is coarse 3. Flotation machine's stirring force decreases, gas tube is blocked or shedding 4. The ore grade increases 5. The amount of foaming agent is less than 6. Motor, pipeline, pump accident, Less pulp 1. Reduce the amount of or increase the amount of water 2. Adjust the grinding and classification operation 3. Repair the flotation machine 4. Add the medicine 5. Increase the amount 6. Repair, clear Foamy sticky 1. The ore in the ore increases 2. The pH value of the pulp rises 3. The foaming agent is excessive 4. The lubricating oil is mixed in the slurry 5. The drug station accident 6. The amount of scraping is too large for each operation 1. Adjust the agent 2. Reduce the amount of the regulator 3. Reduce the dosage 4. Add or stop adding the pine oil and analyze the cause 5. Check the dosage of the agent 6. Reduce the amount of scraping
