The purpose of the pH adjuster test is to find the most suitable pH adjuster and its amount to make the floating minerals have good selectivity and floatability.
For most ores, the type of conditioner and pH
can be determined by actual production experience . However, the pH
value is related to the composition of the ore material and the nature of the floating water, so the pH
test is still required . At the time of the test, on the basis of the optimum grinding fineness, other flotation conditions were fixed, and only the type and amount of the adjusting agent were tested. The test results are plotted as a graph, the grade and recovery rate are plotted on the ordinate, and the pH
adjuster is used as the abscissa. According to the curve, a comprehensive analysis is performed to find the optimum dosage of the pH-
feeding agent. If you have determined the type and pH
value of the pH
adjuster based on the production experience , you can determine the amount of the pH
adjuster by adding the pH
adjuster to the slurry of the flotation machine in batches. After stirring for a certain period of time, determine the slurry. The pH
value, such as the pH of the
pulp, does not reach the required value, and a pH
adjuster can be added until the desired pH
is reached, and finally the total The amount is the required amount. Due to the interaction between the chemicals, sometimes the change in the amount of other agents will also change the pH of the
slurry . In this case, the calibration test can be performed after the various conditions are tested, or the pH
adjuster can be used. The influential agents were tested in a multi-factor combination. Ordinary Slag Cleaner
