pH MODIFIERS Mineral conditioning and pH control can greatly affect flotation performance Most mineral beneficiation processes require some type of pH adjustment to impart ideal separation conditions As mineral feed quality continues to decrease more sophisticated pH modifiers are needed to achieve optimum flotation performancePH Modifiers The role of pH modifier and the dosage affect flotation From test results it was confirmed that sodium silicate and other chemicals can be be used with depressant and dispersant could adjust the pH of pulp Flotation efficiency using pH modifier is better than that using lime in the alkaline conditions pH 95 11
