02 Affecting factors of gold ore flotation. Gold mine flotation is a complex process that requires careful optimization of various parameters, including reagent dosage, pH level, slurry density, and flotation time. The specific conditions and reagents used may vary depending on the characteristics of the ore and the required gold recovery rate.
