Chat Online· Lime is the most economical and commonly used reagent for pH control in flotation. •. Ca 2 ions in lime can enhance depression of minerals and flotation selectivity in a variety of ores. •. For talc- and clay-rich ores Ca 2 ions can be detrimental and other pH modifiers are preferred. •.
