Abstract
A brief literature review on flotation of calcium-bearing minerals is given. It is found that flotation activity of a collector is connected with physisorption of the collector in particle-bubble attachment. The tests prove that physisorption decrease reduces recovery and increases the useful component content /yield ratio in the concentrate. The found correlation is a framework for new approaches to quality improvement of flotation concentrates. The method proposed to select compositions of collectors can enhance selectivity of extraction of useful minerals.
