What You Need To Know About Laboratory Flotation Testing

Before the test begins, it is necessary to clarify every stage of the flotation experiment, including ore sample processing, flotation machine preparation, reagent preparation and addition sequence, and detailed experimental condition setting. Design a reasonable mineral testing process to systematically determine the optimal flotation conditions.

Flotation Kinetics: Mass Recovery vs Entrainment

Flotation batch and rate tests measure this performance and express it as a set of numbers which are the flotation kinetics of Fast and Slow fraction and rate. Flotation kinetics are therefore a numerical description of the ore's flotation behavior and also a simplified numerical description of the ore's mineralogy.
