The use of power ultrasound in mining L Gaete Garretón in Power Ultrasonics 2015 The flotation process One of the most used processes to concentrate mineral from a mine is flotation To perform a flotation process the mineral is finely ground particle sizes between 50 and 150 μm then the ground mineral is mixed with water in a container called a flotation cell
·Ultrasonic treatment has been widely used in the mineral flotation process due to its advantages in terms of operational simplicity no secondary pollutant formation and safety Currently many studies have reported the effect of ultrasonic treatment on mineral flotation and shown excellent flotation performance In this review the ultrasonic mechanisms are classified
This method based on lasso regularized multinomial logistic regression allows for an in depth understanding of particle flotation behavior as a function of all measured particle characteristics and the joint influences of particle size shape as well as modal and surface compositions can be taken into unprecedented consideration
·Principle of froth flotation The differences in physicochemical surface qualities of distinct minerals are used in froth flotation Differences in surface qualities between the minerals inside the flotation pulp become obvious after reagent treatment and for flotation to occur an air bubble must be able to attach itself to a particle and raise it to the surface
