v good performance safety equipment apatite flotation

Another design of aflotation cellwhich applies ultrasound during theflotationprocess has been developed by Vargas-Hernández et al. (2002).The design consists of a Denver cell (Koh and Schwarz, 2006) equipped with ultrasonic capabilities of performing ultrasound-assistedflotationexperiments.This cell is universally accepted as a standard cell for laboratoryflotationexperiments.
