WebThus the Dowfroth family offers a wide spectrum of frother capability ranging from DF-200 giving a high R value and low K to DF—1012 giving a high K value with a potentially lower R value. The particular R and K value needed in a given application depends on the nature of the engineering layout and operation along with the ore type, etc ... WebGood recoveries were also obtained for Dowfroth 400 and Flotanol C07, whereas Dowfroth 200 and MIBC failed to float any quartz. From experiments in which a given feed material were tested at two different particle size distributions it was found that highest recoveries were obtained for the finer feed. Chemical analysis of the floated products ...
