SF-0.37 SF-0.7 Self Aspirating Flotation Machine for Pilot Ore Beneficiation The SF-0.37 and SF-0.7 are the compact models of the SF series self-aspirating flotation machine. With 0.37–0.7 m³ cells, they are the natural choice for laboratory-pilot tests and small ore-beneficiation lines, letting you prove a flowsheet before scaling up. Suited to pilot and small-scale work Bench and pilot flotation testwork. Small-tonnage beneficiation lines. Trial runs on new ore or reagent
