heal.abstract	A novel two-stage froth flotation process for the recovery of pure magnesite from low grade ores is described. The process consists of a first-stage, magnesite flotation step where a rougher magnesite concentrate is floated with amine collectors. The first-stage froth concentrate is then repulped in fresh water, and quartenary ammonium salt and fuel oil are added to float the remaining impurities. The results from laboratory batch tests show that a high-grade magnesite concentrate assaying 0. 99-0. 20% SiO//2 and 2. 84-0. 46% CaO can be produced. Regulation of the variables controlling magnesite froth flotation also allows the variation of the ratio %CaO:%SiO//2, between the acceptable limits 0. 32 to 5. 79. This ratio is important to the quality of dead-burned magnesite.	en
