7/8/2017· In addition, Table 3 shows the achieved sulfur contents in the iron ore concentrate after the flotation test and the mass recovery (yield) of each pre-test. The results vary greatly in both mass recovery and sulfur content. The mass recovery was in the range of 85.4  % to 97.6  %. The sulfur content was between 0.26  % and 0.91  %.
