Effect of coarse quartz scalping on the reverse cationic
circuit. The silica distribution in the fraction gt; 0,150 mm is 8,6%, while the iron distribution increases in the fraction lt; 0,075 mm. The size distribution of the scalped sample (fraction 2), illustrated in table 3, indicates that the slimes content (lt; 0,009 mm), as expected, is low 2,46%. Table 3.
