The case of concentration plant of iron ores

1 froth flotation fundamental principles(a) from table 1, the ratio of concentration can be calculated as f/c = 100/10 = 10. if only assays are available, the ratio of concentration equals (20 0.1)/(2.09 0.1) = 10 so, for each 10 tons of feed, the plant would produce 1 ton of concentrate.
