It is obvious that the floor area of hydrocyclone is significantly smaller than that of the spiral classifier. Usually, the hydrocyclone covers an area of only l/30 to l/50 to the spiral classifier. The equipment floor area requirement also limits the application of the spiral classifier to a certain extent. 3. Classification Efficiency.

Existing and New Processes for Beneficiation of Indian Iron ores
Accordingly, iron ores with minimum 45% Fe cannot be rejected or dumped by any means. As the cutoff grade of iron ore is reduced to 45% Fe, the availability of iron ore resources has increased substantially. However, at the same time, Indian iron ore mining industries will have to heavily depend on the advanced beneficiation techniques …
