Scale Growth in the Dewatering of Iron Ore - sapub

The influence of different flocculants, used in copper concentration, on the filtration capacity has been published earlier for the ceramic filter medium[9] and has shown that the filter medium is indeed affected by different chemicals which cause blinding. Similar studies on iron ore have not been found by the authors.

    Effects of Surfactants on the Improvement of Sludge

     · The flocculated sludge was poured into a Buchner funnel for filtration under a vacuum pressure of 0.06 MPa for 15 min or until the vacuum cannot be maintained in <15 min. The filterability of the sludge was measured by the specific resistance of the sludge. DS was determined by the following equation given as
