Effect Of Hydroxamic Acid Polymers On Reverse Flotation Of

The effect of hydroxamic acid starch (HAS) and hydroxamic acid polyacrylamide (HPAM) on the flotation of diaspore and kaolinite was investigated by flotation test. It is found that HAS depresses diaspore but activates kaolinite in acidic pulp, while HPAM activates both diaspore and kaolinite in the pH range of 2.010.5. The measurement of zeta potential shows that both HAS and HPAM can ...

Significance Of Particle Aggregation In The Reverse

Jul 01, 2015 The reverse flotation of kaolinite from bauxite using amine is achieved at pH 45 as shown in Fig. 6 (Hu et al., 2005, Marino, 2012). Unfortunately, the nature of the reverse flotation of kaolinite is not well understood. Only recently have details of the kaolinite surface been established (Gupta and Miller, 2010, Liu et

Analysis Of Reverse Cationic Iron Ore Fines Flotation

Dec 01, 2018 Flotation experiments. For reverse cationic flotation, the pre-determined quantity of iron sample was transferred to the laboratory Denver flotation cell and water was added to the cell to maintain the pulp density at the level of 20% solids by weight. Flotation tests were carried out in an Agitair-LA500 Machine using 2.3 L capacity cell.
