2019-2-25 In industrial flotation, there are many kinds of metal ions in the pulp. These unavoidable ions have a great influence on the flotation behaviour of minerals, especially the oxide minerals (James and Healy, 1972; Li et al., 1982). Some metal ions can activate mineral flotation. However, some

2015-7-8 In feldspar processing, flotation beneficiation tailings that containing high ratio of titanium minerals emerge at a considerable amount as a result of beneficiation of feldspar reserves with high TiO2 content due to required specifications by global feldspar market. Recovery of titanium minerals from these tailings which can be evaluated as alternative TiO2 resources is an important research
Lead hydroxyl compounds are known as rutile flotation of the traditional activated component, but the optimum pH range for flotation is 2–3 using styryl phosphoric acid (SPA) as collector, without lead hydroxyl compounds in slurry solution. In this study, Bi3+ ions as a novel activator was investigated. The results revealed that the presence of Bi3+ ions increased the surface potential, due

As SPA dosage increased, the flotation recovery of rutile promoted clearly and quickly. The maximum recovery of 90% was
2014-10-5 Rutile is one of the favored minerals for the production of titanium dioxide white pigment, dominantly through the chloride manufacturing process [1, 2].However, majority of rutile ores belong to refractory ores, while flotation is one of the most efficient methods to solve the problem [].With the flotation development, many effective collectors are successfully applied in the oxide ores.
Flotation in the Minerals Industry Some Observations. Recent trends in flotation technology are briefly reviewed. These show that considerable development has been made as the operators, suppliers and technologists have responded to the challenges of the industry. Most of these advances have been based on empirical and phenomenological methods.
