An alternative method for concentrating iron ores by flotation has been to reverse the separation and float the siliceous gangue minerals from the iron oxides by employing cationic collectors. The application of such reagents to iron ores has been described by Kirby and Gillson in United States Patents Nos. 2,217,684 and 2,221,485.

Flotation is widely used in gold processing. In China, 80% rock gold is processed by flotation. Flotation process maximizes the enrichment of gold into sulfide minerals. The tailings can be directly discharged. Flotation in gold mine has low beneficiation cost. Molybdenum Dressing Production Line

The dominant flotation process currently used for processing of siliceous phosphates in Central Florida is the Crago "Double Float" process (Giesekke, 1985; Zhang et al., 1997).The simplified flotation flowsheet is given in Fig. 1.In this process, after desliming and sizing, the ore is conditioned with fatty acids and fuel oil at a pH of 9.0–9.5.

[Process Introduction] There are mainly several methods of gold tailings reprocessing: 1. The iron recovery from gold tailings can adopts common processing technology such as gravity separation, magnetic separation, flotation, roasting magnetic separation and their combined processing technology.

Weathered manganese oxide ore often contains a large amount of slime and fine ore, and the washing and gravity separation method is adopted in production. The raw ore is washed and the slime is removed, after which some of the obtained ore can be used as a finished ore,and some need to be re-selected by jiggers and shaking tables.

PHOSPHATE ROCK (SIC 1475) The term "phosphate rock" includes phosphatized limestones, sandstones, shales, and igneous rocks which do not have a definite chemical composition. The major phosphorus minerals of most phosphate rock are in the apatite group and can be represented by the generalized formula Ca5_(POj»).3 - (F, Cl, OH).

The phosphate rock pulp, generally —28 mesh, is reagentized at high pulp density with the usual reagents involved in phosphate rock flotation, such as fuel oil and tall oil. Stated simply, in the reagentized pulp the quartz gangue is wetted by water and the oiled phosphate rock is not.

The fatty acid flotation of a difficult-to-float igneous phosphate ore (26.2% P 2 O 5, 15.4% Fe 2 O 3) was investigated through batch flotation tests in the presence of soda ash.The poor flotation of this otherwise high quality ore was attributed to very high concentrations of calcium and sulfate ions (about 1000 and 2000 mg/L, respectively) found in process water, which indicated that the ...
