· The methods used for the extraction of iron from haematite are not single, mainly include the froth flotation method, magnetic separation method, gravity separation method and roasting magnetic separation method. [email protected] . 0086 15311826765. Language.

· Based on the results, two flow sheets comprising gravity, magnetic separation and flotation, were used to recover chromite values. A chromite concentrate of 45.0% Cr 2 O 3 with a Cr:Fe ratio of 2.3 can be produced from the tailing analyzing 17.0% Cr 2 O 3 and Cr:Fe ratio of 0.49.

Gravity separation, relies on the difference in density of the mineral and the gangue. This technology can be applied to primary recovery, preconcentration, and final upgrading, as well as recycling and soil washing.Hazen''s gravity concentration facilities are among the finest in the world.

· Wolfram ore coarse concentrate magnetic separation process: before separation, the material is crushed to-3 mm by roll crushers, then they are screened into three levels which are 0.83 ~ 3 mm, 0.2 ~ 0.83 mm and 0 ~ 0.2 mm, and finally you can get wolframite concentrate by magnetic classification beneficiation.

· In the end, the final qualified products still need to be obtained by magnetic separation, flotation, and calcination. 2.Kaolin Magnetic Separation Almost all kaolin raw ore contains a small amount of iron minerals, generally 0.5% -3%, mainly including colored impurities such as magnetite, ilmenite, siderite, and pyrite.

Xinhai Solution: The plant originally used weak magnetic-strong magnetic separation process.The production practice showed that this process failed to obtain final qualified concentrate and the recovery rate was low. Therefore, Xinhai decided to carry out technical renovation, adopted gravity separation-magnetic separation-floating stage grinding process.After roughing, concentration ...
