OSTI.GOV Journal Article Simulation of extraction process of scandium separation from iron and titaniumOSTI.Nov 29, 2013 A process for leaching a value metal from a titaniferous ore material comprising the step of leaching the ore material at atmospheric pressure with a lixiviant comprising magnesium chloride and hydrochloric acid is disclosed. Iron and titanium are leached into solution. Iron in the ferric state may be separated from titanium in solution using extraction with alkyl ketone.Jun 16, 2011 Removing iron by oxidation and filtration. In cases of iron levels higher than 0.3 ppm, sequestration is not possible, and therefore the iron must be physically removed from the water.May 22, 2016 The heavy-media separation process, or HMS, employing ferrous media, usually ferrosilicon andor magnetite, is the most generally used process for sink-float separations. A stable medium over the range of specific gravities from 1.25 to 3.40 can be maintained within close limits and is cleaned and recovered by magnetic means.zinc, cadmium and iron, which otherwise interfere with the process. Figure 1 shows the overall process flowsheet into which the new separation process is inserted.
Magnetic Separation Process Of Iron Ore Ftm Machinery
Besides, the separation machines are devide into the dry and wet magnetic separation. Generally, iron ore with an iron content of 35 can increase iron content by 20 after magnetic separation. Such a combined process method, the ore utilization rate can reach 90.
