Magnetite is strongly magnetic, so low-intensity magnetic drum separators (drum LIMS) are widely used in processing magnetite ores. . The annualized plant results demonstrated that an iron ore concentrate containing 68.4% Fe could be produced using the flow sheet from run-of-mine ore containing 29.1% Fe, at a mass.

Optimization of Magnetite Carrier Precipitation Process for .

results of a series of laboratory tests done to optimize the process. The parameters we optimized included (1) magnetite concentration used to precipitate plutonium from solution, (2) formation of magnetite (in situ or ex situ), (3) processing pH, and (4) temperature and mixing time of the carrier precipitation. We also studied.
