Depending on the orientation of the host magnetite these can be reticulated, forming a "cloth texture," or lie at about 60° to each other. These lamellae can subsequently be oxidized to ilmenite. This process is further advanced in larger, first generation lamellae that appear darker in color than the magnetite (gray in Fig. 6).

 · That's because magnetite ore has fewer impurities than hematite ore; in this way, the elevated cost of processing magnetite ore can be balanced out. Magnetite ore is currently mined in Minnesota and Michigan in the US, as well as in taconite deposits in Eastern Canada. A major mining site in Michigan is the Marquette Range.

 · The crushing process of magnetite often adopts a continuous flow of two-stage and one closed-circuit crushing . 1 The raw magnetite ore is sent to the coarse crusher ( jaw crusher) by the vibrating feeder, and then sent to the fine crusher ( cone crusher or hammer crusher ). 2 After fine crushing, the ore is sent to the screening machine.

The present invention relates to a process to treat magnetite ore containing less than 15 wt% of silica on total ore, the process containing a step of (froth) flotating in the presence of a collector composition that contains 80 to 100 wt% of at least one alkylethermonoamine, less than 20 wt% alkyletherdiamine, all wt% based on total weight of all amine …
