The rock is mixed with water and ground in rotating mills until it is as fine as powder. 4. Separation The iron ore is separated from the taconite using magnetism. The remaining rock is waste material and is dumped into tailings basins. The taconite powder with the iron in it is called concentrate. 5. Pellets
Sep 18, 2019· Iron ore sintering is a type of powder metallurgy used to pre-treat iron before using it in manufacturing applications. Sintering involves heating iron powder to partially, but not completely, melt the iron particles. The exact process used and additional elements involved vary, with some methods using gas or electricity in addition to heat.
Increasing iron ore demand, coupled with the depletion of high-grade hematite ores in the United States, after World War II led to development of lower-grade iron ore sources, principally the utilization of magnetite and taconite. Iron-ore mining methods vary by the type of ore being mined.
