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. There are four main types of.
In older books it is common to find minerals classified, as in Table 2.1, according to the use that is made of the metal or mineral extracted from the ore. Table 2.2 contains some of the minerals that are mined for copper. We see that this metal is extracted from various types of sulfides and sulfosalts, as well as from sulfates,.
