Iron ore Wikipedia

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.

Comminution in mining

Comminution is the most energy intensive process stage in the mining industry. It accounts for up to 40 percent of the total energy used in mineral processing operations. While the head grades are constantly declining, more sustainable technologies and solutions are required to process hard, variable and low-grade ore bodies.

ASARCO Mining

A number of mine plans based on different metal prices can be developed to help the mine better respond to changing market conditions. When the price of copper is high, lower-grade ore can be cost-effectively mined along with the better grade ore. When the price is low, the mining operations can focus on the higher grade ores.
