A mining company owns two mines. These mines produce an ore that can be graded into two classes regular grade and low grade. The company must produce at least 410 tons of regulargrade and 530 tons of lowgrade ore per week. The first mine produces 6 tons of regulargrade and 16 tons of lowgrade ore per hour.

In March, more than 507,000 tons of iron ore pellets were shipped from the DuluthSuperior Port, according to Jayson Hron, Duluth Seaway Port Authority director of communications and marketing.
Oct 23, 2013 A typical wind turbine contains more than 8,000 different components, many of which are made from steel, cast iron, and concrete. One such component are magnets made from neodymium and dysprosium, rare earth minerals mined almost exclusively in China, which controls 95 percent of the worlds supply of rare earth minerals.
Jan 29, 2019 The Philippines has maintained its position as a top nickel ore producer and exporter for approximately a decade. In 2016, the country produced about 347,000 metric tons, but production has since dropped to about 230,000 metric tons. The decline is directly attributed to the closure of 23 mines by the Ministry of Environment and Natural Resources.
Goldstrike mine in northeastern Nevada is one of the largest gold mines in the world. In 2016, the mine produced 1.1 million ounces of gold. Only two other operationsthe Grasberg mine in Indonesia and the Muruntau mine in Uzbekistanproduced more..

While steel products require energy to be produced, they can also offer savings over the life cycle of the product, sometimes greater than the energy used during their production. For example, over 20 years, a threemegawatt wind turbine can deliver 80 times more energy than is used in the production and maintenance of the material used.7
The statewise data is yet to be compiled. The country has produced 210 million tonnes of iron ore in 201718, said an official of the Federation of Indian Mineral Industries FIMI. India had produced more than 200 million tonnes in 201011 at the height of a mineral boom before the clampdown on illegal mining in the country
More details will be discussed later on the intermediate carbide compound and stepbystep reaction. Since the melting point of FeCr alloy will be lower than the melting point of Fe or Cr 15301475oC based on the Cr content, it is possible to separate metal from slag with proper chemical compositions at temperature less than 1600oC.
By 1860, southern Ohioans had established sixtynine iron furnaces, producing more than 100,000 tons of iron annually, across Gallia, Hocking, Jackson, Lawrence, Scioto, and Vinton Counties. The manufacturers sent much of the iron up and down the Ohio River to Cincinnati and Pittsburgh, allowing southern Ohioans to prosper.
