Energy and Environmental Profile of the U.S. Mining Industry 4
Table 4-3 shows the estimated energy requirements for a surface iron mine in the U.S. The iron mine operates over a 22-year lifetime with a 110 million-ton output at the end of its life. The mine runs 364 days per year with two 8.00 hour shifts per day, which gives it a daily production rate of 13,699 tons per day.

The Costs of Mining | The Breakthrough Institute
The mine will be 40 miles from the Fort McDermitt Paiute and Shoshone Tribes (FMPST) reservation and is the largest lithium resource in the US. Lithium Americas, the company in charge of the project, is leaching lithium from the clay deposits with sulfuric acid. Sulfuric acid attacks the ore, separating the lithium which dissolves into the acid.

Iron Ore | Geoscience Australia
Iron (Fe) is a metallic element that constitutes 5.6% by weight of the Earth's crust and is the fourth most abundant element in the crust. Iron ores are rocks from which metallic iron can be economically extracted. The principal iron ores contain hematite (Fe 2 O 3) and magnetite (Fe 3 O 4 ). Hematite is an iron oxide mineral.
