Hematite is the world's most important ore of iron. Although magnetite contains a higher percentage of iron and is easier to process, hematite is the leading ore because it is more abundant and present in deposits in many parts of the world. Hematite is mined in some of the largest mines in the world.

The type of tailings dam a mining company builds is directly related to the safety of the structure. Engineers have found that tailings dams tend to be safest, i.e. most resistant to failure and collapse, when they are not built on top of or using previously-deposited tailings.However, the safest dams, like downstream dams, are more expensive …

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.

Description. Commonly called fool's gold, pyrite is the Earth's most abundant sulfide mineral. Recognized for its brass-yellow color which resembles that of gold, pyrite is a source of iron and sulfur and is used for the production of sulfuric acid. Some types of pyrite contain enough microscopic gold to warrant mining them as a gold ore.
