Resources supplied by nature, such as ore deposits, mineral deposits, oil reserves, gas deposits, and timber stands, are natural resources or wasting assets. Natural resources represent inventories of raw materials that can be consumed (exhausted) through extraction or removal from their natural setting (e.g. removing oil from the ground).

Energy and Environmental Profile of the U.S. Mining Industry 126.96.36.199 Underground Mining Underground mines are established in areas with promising ore deposits. Iron ore deposits may lie deep underground. A shaft must be dug from the surface and an elevator or hoist must be installed.
This concentrated ore is mixed with limestone (CaCO 3) and Coke and fed into the blast furnace from the top. It is in the blast furnace that extraction of iron occurs. The extraction of iron from its ore is a long and subdued process, that helps in separating the useful components from the …
A free-blast method for extracting ore from an ore vein deposit wherein the vein is extracted by causing the ore comprised between the rock walls bordering the vein to spall into fragments. The ore fragments are recuperated as by aspiration and subsequently processed to retrieve the precious mineral.

Obtaining resources from ores is as simple as mining them (this is not the case for iron and gold ores, which must be smelted). Coal, diamond, emerald, and nether quartz ores drop 1 unit corresponding raw materials. Redstone ore drops 4-5 redstone dust, and lapis lazuli ore drops 4-8 lapis lazuli. Note this can be increased greatly with fortune.
An ore is a natural occurrence of rock or sediment that contains sufficient minerals with economically important elements, typically metals, that can be economically extracted from the deposit. The ores are extracted at a profit from the earth through mining; they are then refined (often via smelting) to extract the valuable element or elements.
Chromium processing, preparation of the ore for use in various products. Chromium (Cr) is a brilliant, hard, refractory metal that melts at 1,857 °C (3,375 °F) and boils at 2,672 °C (4,842 °F). In the pure state it is resistant to ordinary corrosion, resulting in its application as an electroplated
The mining and processing of mineral ores results in the production of large quantities of residual wastes that are for the most part earth- or rock-like in nature.
