Ore is natural rock or sediment that contains one or more valuable minerals, typically including metals, concentrated above background levels, and that is economically viable to mine and process. [1][2][3] The grade of ore refers to the concentration of the desired material it contains.

Jun 12, 2023 · 1 Crush, grind, and classify the raw oxidized gold ore (containing copper). 2 Give the ore an alkaline treatment. 3 Add certain proportion of chelating agent and sodium cyanide to inhibit the leaching of copper and the selective leaching of gold.

Uranium ore deposits are economically recoverable concentrations of uranium within Earth's crust. Uranium is one of the most common elements in Earth's crust, being 40 times more common than silver and 500 times more common than gold. [1] . It can be found almost everywhere in rock, soil, rivers, and oceans. [2] .

Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel — 98% of the mined iron ore is used to make steel. [2]

Most metallic ore minerals are native elements, sulfides, sulfosalts, oxides, or hydroxides. Ore deposits are highly variable in nature and origin. The most important kinds of ore deposits are magmatic, hydrothermal, and sedimentary. Earth gives us many mineralogical resources, also called mineral commodities.
