Ore - Wikipedia
Ore is natural rock or sediment that contains one or more valuable minerals concentrated above background levels, typically containing metals, that can be mined, treated and sold at a profit. [1][2][3] The grade of ore refers to the concentration of the desired material it contains.
9 Ore Deposits and Economic Minerals – Mineralogy
Ore deposits and ore minerals fall into several main commodity groups: metallic and semimetallic elements, nonmetallic elements, gems, construction and manufacturing materials, fertilizer and chemical minerals, and energy resources (table below).

2022年8月28日 · 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.
Ore | Processing, Extraction & Refining | Britannica
Ore, a natural aggregation of one or more minerals that can be mined, processed, and sold at a profit. An older definition restricted usage of the word ore to metallic mineral deposits, but the term has expanded in some instances to include nonmetallics.
Ore types, including rock and alteration data, are used to deter-mine operational parameters for each part of the process. The assessment of ore types, and the assignment of every rock in a mine to one of them, is thus ubiquitous in mining and vital throughout the value chain.
