Ore is a mineral aggregate mined from an ore body from which useful components (elements, compounds, or minerals) can be extracted under existing technical and economic conditions. Ores are formed in various metallogenesis processes. Ores formed under different metallogenesis or at different stages of metallogenesis have different characteristics.

An ore deposit is an economically significant accumulation of minerals within a host rock. [9] This is distinct from a mineral resource in that it is a mineral deposit occurring in high enough concentration to be economically viable. [4] An ore deposit is one occurrence of a particular ore type. [10] Most ore deposits are named according to their location, or after a discoverer (e.g. …

Classification of Minerals. Minerals can be classified according to their economic value and their specific uses. When a mineral contains a useful amount of a particular element, such as iron, it is classified as an ore. Ores are naturally occurring rocks that contain valuable minerals in sufficient concentrations to make extraction profitable.
