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. …

Magmatic ore minerals, also known as primary ore minerals, are minerals that form directly from the crystallization of magma or from the hydrothermal fluids associated with magmatic activity. Magmatic ore minerals are often associated with igneous rocks, such as intrusive rocks (plutonic rocks) and extrusive rocks (volcanic rocks), and they can be an …

Extraction of Metals. What is a Metal Ore?. A solid element or compound which occurs naturally in the Earth's crust is called a mineral.A mineral which contains a high enough percentage of a metal for economic extraction is called a metal ore. Economic extraction means that the cost of getting the metal out of the ore is sufficiently less than the amount of money made by selling the metal.

In the simplest terms, ore is a naturally occurring solid material from which a metal or valuable mineral can be extracted profitably. An ore deposit could contain lead, gold, copper, or any other metal or mineral that has economic value. The key point is that for a material to be considered ore, it must be economically viable to extract its components.
