Explanation:
An ore is an experience of rock or sediment that comprises sufficient minerals with economically valuable elements, typically metals, that can be economically derived from the deposit. The ores are obtained from the earth through mining; they are then polished (often via smelting) to extract the important element or elements.A metal is a material (an element, compound, or alloy) that is typically hard, opaque, shiny, and has good electrical and thermal conductivity.
