An ore deposit is a welldefined mineral deposit that has been tested and found to be of sufficient size, grade, and accessibility to be extracted (i.e. mined) and processed at a profit at a specific time. Thus, the size and grade of an ore deposit changes as the economic conditions change. Ore refers to industrial minerals as well as metals.
No fully satisfactory term has yet emerged to describe the processing of minerals, which is also called "ore dressing", "mineral dressing", "mineral engineering" and, in the University of London degree course "mineral technology".
