Mineral Raw Materials are mineral constituents of the earth's crust of economic value. In the most comprehensive sense this includes the so-called "mine output" as well as the output from processing at or near the mines (for instance, the up-grading of ores to concentrates). Primary Materials are marketable products obtained by processing crude minerals (usually up to the first processing stage only).
