Milling produces a uranium oxide concentrate, which is shipped from the mill. In the milling process, uranium is extracted from the crushed and ground-up ore by leaching, in which either a strong acid or a strong alkaline solution is used to dissolve the uranium oxide. The uranium oxide is then precipitated and removed from the solution.

Surface mining. Surface mining is exactly what the word says - digging rocks out from the surface, forming a hole or pit. In South Africa, this method is used to mine for iron, copper, chromium, manganese, phosphate and coal. Surface mining is also known as open pit or open cast mining. An open pit coal mine.
Iron oxide, also known as oxide red, is an inorganic substance that is red or deep red amorphous powder.
