tin processing - Mining and concentrating | Britannica
tin processing - tin processing - Mining and concentrating: Vein deposits, such as those in Bolivia and the United Kingdom, usually occur in granite formations and are recovered by conventional underground hard-rock mining techniques. In deep mines, primary crushing equipment is usually located underground in order to reduce the ore to a manageable size before transportation to the surface.
