English: Entrance to the King Edward Mine Museum with Chickens Getting the tin ore to the surface was only the start of the process of producing the "black tin", an ore concentrate good enough to be smelted to produce ingots of "white tin". The problem was that the ore (cassiterite) does not occur in large pure lumps but is mixed in with other minerals in the vein. To remove this waste material involves a complicated processes of crushing and separation with the aid of water by several different types of machinery. This museum preserves the buildings and machinery which used to perform these operations. It offers a fascinating insight into an industry now vanished from Cornwall and into the means of industrial production in an age before electricity. Well worth a visit.
