Very impure tin can be refined by electrolysis to very high purity.-snip-Did you know that an alloy of 80% gold 20% tin melts at around 280°C(536° F.) this would easily allow casting into rubber moulds! Has anyone tried this? I've got the tin if you've got the gold! apparently this alloy is used as a special solder and has a slight green colour.

There are two economic sources of lithium; brines and hard rock ores. The majority of the global lithium production, greater than 60%, is produced from brines while lithium ores accounted for the remaining production (Ebensperger et al., 2005).Table 1 summarises the world's major lithium producers from ores and brines, and the total reserves. The lithium …
