Molybdenum is a soft, lustrous silver grey flaky metal (easily confused with graphite) commonly associated in porphyry copper deposits as a by-product. Molybdenite (MoS2) is the natural mineral sulphide form of the metal.

A quarter of all world molybdenum consumption is used for stainless steel applications - the addition of molybdenum strongly improves the corrosion resistance of stainless steels in a wide variety of environments.

Gold is a heavy, soft, ductile, malleable metal.

This precious metal is used in jewellery, plating, electronics, dentistry and in the chemical industry.

Tin is a silver-white metal which is soft, highly ductile and malleable, and valued for its non-toxicity, resistance to corrosion, and its ready ability to alloy, solder and coat other metals.

Tungsten is a grey-white hard, brittle metal, with a high melting point (3,410C), and always occurs as an oxide in nature.

Bismuth is a brittle metal which often occurs in very small quantities within ores of other metals such as gold, silver, lead, zinc and tungsten.   Unlike many heavy metals, Bismuth has a low toxicity and is often used as replacement for lead particularly in cosmetics (including lipstick) and in medical procedures.

Silver is a soft white lustrous transition metal, it has the highest electrical and thermal conductivity of any metal and occurs in minerals and in free form. This metal is used in coins, jewelry, tableware, photography, and in mirrors.
