Lead and Zinc Lead and zinc ores are usually found together with gold and silver. A lead-zinc ore may also contain lead sulfide, zinc sulfide, iron sulfide, iron carbonate, and quartz. When zinc and lead sulfides are present in profitable amounts they are regarded as ore minerals. The remaining rock and minerals are called gangue.

[clarification needed] Electroless nickel plating uses hypophosphite as the reducer while plating of other metals like silver, gold and copper, typically use low-molecular-weight aldehydes. A major benefit of this approach over electroplating is that the power sources and plating baths are not needed, reducing the cost of production.

What causes plating to "flake" or loose adhesion and what can be done to ensure proper adhesion of a plated layer? Adhesion is clearly paramount in both decorative and functional finishes. In situations where the adhesion of a plated deposit fails, the loss of adhesion is often blamed on the deposit itself.
Silver also provides good lubricity and solderability. Gold: Although plating gold onto aluminum is a somewhat expensive process, it will not form an oxide on the substrate surface in most cases. Gold's biocompatibility makes it an excellent choice for plating medical devices made from aluminum alloys.
Gold plating is long lasting over a base of gold. For example 18kt gold plated over 14kt gold lasts longer than 18kt yellow gold over sterling silver. So whatever metal is being used for the base in gold plating, it plays a significant role in how long the plating treatment will last.
