Garbage can also refer specifically to food waste, as in a garbage disposal; the two are sometimes collected separately.
melting is what you do to a material that is metal, without flux. What you would do with pure PMs. Smelting is what is done to remove impurities from gold and reduce/oxidize other materials out. Since gold does not oxidize borax affects lighter elements that oxidize and rise to the surface.hat you would do with pure PMs. Smelting is what is done to remove impurities from gold and reduce/oxidize other materials out.

Borax is a mild alkaline body, and as a detergent is probably equivalent to a slight excess of caustic soda. It occurs in body wastes, in artificial fertilizers, as a by-product of natural decay, and very notably in detergents. Nitrogen and phosphorus occur in the effluent from waste treatment plants, for they are present in human wastes and in detergents, and in dissolved form are little affected by standard treatment processes.
