    Assaying, in chemical analysis, process of determining proportions of metal, particularly precious metal, in ores and metallurgical products. The most important technique, still used today, grew largely out of the experiments of the ancient alchemists and goldsmiths in seeking to find or create precious metals by subjecting base metals and minerals to heat.

    Removing Tarnish from Silver – Compound Interest

     · Silver tarnishes in air to form a black coating of silver sulphide, which has the formula Ag 2 S. The chemical equation for the formation of silver tarnish following reaction with hydrogen sulphide (H 2 S) is as follows:. 2 Ag (s) + H 2 S (g) → Ag 2 S (s) + H 2(g). There's speculation that, in the present day, tarnishing of silver actually occurs more quickly due to the increased amounts ...

    Metal ores are formed in the process of ore genesis, and they are extracted through mining. Extractive metallurgy is the practice of removing valuable metals from an ore and refining the extracted raw metals into a purer form. Hydrometallurgy uses aqueous solutions to extract metals from ores ( leaching ). Pyrometallurgy involves high temperature processes where chemical reactions take place ...
