PHILIPPINE SILVER PRODUCTION
Pure silver is nearly white, lustrous, soft, very ductile, malleable, it is an excellent conductor of heat and electricity. It is not a chemically active metal, but it is attacked by nitric acid (forming the nitrate) and by hot concentrated sulfuric acid. It has the highest electrical conductivity of all metals, but its greater cost has prevented it from being widely used for electrical purposes.
Silver was used widely as far back as prehistoric times. The old Sanskrit word 'argunas', meaning 'shining brightly', mutated into the Latin word 'argentum' from which the symbol 'Ag' is derived. The word 'silver' is of obscure Anglo-Saxon origin
