gold processing Mining and concentrating Britannica

The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade ( 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then piled into heaps for extraction by cyanidation (see below).

Elemental gold is an excellent conductor of electricity and heat surpassed only by the other members of group 1B copper and silver. Gold usually forms compounds (and complexes) by giving up either one of three of its valence electrons. It is commonly alloyed with other metals as in jewelry in proportions that yield desired hardiness and
