GOLD BENEFICIATION.pptx - MINERAL BENEFICIATION

Gold in its purest form, is a bright, slightly reddish yellow, dense, soft malleable and ductile metal. It is one of the least reactive chemical elements and is solid under standard conditions. Gold is resistance to corrosion. Gold occurs principally as a native metal, usually alloyed to a greater or lesser extent with silver (as electrum), or sometimes with mercury (as an amalgam).
