gold processing, preparation of the ore for use in various products For thousands of years the word gold has connoted something of beauty or value These images are derived from two properties of gold, its colour and its chemical stabilityThe colour of gold is due to the electronic structure of the gold atom, which absorbs electromagnetic radiation with typical high grade gold ore sample tested at Gekko Systems Pty Ltd As mass yield is increased the gold recovery increases Batch units such as BCC’s are limited to mass flow to concentrate of less than 005% and accordingly cannot generally achieve the high recovery levels required for a gravity only circuitA New Age Gold Plant Flowsheet Gekko S
