Abstract. Few of the metals or minerals required by modern civilisation are mined naturally pure and ready to use. Instead they occur in complex aggregates of up to twenty different minerals of which only one or two will be of value. There are some two hundred of these ‘value’ minerals amoung the several thousand minerals that go to form
