metal ores (<1% copper, <1g/ton gold, < % nickel) previously considered uneconomical, became feasible with introduction of heap leaching technologies (Marsden, 2009). In consideration of ore types, a generalized diagram showing the applicable ore beneficiation technologies for oxide and sulphide ores versus ore grade is given in Figure 2.
Gold ores are typically amenable to sensorbased ore sorting to some degree, and this is usually accomplished with XRT or laser sensors, or a combination of both. A twostep sorting flowsheet consisting of an XRT rougher plus a laser scavenger (or alternatively, a laser rougher and an XRT scavenger) has already proved an optimal recovery ...
To the untrained eye, gold ore may look like rock with copper tones flowing within it. However, professional prospectors know how to recognize gold ore within a multitude of minerals. Recognizing the look and the location of gold ore is easier if you know how to find lode and placer deposits.
