Gold. In southern Africa, two x-ray sorters are used to pre-concentrate sulphide gold ore into two different grain size categories. While the input material has an average gold content of less than 0.8 g/t, the sorted product achieves a concentration of more than 4 g/t with an efficiency of approximately 90%. In 2005, Myra Falls produced 912,565t of ore grading 6.1% zinc, 1.2% copper, 51g/t silver and 1.8g/t gold. Its concentrate output contained 48,084t of zinc, 7,640t of copper, 31,750oz of gold and 1.17Moz of silver, giving a cash production cost of US$0.47/lb of zinc.

Aug 26, 2020 The gold ore dressing method. 08-26-20 703 Views icon 1 The gold ore dressing method. Various types of gold ore have different beneficiation methods due to their different properties. However, gravity separation, flotation, amalgamation, cyanidation and recent years resin slurry method, carbon slurry adsorption method, heap leaching method, etc. are commonly used to extract gold. In-situ leaching mining (see the mining background page) has been introduced as the required mining method for those new mines that can physically implement this technology. Saponification, a step of the refining process that leaves the wastewater highly toxic, can be improved through a newly discovered method that eliminates the need for ammonia.
