During gold ore processing Steadily rising gold prices are also stimulating the need for gold process mineralogy due to the increasing demand for and production of the yellow metal At SGS Lakefield Research gold process mineralogy studies are conducted routinely on all types of gold ores and mill products to assist in a wide variety.
Load the solid gold ore into your crucible then load the furnace with charcoal Light the charcoal and let it ash over Set the crucible directly on the charcoal Load more charcoal around the crucible Turn the hair dryer on low to force air into the chamber below the charcoal If the temperature fails to get high enough to melt your ore turn.
Crushing the ore can free the gold and allow recovery by gravity based methods In fact its very common that the gold in hard rock ores will range in the 30 to 200 mesh size range with most of the gold in the lower end of that range The tried and true method for testing these ores in the field is hand crushing and panning.

Samples of rock from within the pit or from underground are sent to the SGS laboratory in Waihi to determine gold content The data generated from assaying is used to map out which areas are suitable to process as ore and which areas are waste material to be used to build the waste rock embankment or to be used as backfill underground.
Sensor based ore particle sorting can be used to pre concentrate ROM ore feed SAG Mill scats and low grade or waste stockpiles Plant throughput increase reduced operating costs and mine optimization should be considered in evaluating sorting as well as increased recovery in flotation and leach circuits.
The hashing stage corresponding to metal extraction and recovery stages is a little more complex for gold ores as the optimal process flowsheet selection choice is heavily dependent on a good understanding of two fundamental geometallurgical parameters the gold mineralogical associations and the gold particle size and liberation.
