·the gold minerals before they report to cyclone overflow On the overflow stream from the hydrocyclones the IPJs/BCCs are used to scavenge any fine gold minerals; again they treat the entire stream In this case it is a single pass opportunity to recover the gold minerals O/F U/F CONC TAIL TAIL CONC Fig 4 Gravity Concentration Flowsheet
The large particles are diverted back into the crusher and the fine particles will undergo a spiral gravity separation process 5 Spiral gravity separation The gravity separation feed range is approximately 30% solid concentration Process water is used to assist the separation process
·Both types are important in gold processing The number of valid gold minerals presently stands at about 30 However most of these are rare and of little or no consequence in gold processing Table A contains minerals known to occur in signifi cant amounts in gold ores and which therefore probably have at least some impact on processing In

2 ·Copper processing is a complicated process that begins with mining of the ore less than 1% copper and ends with sheets of % pure copper called cathodes which will ultimately be made into products for everyday most common types of ore copper oxide and copper sulfide undergo two different processes hydrometallurgy and pyrometallurgy
·Principles of Process Support in Mineral Resource and Mineral Reserve Estimation 2 Principles of Process Support Work 2 These Practice Guidelines for Mineral Processing PGMP were prepared by the Sub Committee on Practice copper molybdenum and gold from a primarily copper deposit nickel and Platinum Group Metals PGMs from a
·This paper aims to summarize these studies and present a systematic review of the mineral processing of gold ores with a particular focus on alternative leaching reagents to cyanide that can facilitate cleaner extraction Chemical oxidation is currently the most common degradation process in gold plants while greener biological
·Gold can be liberated from refractory ores by roasting high or low pressure oxidation bacterial oxidation and chemical oxidation [12] but these processes often imply environmental problems excessive capital requirements high operating and maintenance costs or the need of highly trained operating ozonation process has been
·Flotation is a process used for treating gold ores that have a lot of sulfide minerals that float easily In this method the minerals with the gold in them are separated from the waste rock gangue by sticking to air bubbles and floating to the surface
·Stage 3 hashing 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
·The gold extraction method mainly depends on the chemical composition of the gold ore the mineral composition the gold particle size of the gold and the requirements of the finished product Gravity separation flotation magnetic separation cyanidation these different extraction methods can maximize gold recovery
·The ability to quantify this variability and link it to mineral processing performance is one of the primary goals of process mineralogy to recover non ferrous metals and gold from sulfide
