Gold ore whose types of deposits are diverse and complex is the mineral assemblage of gold. With features of chalcophile affinity and high melting point, the gold ore includes conglomerate type, porphyry type, quartz vein type and volcanic rock type, etc.
Ore processing plant means that extracts and purifies some elements in the raw ore through a series of complex ore beneficiation flow and professional beneficiation equipment. The refined concentrate powder is mainly used in metallurgy and industry base.
The 200t/h granite crushing plant in Russia uses HPT220 hydraulic cone crusher as the core crushing equipment
Gravity separation is the main beneficiation method of chrome ore, and the equipment is jigger, shaking table, spiral classifier, centrifugal concentrator and spiral chute, etc. Sometimes it will also use weak magnetic separation or strong magnetic separa

Sulphides require very fine grinding for maximum extraction then are returned to circuit Gangue carries some gold that is easily recovered at coarse mesh Sulphides such as copper or zinc etc are present which can be recovered and sold at a profit for specific metal content by shipping direct to the smelter
Processing Gold from Sulfide Ores 4 replies J JRC 3 years ago JRC 3 years ago We are trying to process gold from arsenopyrite and chalcopyrite ore Our XRF indicated that there was a high concentration of gold along with a variety of minerals We have tried various methods of refining without much luck due to all of the other minerals
Extract sulfide ore deposits from the ground and place in to the crusher to mince ore from 5 to 50 micrometers Crushing begins the separation process by preparing the ore to be floated in water First the ore is crushed using a gyratory crusher to reduce the ore to 6inch diameter pieces
In the past ten years or so there has been a renewed interest worldwide in the processing of refractory gold ores The Archean province of Western Australia contains both numerous and major gold deposits and has a long history in the development and practise of treating refractory ores eg Blaskett and Woodcock 1953 Depletion of
Aug 22 2018 · In this video we show the process of smelting down sulfiderich gold concentrates to end up with a gold button Through roasting the sulfur is driven off in turn converting the metallic
135 Heap Leaching of Nickel Sulfide Ore An alternative to intensifying the rate of leaching of concentrates is to heap leach the whole ore This has the significant advantage of eliminating the concentration of the sulfides which is the step that has the lowest recovery on route from ore to metal Nickel sulfide ores are processed by heap leaching in Sotkama eastern Finland Talvivaara 2011
In the case of Goldstrike this was a doublerefractory ore combining sulphideoccluded gold with pregrobbing carbonaceous material that rendered the ore unsuitable for conventional cyanide leaching and carbon adsorption In most cases gold processing with cyanide leaching usually with carbon adsorption is still the core technology and the
Recovery of gold in sulfide ores has fallen into several categories First is froth flotation and second is cyanidation of the ores Using cyanide to recover gold from sulfide ores generally results in 30 to 35 recovery and the best I have heard of is around 50 recovery The fine coating of a iron compound definitely appears to be a key
Generally recovery of the gold from the sulfide concentrates requires further processing usually by roasting or wet pressure oxidation These pyrometallurgical or hydrometallurgical treatments are themselves usually followed by cyanidation and carbon adsorption techniques for
