Froth Flotation Method JXSC Machine

· This froth flotation method is used to treat quartz sulfide ores or gold silver bearing pyrite and pyrrhotite containing gold telluride pyrrhotite chalcopyrite and other sulfide minerals The floatable gold telluride in the ores is first produced as a concentrate and then roasted and cyanided to expose gold and silver ores in sulfides and tellurides Because the middle and tailings after

Oxidative Hydrometallurgy of Sulphide Minerals

Sulphide minerals as pyrite FeS2 chalcopyrite and CuFeS2 are one of the most important sources of value metals such as gold silver coppe r zinc etc Due to the strong sulfur binding to these minerals metals are usually extracted by metallurgical process of chemical oxidation In Extractive Metallurgy process can be divided in Pyrometallurgy and Hydrometallurgy Particularly

Metallic sulphide and sodium carbonate interacting processes

At mix material roasting consisting of copper sulfide we used planning experiment methods There were found partial dependences between the effect of temperature and duration of the experience on the desulfurization degree They are presented in the form of straight line equations isochor for desulfurization extent from to % and at temperatures 500 600oC The air flow rate and the

In situ roasting and leaching of sulfide minerals

Roasting of sulfide mineral particles can be simultaneously accomplished using substantially identical procedures for the well 110 and the well 210 if desired Alternatively one of the wells can be used as an inlet well and the other well can be used as an outlet well For example the well 110 can be used as an inlet well wherein a mixture of fuel and an oxygen supplying gas is passed

OXIDATION OF SULFIDE MINERALS 4 PYRITE CHALCOPYRITE

roasting of ores the knowledge of the oxidation at relatively low tempera tures T < 100°C is scant and in general has been derived from studies on the weathering of sulfide minerals The major difficulty encountered in the study of the oxidation of sulfide minerals at T < 100°C is the identification and/or determination of the small amounts of products which are formed during

Gold Ore Roasting Techniques Mineral

· The roasting of straight pyritic ores involves the conversion of the iron sulphides to the oxide under oxidizing conditions with the evolution of sulphur dioxide and to some extent by catalytic action sulphur trioxide gas also In this chemical change the iron mineral is rendered more or less porous thereby permitting the dissolution of the contained gold by subsequent cyanidation
