Environmental contamination from mines producing acid rock drainage which is caused by sulphide mineral oxidation represents one of the most significant environmental problems facing the
Using the density difference between gangue and nickel sulfide ore the ore slurry enters the heavy medium cyclone under the pressure of for separation The underflow part is nickel sulfide mine while the overflow part is silicate gangue mine The main application equipment dense medium hydrocyclone
Variations in the recovery of platinum group metals PGMs are often attributed to mineralogical and other natural ore type variations To increase the recovery of PGMs by the flotation process a comprehensive understanding of gangue and valuable minerals is essential for optimising the extraction and processing of metals Recoveries may be improved if the
In anticipation of future demands a comprehensive understanding of the chemical and mineralogical characteristics of nickel bearing minerals is a prerequisite to devising effective nickel

Phoenix Tailings CO2 GONE process uses and recycles CO2 to extract energy relevant minerals primarily nickel Ni and magnesium Mg from iron and aluminum rich ore through carbonation with CO2 Using CO2 with high pressures temperatures and mixing breaks down the rock structure and enables greater extraction of energy relevant elements like Ni and
Carboxymethyl cellulose CMC is widely used in mineral processing as a flotation depressant mainly for the depression of carbonate and talcaceous gangue in the flotation of Cu Ni sulfide and PGM
Behind all successful mining operations is a deep understanding of a deposit s mineralogy — not only the valuable minerals but also the valueless or gangue minerals One of the main reasons that new mining projects fail is geometallurgical problems and therefore ongoing mineral characterisation is critical during life of mine writes IAIN COPP
Serpentine and olivine are the main nickel minerals with an average nickel concentration of wt% and wt% respectively Gangue Min erals of Serpentin e is the main nickel

Carboxymethyl cellulose CMC is widely used in mineral processing as a flotation depressant mainly for the depression of carbonate and talcaceous gangue in the flotation of Cu Ni sulfide and PGM
Pyrite is the most abundant sulphide gangue mineral in all cobalt ores and it may contain significant amounts of cobalt in the form of cobaltiferous pyrite De Cuyper 1981 When present as a gangue mineral it is problematic in terms of its impact on selective flotation of cobalt minerals Barbery 1986 Pyrite is readily oxidised under
Nickel laterites on the other hand are found nearer or at the surface and are generally classified as limonitic the upper layer based on nickeliferous limonite; Fe Ni O OH or saprolitic the
Nickel in olivineOlivine which is an important mineral of many nickel sulfide mines and suitable for permanent CO2 sequestrationCO2 sequestration is regarded as non recoverable and discarded in
In general gangue materials consist of quartz dolomite muscovite chlorites mica talc and clayey minerals Kanda 2013; Shengo 2013 Gangue material removal prior to the actual processes is of paramount importance as they are responsible for most of the reagents overconsumption Gangue materials also affect the operation of processes
The Empress Nickel Mine is located in Midlands Zimbabwe It was initially discovered in 1955 and has since operated as a significant mining site However at the time of data entry the mine was closed and there were no known plans to reopen it The ore extracted from the Empress Nickel Mine consists of pyrrhotite sphalerite and ilmenite
lation of minerals especially Rne sulRdes with coarse gangue minerals thus leading to nickel loss Flotation Practice in Nickel Sulde Deposits Nickel sulRde minerals such as pentlandite can in general be separated from their gangue by Sotation using a thiol group of collectors like xanthates and alkyl dithiophosphates in the presence of
