difference of oxide and sulphide flotation

The milled ore/gangue powder is mixed with a liquid and aerated in the flotation step The less dense ore rises in the froth to be collected while the gangue sinks to be discarded Flotation separates the metallic minerals from the gangue this way and – in the case of copper/ molybdenum ores – separates molybdenite from copper sulphide AN INVESTIGATION OF COPPER RECOVERY FROM A SULPHIDE OXIDE ORE WITH A MIXED COLLECTOR SYSTEM by Cytec Promoter 6494 hydroxamate and DETA The copper recovery malachite recovery minor copper recovery and copper grade responses were optimized using JMP The relationship between the flotation recovery o See More Detail

copper mining sulphide to oxide - bosenmeerzicht Cobalt Copper Sulfide Mine mixmasala Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99 99% pure copper called cathodes which will ultimately be made into products for everyday use The most common types of ore copper oxide and copper sulfide undergo two different

Other turnkey modular systems for pre-concentrating coarse sulphide-gold ores include the Python plant and the Gravity Flotation Intensive Leach (GFIL) systems both of which incorporate the InLine Pressure Jig Regrinding of pre-concentrated non-refractory sulphide complex gold material by a conventional regrind mill can produce free gold

Traditional sulphidisation flotation techniques which are widely used on copper oxide ore can not be used in sulphide/oxide blends for simultaneous sulphide and oxide copper flotation as the sulphidising reagent will suppress the flotation of sulphide minerals as shown within this case study

Some of the most important copper oxide minerals are listed in Table 19 1 In most cases oxide copper ores contain more than one copper oxide mineral and also contain mixtures of sulphide and oxide copper minerals From a processing point of view the oxide copper ores can be divided into the following five groups Oxide copper ores

Nickel processing preparation of the metal for use in various products Although it is best known for its use in coinage nickel (Ni) has become much more important for its many industrial applications which owe their importance to a unique combination of properties Nickel has a relatively high

semiconducting sulphide and compound oxide electrodes are today under intense What is the difference between the anodic semireaction paths on semi-conducting sulfides in the redox process Flotation selectivity between pyrite and non-ferrous sulphides

sulphide ore flotation practices in brief and processes adopted in HZL's plants It also highlights RD efforts made and new technologies adopted in one of the most complex sulphide ore beneficiation plants to solve metallurgical problems in flotation process Key Words Froth flotation Sulphide flotation Control system Flotation

Iron hydroxide coatings hamper gold flotation but are hardly the main cause for free gold rejection At Batu Hijau manganese hydroxides were strongly enriched on the rejected free gold particles In most flotation plants sulfur and silver on gold grains (in all likelihood in the form of silver sulfide) promoted gold flotation

Nickel Oxide vs Nickel Sulphide

Mar 31 2007Re Nickel Oxide Vs Nickel Sulphide Nickel sulphides are where the majority of the world's nickel has come from until now The technology is well-understood and tried and tested The sulphide ore is crushed and flotation cells are used to form a nickel sulphide concentrate The concentrate is then roasted in a smelter to produce nickel metal

Sulphide Gold Ore Treatment by Leaching and Flotation Process Problem with gold recovery from sulphide ore How may a mill get the maximum recovery of gold from a sulphide ore at the least capital cost and at the same time obtain the highest net return More Info Copper Ore Types Sulfides vs Oxides Investing News Network See Details

Although the flotation of sulphide ores has been practised and studied for almost 75 years the mechanisms that govem the interfacial processes that are involved in flotation and flocculation are poorly understood mainly because of the difficulties of identifying and controlling the surface species as well as the solution species

The useful minerals of Jinchuan high-grade copper and nickel suphfide ores were mainly nickel and copper whose grade were respectively 1 42% and 1 01% The content of MgO and SiO2 main gangue components reached 57 89% The key to improve the separation indexes of flotation concentrate was to inhibit the gangue minerals effectively therefore the effects of different kinds of regulators on

Copper oxide ores have occasionally been treated via froth flotation via sulfidation of the oxide minerals with certain chemicals which react with the oxide mineral particles to produce a thin rime of sulfide (usually chalcocite) which can then be activated by the froth flotation plant Sulfide smelting

sulphidization for flotation of oxidized sulphides has also been demonstrated (Newell et al 2006) When introduced in the slurry the sulphidizer dissociates into the species H 2S H S- or S 2- depending on the pH These ions react with the copper oxide minerals to form a sulphide layer on the surface of the oxide minerals (Zhou and Chander
