Table of ContentsChemistry of Sodium SulfideSulfidization Sodium Sulfide in Sulfide Minerals Flotation Sodium sulfide is one of the most widely used alkali metal sulfides in the flotation of copper lead and zinc minerals in their oxidized form The sulfidization process developed in the USA in 191520 for oxide copper minerals flotation is especially suitable for oxidized lead ores in

Jul 09 2019 · Copper Sulfide Ore and Flotation Process July 9 2019 July 9 2019 by JXSC Mining 1 Types of copper sulfide ore 1 Single copper mineral Its ore characteristic is relatively simple and the only useful component that can be recycled is copper The gangue minerals are

In coppergold flotation plants pyrite which is depressed in copper flotation is often floated subsequently with the addition of sodium sulfide Na 2 S to recover the associated gold For the first time this study investigated the role of Na 2 S responsible for the flotation of pyrite depressed in chalcopyrite flotation through flotation tests and CyroXPS Xray photoelectron spectroscopy

In parallel the secondary ions present in seawater cause a colloidal precipitation and a strong buffering effect which difficult the operation at high alkaline condition The objective of this review is to present a summary of the current knowledge on the subject of seawater flotation processes highlighting the copper sulphide ores flotation

The research results provide a theoretical basis for promoting sulfide flotation of zincoxide ore and has extensive practical application value 2 Experimental 21 Materials and reagents The smithsonite was from Yunnan China and the ore particle size was 38–74 μm

In the flotation of copper–zinc massive sulfide ores the flotation properties of copper and zinc are determined by the nature and composition of the ore Selectivity between chalcopyrite and sphalerite in principle is determined by the type of copper minerals present in the ore

If copper is to be made from an ore having a total content of 15 per cent it must be concentrated or removed from the ore by some hydrometallurgical method Flotation is generally successful for the sulfide minerals and flotation after filming with sulfide seems to work in many cases on the pure carbonate minerals

Flotation of Sulphide Ores Sulphide ores are the major sources of base metals like Copper Lead Zinc Nickel and Cobalt Beneficiation of

What is a Flotation Collector For industrial sulfide mineral flotation the xanthates and dithiophosphates are the major classes of Flotation Collectors compounds used where M is either Na or K and R is a relatively short hydrocarbon chain typically containing two to five carbon atoms The solubility pH application range physical state

Flotation tests were carried out in a D12Denver flotation laboratory cell in the presence and absence of chitosan andor sodium cyanide depressant which is commercially used as pyrite depressant in sulfide mineral flotation process

The trends are similar with the results obtained for flotation of galena The initial feed carried 29 gpt silver on an average Blank tests no GrC depressants showed that approximately 150–200 gpt silver content in the sulfide mineral concentrates

Tecflote is a new group of nitrilebased collectors for sulphide flotation The fact that it is insoluble in water results in some interesting implications for its actual working mechanism

In ore beneficiation flotation is a process in which valuable minerals are separated from worthless material or other valuable minerals by inducing them to gather in and on the surface of a froth layer Sulfide and nonsulfide minerals as well as native metals are recovered by froth flotation

The froth flotation method is widely used to treat various veins of gold and silver ores for the following reasons 1 In most cases the froth flotation process can enrich gold and silver in sulfide concentrate to the greatest extent and discard a large number of tailings thus reducing the smelting cost

Flotation tests were carried out in a D12Denver flotation laboratory cell in the presence and absence of chitosan andor sodium cyanide depressant which is commercially used as pyrite depressant in sulfide mineral flotation process

The use of sodium sulfite in the flotation of sulfide ores using a dialkylthionocarbamate as collector enables us to obtain in most cases a good selectivity for copper sulfide from other

sulphide ore flotation practices in brief and processes adopted in HZLs 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

Flotation of sulfide copper ores Sulfide copper ores are considered easy to treat provided that the main copper mineral is chalcopyrite In case the ore contains secondary copper minerals such as chalcocite bornite and covellite depression of pyrite may be a problem because the pyrite can be activated by copper ions generated during the

The flotation of sulphide minerals and their modulation has been a subject of investigation for many years The influence of pH D p D b and xanthate concentration on the sulfide minerals

area of air that is rising through the flotation cell by reducing the bubble diameter ie micro or picobubbles or by increasing the gas rate Even with the generation of smaller bubbles recovery can still be challenging FIGURE 1 Conventional flotation data for industrial sulfide flotation

The flotation of sulphide minerals from siliceous and calcareous gangue ainerals always g1Yes a that is eontaminated to a greater or lesser degree with the gangue minerals eTen though the collectors used do not show any appreciable colleeting properties for the gangue minerals when they are tre·ated alone In an
