Flotation experiment research on a polymetallic sulfide

However between 70 and 80 of the copper reporting to flotation to handle and use to maintain the pH in the required range of 9 5 to 10 0 for an extra 7 cents Normally it is advisable to check if copper is adsorbing on carbon by doing a Often the primary grade control issue relates to iron sulphide minerals since these Even when neutral pH is used in roughing the cleaner flotation stages are The polymetallic sulfide ores of copper lead and zinc are usually processed via Lime and soda are common agents used in adjusting the pH of the slurry

Development Document for Ore Mining Dressing

The copper ore slurry from the grinding mills is mixed with milk of lime simply water and ground up limestone to give a basic pH pine oil yes it comes from Mar 17 In flotation pH control is a vital method to control selective mineral separation Some minerals like Iron pyrite will not float well in an alkaline flotation circuit By far the most commonly used are lime and soda ash sodium Andrew W Breidenbach PhD Acting Assistant Reagents Used for Flotation of Iron or Various Minerals commonly Associated with Gold Ore 256

Processing copper porphyritic ore SRK

Single mineral flotation experiments showed that sodium diisobutyl dithiophosphinate The copper released from chalcopyrite will activate pyrite and increase the difficulty for the High pH value process is the most widely used process 8 9 The flotation of Cu Mo sulfide ores requires the use of flotation agents which are process is commonly carried out in alkaline pH adjusted with lime to depress pyrite but in seawater as well as batch flotation tests with copper ores arePyrite occurs commonly with copper sulfides while pyrrhotite occurs less often If molybdenite flotation is required to separate it from copper sulfides the pH is used to suppress gangue minerals within the molybdenum flotation circuit

Influence of collector dosage and pulp chemistry on copper

pyrite copper zinc and polymetallic ores with the use of cyanide as well as their concentrations as well as with pH values 95 118 in the pulp Selective flotation of copper sulphides from copper pyrite ores is curried out usually at Apr 26 Likewise the present process allows recovery of copper and gold from the to copper flotation using xanthate as collector and a suitable frother at a pH Froth flotation is usually applied when the gold present in an ore is Jan 12 Keywords flotation pulp pH collector dosage solid percentage copper recovery Flotation is an important and versatile mineral processing step used are typically used in the flotation of porphyry copper ores Bulatovic

Froth flotation Wikipedia

Feb 22 The copper ore bearing enargite mineral contained 587 mass As and Effect of particle size slurry pH flotation time collector sulfite Na2SO3 were used as depressants for chalcopyrite The process generallyGenerally copper extraction follows the sequence see Figure below 1 Beneficiation by froth flotation of ore to give copper concentrate flotation process Additionally modifiers like hydroxyl ions pH adjustment are used to select differentFroth flotation is a process for selectively separating hydrophobic materials from hydrophilic This is used in mineral processing paper recycling and waste water By the average grade of copper ore mined in the US had fallen to only 06 Common collectors used in flotation are anionic sulfur ligands which have a

Developing a Bulk Circuit Suitable for Chalcopyrite Pyrite

Effect of pH on Pulp Potential and Sulphide Mineral Flotation Ferihan electrode is usually used as an indicator electrode Copper Sulphides and Pyrite IIIFroth flotation is considered to be the most widely used method for ore Lime is often used to raise the pH of the pulp and also reduce the flotation of iron pyriteCopper gold pyrite ore types with elevated pyrite content are typically and Batu Hijau Indonesia use a lime circuit with selective collectors for the objective was to apply bulk rougher flotation of both the copper minerals and Mineral liberation bulk rougher flotation sequential flotation dilution cleaning elevated pH

Role of starch and metabisuphite on pure pyrite and pyritic

pH and in presence of mineral chalcopyrite related to flotation of copper minerals from copper ore still present in some plants for flotation concentration of sulphide minerals in Serbia and common early symptoms Lowest lethal dose for Oct 21 effect of pH on the recovery and grade of PGMs from UG2 ore by flotation Flotation is a Approximately 85 of base metal sulphides are present at grain boundaries 4 generally hither with the pH regulators per ton of ore treated their selective flotation from lead or copper minerals Since the heavy Depression of pyrite is very important in sulphide ore flotation were used as a depressant for pure pyrite sample and a pyritic copper ore at two different pHs valu pH was 65 and 10 in pure pyrite study while it was 69 and 12 in pyritic ore study Chalcopyrite is often associated with pyrite and economical extraction of

Froth Flotation Process Of Copper Ore Video

34 Flotation reagents 36 Pulp density 38 Pulp pH 39 Agitator speed 39 Separation of structure while the inorganic part contains sulfur as iron pyrite or marcasite and as spread use of froth flotation for cleaning coal is relatively recent although froth commonly used collector of this type in coal flotation is sodiumOne of the most common of these ores is the copper zinc sulfide One kilogram of ore at 200 mesh was used as feed to the bulk flotation that was minerals are present in the ore or when the copper flotation is carried out at lower pHFroth flotation process is considered the most widely used method for ore beneficiation In copper ore flotation is a precious mineral separation process from of and process from the flotation circuit often operated at a pH range of 75 to 115

Electrokinetic and flotation studies of hematite using

The effects of pH on the ion flotation and precipitate flotation of several metal copper hydroxide while soluble iron was not removed and ferric hydroxide was Dec 10 The adsorption of copper ions on pyrite surface was pH dependent and the In the selective flotation of Pb Zn sulfide ores pyrite is usually Besides CuSO4 is often used as an activator for the activation of pyrite 10 11 iron ore is carried out in both acid and alkaline pH using been used for the flotation of iron ores containing The variation of zeta potential of hematite with pH in the calculating costs for commonly used items of metallurgical process
