Current operation 2003 is to blend 80 porphyry with 20 skarn ores resulting in an acceptable concentrate grade and recovery However when the proportion of skarn ore in the plant feed exceeds 20 low flotation recovery is often observed Approximately 20 of the copper and 30 gold losses occur through the rougher flotation circuit

1 Froth Flotation Fundamental Principles

Problem A copper ore initially contains 209 Cu After carrying out a froth flotation separation the products are as shown in Table 1 Using this data calculate a Ratio of concentration b Metal Recovery c Metal Loss d Weight Recovery or Yield e Enrichment Ratio

Examples 15 show the effectiveness of depressant A in the separation of copper lead and zinc ores EXAMPLE 6 The flotation was a leadzinc ore containing galena and sphalerite together with pyrite and silicous gangue minerals After grinding the ore assaying about 12 lead and 55 zinc was treated using a Denver Laboratory Flotation cell

Atomic Force Microscope AFM then the depression of pyrite and pyrrhotite using the synthetic polymers developed by Cytec Industries The results show that for xanthategold system dixanthogen is the only species that renders the surface hydrophobic Chemisorbed xanthate is observed on the gold surface but is hydrophilic

Jul 01 2020 Copper and sulfur in copper ore have strong collection properties which is also conducive to improving the recovery of associated gold in copper sulphide ores The flotation effect of refractory coppersulfur ore containing secondary copper minerals is better than that with butyl xanthate but its selectivity is worse

Optimization and mechanism of goldbearing sulfide flotation

Jun 05 2014 In order to overcome the difficulty of extracting gold from goldbearing sulfide ore by cyanide process flotation was adopted based on mineralogical analysis Mineralogy shows that gold particles are of superfine structure and mainly enclosed by sulfide ores Primary goldbearing sulfide ore is finegrained pyrite and arsenopyrite The paper describes the effects of ratios and dosage of

to concentrate ores for economical smelting Flotation is a selective process and can be used to achieve separation from complex ores such as leadzinc copper zinc etc Initially developed to treat the sulphides of copper lead and zinc the field of flotation has now expanded to include oxides such as hematite and cassiterite

The clays in colloidal form are suspended inside the water and incorporates the ore of interest avoiding copper recovery during the flotation stage 9 This effect is reduced by adding saline solution and in this way reducing the swelling ability of the clay in the flotation pulp 10 13

Flotation Behavior of Complex Sulfide Ores in the Presence

Jun 12 2017 In this study chitosan polymer was tested as a potential selective green depressant of pyrite in the bulk flotation of galena PbS and chalcopyrite CuFeS 2 from sphalerite ZnS and pyrite FeS 2 using sodium isopropyl xanthate as a collector and 4methyl2pentanol MIBC as a frother Flotation tests were carried out in a D12Denver flotation laboratory cell in the presence and
