    Effect of grinding media on zinc depression in a lead

    Effect of grinding media on zinc depression in a lead cleaner circuit. that iron hydroxide surface coatings generated by grinding media corrosion reactions are an effective depressant for sphalerite in this ore body even though it is known that an excess of these coatings could depress both galena and sphalerite flotation. These tests

    Study on the Interaction between Galena and Sphalerite

     · The results show that after mixed grinding of the galena and sphalerite the Pb content on the sphalerite surface increased with the decrease of Zn and Fe contents on the sphalerite surface. The lead ions from galena were obviously absorbed onto the sphalerite surface while the zinc and iron ions from sphalerite were not obviously migrated to

     · Chapter 7. Depression of sphalerite with cyanide and zinc sulphate 104 Deactivation with zinc sulphate At Rosh Pinah Mine the selective flotation of the leadzinc sulphide composite is carried out at mildly alkaline pH values. However depending on the flotation conditions sphalerite can be activated by products from the dissolution and/or

    GalenaSphalerite Flotation Separation Method

     · The problem of treating oxidized leadzinc ores for the production of highgrade lead zinc flotation concentrates is a complex problem due to the nature of the ores and to the soft sliming characteristics of the lead and zinc minerals. The ore for treatment is a leadzinc carbonate ore in a mixed siliceouslime carbonate gangue. The association of the minerals and gangue requires a 65 mesh

    Recent Studies on the Application of Eriez Flotation

     · Highly Liberated Zinc Ore A high grade sphalerite (ZnS) ore sample was obtained from a zinc mining company in the USA. The ore contains about 12 sphalerite ( Zn). Quantitative XRD analysis indicated that the major gangue mineral is dolomite (71 ) with 10 of quartz and minor traces of albite calcite chalcopyrite galena and pyrite.

    GrindingMineral Processing

    Grinding equipment for mineral processing. The final fineness of the product mainly depends on the number of times the ore particles pass through the grinder. The longer the grinding the smaller the particle size. Separate crushing and grinding steps are necessary the ball mill can only receive the broken ore particle and then grind to the
