  • An Investigation Of Copper Recovery From A

    Current copper deposits contain significant amounts of secondary non-sulphide minerals and newly discovered deposits are increasingly complex. As a result research into the improvement of sulphide-oxide copper ores processing through the use of mixed collector systems has surged.

  • An Investigation Of Copper Recovery From A

    Chapter 2 Literature Review. Current copper deposits contain significant amounts of secondary non-sulphide minerals in the form of oxide ore. Secondary minerals such as malachite Cu2OH2CO3and chrysocolla CuAl2H2Si2O5OH4 nH2O contain economic quantities of copper

  • Sulfide Vs Oxide Ore

    differences in processing sulfide and oxide gold ores. There are two distinct types of copper ore the sulfide ore and the oxide ore. The sulfide ores are beneficiated in flotation cells while the oxide ores are generally leached.

  • Acid Leaching Of Oxidesulfide Copper Ore Prior The

    Oxidesulfide copper ore was sampled from the ore body Cerovo C1 south deposit and used in this study. The chemical composition of the ore sample is pre-sented in Table 1. From Table 1 it can be seen that the high copper concentration is in the sample as well as the high copper oxide content while the sulfide copper concentration is lower.

  • 12 Supergene Ore And Gangue Characteristics

    In VMS deposits copper and other metals are mobilized from primary massive sulfide ore and reprecipitated at depth. This precipitation of Cu sulfides with high CuS ratios can produce an economically significant copper enrichment at the reactive redox boundary between massive sulfide protore and downward penetrating fluids.

  • 24 Iron Oxide Coppergold Mineral System Geoscience

    Iron oxide copper-gold IOCG deposits Hitzman et al. 1992 are a diverse family of mineral deposits characterised by the following features 1 Cu with or without Au as economic metals 2 hydrothermal ore styles and strong structural controls 3 abundant magnetite andor hematite 4 Fe oxides with FeTi greater than those in most igneous rocks and 5 no clear spatial associations .

  • Copper Mining And Extraction Sulfide Ores

    The smelter for sulfide ores produces sulfur dioxide gas. This is scrubbed from the flue gases to make sulfuric acid for leaching copper from oxide ores. Scrubbing sulfur dioxide also protects the environment. For example FeOs SiO 2 s FeO.SiO 2 slag This is very similar to the removal of impurities in the blast furnace.

  • Atacamite In The Oxide Zone Of Copper Deposits In Northern

    Nov 28 2006 Copper minerals are atacamite and brochantite within the oxide zone and chalcocite covellite and pyrite in the enriched zone. Primary sulfides comprise chalcopyrite bornite molybdenite tennantite and pyrite. Reserves recoverable by open-pit mining are 79 Mt of oxide ore at 1.18 Cu and 231 Mt of sulfide ore at 1.13 Cu.

  • Flotation Of Mixed Copper Oxide And Sulphide Minerals With

    Mar 01 2009 The ore mined is from a primary copper sulphide deposit with separate additional deposits of copper oxides. In conjunction with Ausmelt Chemicals Minto is currently investigating options to recover copper oxide and sulphide minerals using flotation by blending their primary sulphide ore with oxide ores.

  • Leaching Of Lowgrade Copper Ores A Case

    copper within the RTB Bor include oxide and mixed oxide-sulphide ores at the copper deposit Kraku Bugaresku -Cementacija . This deposit in the calculation of reserves in the contour of boundary contents of 0.2 Cu is consisted of four ore bodies C1 C2 C3 and C4 which are similar in generic

  • Flotation Of Mixed Copper Oxide And Sulphide Minerals

    At a blend of 70 sulphide ore and 30 oxide ore the rougher scavenger copper recovery was as high as 95.5. The copper recovery from the blended ore using a mixture of collectors was shown

  • A Fresh Approach To Sulfide Ores Cim

    Jun 26 2017 T he copper mining industry is reaching a turning point. Surface oxide deposits are depleting and copper miners are turning their attention to untapped sulfide ores found deeper underground. However sulfides require more expensive processing techniques since they are not responsive to standard technologies that are used in oxide heap leaching.
