  • Acid Leaching Copper Ore Treatment Method

    2020-06-04· The flowsheet discussed in this study is for treatment of 100 tons per day oxide-sulfide copper ore by the leaching process using sulfuric acid-ferric sulfate solvent. This flowsheet would also be suitable for a larger tonnage by proper sizing of the various units of equipment.

  • Sulphuric acid leaching of zinc and copper from Nigerian Complex

    2009-08-26· Dissolution results showed that the leaching rate of copper was lower than that of zinc. The highest recoveries of zinc and copper were obtained at a leaching time of 180 minutes, stirring speed of 160 rpm, particle size of 75 µm and a concentration of 1M H2SO4/1M H2O2. It was observed that the leaching rate of zinc and copper


    Mexican copper ore is a mixed ore containing mainly copper oxide and some copper sulfide that responds well to flotation. The joint techniques of flotation and leaching were studied. The results

  • Heap leaching Wikipedia

    Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from oreusing a series of stone reactions that absorb specific minerals and re-separate them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the ore, whereas in situ mining lacks these liners and pulls pregnant solution up to obtain the minerals. Heap leaching is widely used i

  • (PDF) Leaching of copper oxide with different acid solutions

    Leaching and adsorption of the copper ore sample was carried out using sulphuric acid of varying molarity -3M, 2M, 1.5M, 1M and 0.5M and two Lanthanum and Cerium nanoparticles adsorbents were

  • Copper Mining and Processing: Processing of Copper Ores

    Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different

  • Open Access The Leaching of Dolomitic-Copper Ore Using

    2017-05-07· The Leaching of Dolomitic-Copper Ore The Open Mineral Processing Journal, 2010, Volume 3 61 sessing the profitability of the process. The objectives of the study were to evaluate the leaching of low and high dolo-mitic-copper ore using H 2SO 4 as the leaching reagent. The

  • Leaching of sulfide copper ore in a NaCl–H2SO4–O2 media

    A study was made of the leaching of a sulfide copper ore in a NaCl–H 2 SO 4 –O 2 media after pre-treatment by agglomeration with H 2 SO 4(conc) and NaCl. The leaching variables evaluated included the amount of NaCl to be employed, the percentage of solids in the leaching solution, particle size of the raw mineral to be leached, and the preferable method of agitation in the leaching system.

  • Concentration of Ores Class 12 Leaching process

    2017-10-11· Normally, the ore is concentrated by separating it from the clay body in which it occurs either by gravity, sedimentation, or by a floatation process, before the extraction of the metal from the
