which process is involved in the extraction of pure copper from sulphide ore

  • Hydrometallurgical Copper Extraction Process

    This invention relates to a process for the extraction of copper from copper ore or concentrates, in particular sulphide ores, in which the concentrate is subjected to acid leaching to extract the copper therefrom.

  • THE EXTRACTION OF METALS AN INTRODUCTION

    For example, pure aluminium oxide is obtained from bauxite by a process involving a reaction with sodium hydroxide solution. This is described in detail on the aluminium page in this section. Some copper ores can be converted into copper(II) sulphate solution by leaving the crushed ore in contact with dilute sulphuric acid for a long time.

  • 50.5 EXTRACTION OF METALS- METALLURGY

    The process of extracting pure metal from its ore is known as metallurgy. . Since, the nature of the ore and also the properties of different metals are different, therefore, it is not possible to have the universal scheme which may be applicable to all the metals.

  • Extraction of Aluminum, Copper, Zinc & Iron Study.com

    Extraction of Copper. Chalcopyrite(CuFeS 2) is the commonest copper ore. Copper is mainly extracted from the sulphide ore(Cu 2 S) by the self reduction process. The ores are often low grade (0.5% Cu) and require concentration (up to 15-20% Cu). The process contains the following steps. 1.

  • Copper Extraction from Sulfide Ores Latest Contents

    This process is used for the extraction of copper from low grade sulfide ore. In this process, the crushed and ground ore in bulk (about 100,000 tons) is exposed to air and water in big tanks. The air in the presence of water gradually oxidizes copper and iron sulphides to their surphides.

  • Extraction of Copper metalbureau.com

    The process of extraction of copper depends upon the nature of the ore available. The important minerals used for extraction of copper are chalcopyrite and chalcocite. The extraction of copper is mainly through the chemical reduction and the smelting process. In the first stage, the ore is crushed and concentrated by froth floatation process.
