copper ore concentration processing

Copper processing Copper processing Roasting smelting and converting Once a concentrate has been produced containing copper and other metals of value such as gold and silver the next step is to remove impurity elements In older processes the concentrate containing between 5 and 10 percent water is first roasted in a cylindrical refractorylined furnace of either the hearth or

The percentage of copper in the actual ore is too low for direct extraction of copper to be viable The concentration of ore is required and it is done by the Froth Flotation method Concentration of Ore The ore is crushed into a fine powder and a suspension is created in water To this are added Collectors and Froth Stabilizers

The process of extracting copper from copper ore varies according to the type of ore and the desired purity of the final product Each process consists of several steps in which unwanted materials are physically or chemically removed and the concentration of copper is progressively increased

Copper ore divides into ore sulfide ore oxide and mixing ore according to its oxide rate The main process for copper ore is flotation for refractory mixed copper ore and refractory oxide ore normally use hydrometallurgy process It is a high technological enterprise that integrated research manufacture sales and service The company has multiple subsidiaries such as Mineral

When an ore has a low percentage of the desired metal a method of physical concentration must be used before the extraction process begins In one such method the ore is crushed and placed in a machine where by shaking the heavier particles containing the metal are separated from the lighter rock particles by gravity

Another method of concentration of ores is the Froth Flotation Method This is the process for concentration of primarily sulphide ores It has the advantage over gravity separation because it can collect even the extremely fine particles of minerals The process uses the difference in the wetting characteristics of minerals and gangue

Copper can be extracted from nonsulfide ores by a different process involving three separate stages Reaction of the ore over quite a long time and on a huge scale with a dilute acid such as dilute sulfuric acid to produce a very dilute copperII sulfate solution Concentration of the copperII sulfate solution by solvent extraction

When reviewing Methods of Eliminating Copper from Gold Ores we see that several methods have been suggested to eliminate copper from ores prior to cyanidation Preliminary extraction of the copper with sulphuric or sulphurous acids may be applicable to ores containing oxidized copper minerals such as malachite azurite and chrysocolla but these acids have but little effect on sulphide copper

An acidic solution is then added to increase the concentration of copper and allow the liquid to conduct electricity The liquid is then moved to tanks containing thin sheets of either copper “starter sheets” or stainless steel “blanks” Similar to the sulphide ore refining process an electrical

The concentration of these minerals in an ore body is low Typical copper ores contain from 05 Cu to 1 or 2 Cu Pure copper metal is mostly produced from these ores by concentration smelting and refining About 80 of the worlds copperfromore is produced by concentrationsmelting refining of sulfide ores

Copper Processing Plant description There are mainly three types of copper ore sulfide type copper ore oxide type copper ore and mixed ore Based on abundant experiences on copper mining project Prominer supplies customized solution for different types of copper ore General processing technologies for copper ore are summarized as below

Ore microscopy characterization as a mineral processing control Mar 20 2018 The Bor Copper Mine has expanded mine workings to the Cerovo field margins where the same type of porphyry copper ore was found for which the Bor results of copper ore concentration at the Bor Cerovo flotation plant and 15 million members 100 million publications 700k research projects

Processes copper mining and production Copper is found in natural ore deposits around the world This page explains copper mining the production route taken from orecontaining rock to a final product that is the highestpurity commercial metal in existence and used in a wide variety of applications essential to modern living

Copper Ore Processing MethodsThe four major steps in the production of marketable copper are mining concentrating smelting and refining In a few instan

Process steps include mining concentration roasting smelting converting and finally fire and electrolytic refining 1232 Process Description24 Mining produces ores with less than 1 percent copper Concentration is accomplished at the mine sites by crushing grinding and flotation purification resulting in ore with 15 to 35 percent copper

The concentration of these minerals in an ore body is low Typical copper ores contain from 05 Cu to 1 or 2 Cu Pure copper metal is mostly produced from these ores by concentration smelting and refining About 80 of the worlds copperfromore is produced by concentrationsmelting refining of sulfide ores

As expected the copper in the circuit reduced to a low level but when sulfide copper–gold ore processing resumed the copper concentration in the leach circuit did not attain previous levels even though a higher copper orebody was being mined The copper recovery plant was operated intermittently for a few months and was eventually shut down

Unlike the other processing routes shown in Fig 5 the direct ore smelting route is not used commercially for the production of copper or nickel metal although ferronickel is produced by smelting nickel laterite ores without any prior concentration These various processing routes are discussed in more detail later

If sulfide ores containing iron and copper are to be smelted an understanding of both the iron and the copper systems is needed Again as in Figure 213 for the Cu–S–O system the calculations are limited to oxidation by industrial oxygen so that the pressure of SO 2 will be about 1 atm except where oxygen pressure is appreciable near
