Copper processing, the extraction of copper from its ores and the preparation of copper metal or chemical compounds for use in various products. In its pure form or as an alloy, copper (Cu) is one of the most important metals in society.
Extraction and refining. The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used. The major differences in equipment are the use of highertemperature refractories and the increased cooling required to accommodate the higher operating temperatures in nickel production.

processing and Technology research center from the University of Johannesburg, to study at room temperature, the extraction of copper content by making use of ammonia and nitric acid solution. Both ammonia and nitric acid were prepared at desired concentration. Feed: Copper cobalt oxide ore from Katanga(southern DRC)
Oxide–sulfide 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 presented 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.
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.

This class of manganese ore containing copper, nickel, cobalt and manganese is abundant over vast area of deep
in a flotation separation process wherein oxide copper ores in subdivided form are concentration by slurrying said ores in an aqueous solution of a floation reagent followed by generating gas bubbles in the slurry to float the oxide copper and recovering the concentration oxide copper from the surface of the slurry, the improvement therein ...
Heap leaching is an industrial mining process to extract precious metals, copper, uranium, and other compounds from ore via a series of chemical reactions that absorb specific minerals and then reseparates them after their division from other earth materials.
The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different chemistries of the ore. Copper oxides are more abundant near the surface, but are considered lowgrade ore, with a lower concentration of copper.
Copper production About 80 % of ... collectors, and dolomitic copper oxide ores are sulfidized with sodium hydrogensulfide and then floated . Pyrometallurgical copper production ... Low volume of offgas and correspondingly high concentration of SO2 and low quantity of flue dust, if oxygen is used
Introduction to Mineral Processing. ... The combined rougherscavenger concentrate may be 5% Cu and % Mo (a concentration factor of 3 to 10 times is typical). ... The figure below is a simplified schematic of a typical copper solvent extraction process. Oxide copper ore, lowgrade copper sulfide overburden, and other coppercontaining ...
Lead and Zinc Ore Concentration If the mineral veins separate from the rock cleanly, then processing workers can concentrate the ore by taking advantage of the greater weight mineral compared to the rock. Jigging separates coarse lumps. In this process, the crushed ore is agitated or shaken in water with a vertical motion.
