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.
Copper Ore Processing Methods
Copper Ore Processing Methods. The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining.

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.
Copper Refining: From Ore to Market | INN
The copper is concentrated further by slurrying the ground ore with water and stone reagents. In this process, air is blown through the mixture, and the copper floats to the top.

How copper is made - material, used, processing, steps ...
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.
From Ore to Finished Product - Copper
Processing of Copper Ore The first step in processing the ore removed from the mine is to break the large rocks of ore into smaller pieces. This is accomplished by a variety of subsequent processing steps.

Copper-Arsenic Processing - Teck
Global production of copper concentrates is expected to increase by 3% year-on-year from 2015 - 2024. Arsenic is the main impurity present in copper concentrates, and is predicted to be above penalty limits in 10% of all copper concentrates produced in 2015.
12.3 Primary Copper Smelting
Copper is produced in the U. S. primarily by pyrometallurgical smelting methods. Pyrometallurgical techniques use heat to separate copper from copper sulfide ore concentrates. Process steps include mining, concentration, roasting, smelting, converting, and finally fire and electrolytic refining. 12.3.2 Process Description2-4
