Copper extraction
Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper ores consists of a series of physical, chemical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors. Oxide ores are generally processed using hydrometallurgy. This process uses aqueous (water-based) solutions to Copper Mining and Processing: Processing Copper Ores

Concentration of Ore: Definition, Classification, Methods EMBIBE
Ores found on the earth contains many impurities like sand, rocks, and grit in them, which are collectively known as “Gangue”.The concentration of ore is a method of removing gangue particles or other impurities in order to purify the ore. This process is also called Ore-dressing and benefaction.It is a very crucial step to obtain a pure metal from Concentration, dressing, or beneficiation of ores is the process of removing undesirable particles from ore. There are various steps to it. The variations in physical characteristics of the existing metal complex and that of the gangue are used to separate the needed material from the ore. Gangue is a mineral that contains undesirable elements.Different methods of concentration of ores Unacademy

The Extraction of Copper Chemistry LibreTexts
This is used to make sulfuric acid via the Contact Process. An overall equation for this series of steps is: 2CuFeS2 + 2SiO2 + 4O2 → Cu2S + 2FeSiO3 + 3SO2 (1) (1) 2 C u F e S 2 + 2 S i O 2 + 4 O 2 → C u 2 S + 2 F e S i O 3 + 3 S O 2. The copper (I) sulfide produced is converted to copper with a final blast of air.Subject to the characteristics of the ore and the scale of the process, pre-concentration can be proficient using several methods alternating from simple techniques, such as hand sorting andPre-concentration of copper ores by high voltage pulses.

Pre-concentration of copper ores by high voltage pulses. Part 2
The JKMRC has recently reported a novel ore pre-concentration method using high voltage electrical pulses (Part 1 of this paper). The technique utilises metalliferous grain-induced selective breakage under a controlled pulse energy input, and size-based screening to separate the feed ore into body breakage and surface breakage Concentration Cu = (5/124) x (1000/100) = 0.4 M. The two concentrations should be the same. However, this calculation works only approximately because ‘basic’ copper carbonate also contains an equimolar amount of Colourimetric determination of copper ore

Extraction of Copper: Detailed Process The Chemistry
Modern smelters are designed to collect at least 90 percent of the sulfur in the feedstock. These steps result in the following reaction: 2 CuFeS2 + 2 SiO2 + 4O2 → Cu2S + 2 FeSiO3 + 3SO2. Copper Concentration of ores is done before using all of these methods of metal extraction based on their reactivity. Many impurities, such as rock fragments, sand, and other impurities, can be present in the ore. Matrix or gauge refers to the impurities in a mineral. Concentration ore refers to the process of removing matrix or gauge from an ore.Concentration of Ores GeeksforGeeks

2. Froth floatation method is used for concentration of the ores of the metals whose ores are in sulphide form. The concentration of sulphide ores of copper, lead and zinc metal are carried out by this method. In this method, the fine powder of the ore, and water are filled in a big vessel. Substances like pine or turpentine oil are added to it. 3.However, copper oxide ores tend to have the characteristics of strong surface hydrophilicity, high combination rate, fine particle size, serious mud problems, and complex mineral composition [8], [9]. Therefore, it is difficult to recover copper oxide resources efficiently by conventional copper sulfide ore separation method.Flotation of copper oxide minerals: A review ScienceDirect
