Optimizing the Rougher Flotation Process of Copper Ore
Correlation is used to find the process variables that affect the grade copper and recovery. Some of the factors that are studied as input variables are the copper grade of the ore at the entrance of the flotation process, the amount of reagents and foaming agent used, and the granulometry, among others.

Heap Leaching of Copper Ores – State of the Science
Heap leaching accounts for around 20% of the global production of copper. In heap leaching coarsely crushed ore particles are contacted with an aqueous lixiviant percolating through large packed beds (heaps) of the ore particles, with the loaded solution collected at the foot of the heap for metal recovery, solution make-up and recycle.

In most cases, the thin-layer process was used where crushed ores (80% −0.5 in) were stacked in heaps of 3–8 m height after agglomeration and sprayed at flow rates of 6–40 L·hour −1 ·m −2 with 15–90 days duration for copper oxides and 10–18 months for sulfides. Of note, 80%–85% copper extraction was commonly achieved.

The process of extracting copper from copper ore varies
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 extraction
Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).

copper, which are also found in ore deposits of copper, can be converted into a soluble form by leaching, where the chemistry of the process is simple. Copper carbonates and oxides, are present mainly in the oxidation zone
Hence, it is essential that the chemical composition of each copper production stage is known for conducting these studies, which may be challenging due to the huge variability of concentration data concerning the ore extraction region, the process type, and the operational conditions.

Extraction Of Copper From Copper Pyrite
The principal ore of copper is copper pyrite and copper is extracted from this ore. The different steps in extraction of copper are: Crushing and concentration: The ore obtained from mines are broken down into small piece by jaw crusher and then pulverized. The ore being sulphide ore is concentrated by froth floatation process.

Turning Copper Ore into Copper: What are the Processes?
The process of extracting copper for its ore is quite complex and varied. It largely depends on the type of ore in question, particularly whether it is a sulfide or oxide type. Copper mining has typically been performed through open-pit mining, where stepped benches are dug deeper and deeper into the ground over time.
