Processes - extraction, mining, smelting, refining ...

Open-pit – 90% of ore is mined using the open pit method. Ores near the surface can be quarried after removal of the surface layers. The ore An ore is a rock that contains enough metal to make it worthwhile extracting. Grinding The ore is crushed, then ground into powder. Concentrating The ore is enriched using a process called froth flotation. Unwanted material (called gangue) sinks to the bottom and is

Mining and Extraction: Oxide Ores - processes for ...

The process used to treat sulfide copper ores begins at the mine site, where the copper-bearing minerals are physically separated from the rest of the rock. The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining. The smelting stage gives the name pyroprocessing: processing

Extraction of Crude Metal from Concentrated Ore ...

01/04/2020  The process of extraction of metal by reduction of its oxide with carbon (in the form of charcoal, coke or carbon monoxide) is called smelting. The roasted ore is mixed with a suitable amount of carbon (coke or coal) or carbon monoxide and heated to a high temperature above the melting point of the metal in a furnace.

Extractive metallurgy - Wikipedia

Extractive metallurgy is a branch of metallurgical engineering wherein process and methods of extraction of metals from their natural mineral deposits are studied. The field is a materials science, covering all aspects of the types of ore, washing, concentration, separation, chemical processes and extraction of pure metal and their alloyingto suit various applications, sometimes for direct use as a finished product, but more often in a form that requires further working to achieve the given properties to suit the applicat
