Copper Mining and Extraction Sulfide Ores

Copper can be extracted from its ore by: Underground: sinking a vertical shaft into the Earth to an appropriate depth and driving horizontal tunnels into the ore. Open pit: 90% of ore is mined by this method. Ores near the surface can be quarried after removal of the surface layers.

12.3 Primary Copper Smelting

(green feed) ore concentrate produces matte, a molten mixture of copper sulfide (Cu2S), iron sulfide (FeS), and some heavy metals. Converting the matte yields a high-grade "blister" copper, with 98.5 to 99.5 percent copper. Typically, blister copper is then fire-refined in an anode furnace, cast into

This car, MWCX 200475, is a good example of the modern gondola on today's railways, having been built in early 2015.


dried to form a powder (copper concentrate). This process is usually able to recover 85 to 95 percent of the copper in the ore. At this point the dried concentrate contains approximately 20-30 percent copper by mass, around 30 per cent iron, 30 per cent sulphur, with the remainder including small amounts of gold, silver, and unwanted elements such

Afghanistan's mighty copper reserves remain out of reach ...

Aug 24, 2021· Afghanistan's mighty copper reserves remain out of reach, even for China. As the world's media spotlight falls on Afghanistan, Fastmarkets looks at why reported claims of incoming Chinese mining deals are unlikely to be fulfilled soon. Mes Aynak, Afghanistan's most well-known copper project, means "small copper deposit" in Pashto.

Froth Flotation of Iron Ores

Jan 02, 2012· With the depleting reserves of high-grade iron ore in the world, froth flotation has become increasingly important to process intermediate- and low-grade iron ore in an attempt to meet the rapidly growing demand on the international market. In over half a century's practice in the iron ore industry, froth flotation has been established as an efficient method to remove impurities from iron ore.

How to remove Iron Minerals from Gold Concentrate

Apr 01, 2011· This is called concentrate that must be further concentrated by the removal of the iron oxides. It is a good idea to treat the concentrate with either vinegar or muriatic acid because the gold in the concentrate is often coated with a thin film of iron or manganese oxide giving it the appearance of ordinary black sand.
