28/07/2012· There are different steps involved in extraction of metals. Let us discuss them one by one: 1. Crushing and Grinding. First of all, ores are crushed into a fine powder in big jaw crushers and ball mills. This method is called pulverization. 2. Concentration Dressing of ores. The technique of removing gangue, the rocky impurities like Sio 2 present in an ore, is called concentration of an ore
The extraction of copper from ore is normally carried out in three major steps. The first step, mineral processing, is to liberate the copper minerals and remove waste constituentssuch as alumina, limestone, pyrite, and silicaso that the copper minerals and other nonferrous minerals of value are concentrated into a product containing .

An ore is a rock containing enough valuable mineral to make it worth extracting. In the case of copper, it is worth extracting when there is about 2 kg of copper per 1,000 kg of ore 0.2 . Copper minerals are found in over one hundred varieties, although only a few have been worked for copper on a large scale. The most abundant ores are chalcopyrite and bornite, which contain both copper and

Extraction of copper from sufidic ores, either by pyrometallurgy or hydrometallurgy, has various limitations. In this study, a solvometallurgical process for the extraction of copper from sulfidic ore minerals chalcopyrite, bornite, chalcocite and digenite was developed by usinganic lixiviant FeCl 3 as oxidizing agent and ethylene glycol EGanic solvent.
Subsequent steps depend on the nature of the ore containing the copper and what will be extracted. For oxide ores, a hydrometallurgical liberation process is normally undertaken, which uses the soluble nature of the ore minerals to the advantage of the metallurgical treatment plant.

In this lesson, you will learn about the different methods used to extract minerals from the ground and gain an understanding about how different types of mining affect the environment. How
Small, gas powered smelting furnaces can also be used to separate metal from ore. A cylindrical sheet metal container is built over a gas flame propane can also be used. Then,work of tubing is fitted around the smelter. The tubing includes a gas line, an air line, and other piping. A crucible usually made out of graphite or clay is used to dip into the smelter to extract molten metal
In heap leaching, the ore is placed on open air pads and the cyanide sprayed over it, taking several weeks to leach down to an impervious base. The solution then pours off the pad into a pond and is pumped from there to a recovery plant where the gold is recovered.

From ore to metal. What are ores? An ore is any naturally occurring source of a metal that you can economically extract the metal from. Aluminium, for example, is themon metal in the Earth's crust, occurring in all sorts of minerals. However, it isn't economically worthwhile to extract it from most of these minerals. Instead, the usual ore of aluminium is bauxite which contains
