The commonest ore used in the extraction of copper is Chalcopyrite (CuFeS 2) also known as Copper Pyrites and other such sulphides. The percentage of copper in the actual ore is too low for direct extraction of copper to be viable. The concentration of ore is required and it is done by the Froth Flotation method. Concentration of Ore:
The symbol equations for the different stages of the extraction of iron from hematite are: Zone 1: The burning of carbon (coke) to provide heat and produce carbon dioxide:; C (s) + O 2 (g) → CO 2 (g). Zone 2: The reduction of carbon dioxide to carbon monoxide:; CO 2 (g) + C (s) → 2CO (g). Zone 3: The reduction of iron(III) oxide by carbon monoxide:

Nickel processing - Extraction, Refining, Alloying: The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used. The major differences in equipment are the use of higher-temperature refractories and the increased cooling required to accommodate the higher operating …
According to the phases present at room temperature, titanium alloys are divided into different main groups (see Fig. 1, top line), starting with CP-Titanium (commercially pure titanium, containing low amounts of oxygen, iron, nitrogen, and carbon only), consisting of nearly α-phase. α- and near-α-alloys are composed of α-phase …

The primary chemical reaction for reducing iron ore to iron is represented by: Fe 2 O 3 + 3CO → 2Fe + 3CO 2. This reaction illustrates how carbon monoxide acts as a reducing agent, converting the iron(III) oxide (rust) to metallic iron, whilst itself turning into carbon dioxide in the process.

Dry beneficiation capacity will increase by around 110 Mta. An important role is being played by projects for iron ore concentrate extraction by means of dry magnetic separation (Fig. 16). Three projects with a total of 9.6 Mta are already in the construction phase, another project with 8.5 Mta capacity concerns the production of iron ore pellets.
Being less dense, the slag floats on top of the iron. Slag and iron are tapped at regular intervals through separate tap holes. For merchant pig iron production, the iron is cast into ingots; in integrated steel mills, the molten iron or hot metal is transferred in torpedo ladle cars to the steel converters.
silicon (27.7%). Iron is third at about 5%. Metallic aluminum is not found in nature; it occurs in the form of hydrated oxides or silicates (clays). The principal ore from which aluminum is extracted is called bauxite after the town of Les Baux in southern France where the ore was originally discovered. Bauxite occurs mainly in the tropics and in

Cast iron. The molten iron from the bottom of the furnace can be used as cast iron. Cast iron is very runny when it is molten and doesn't shrink much when it solidifies. It is therefore ideal for making castings - hence its name. However, it is very impure, containing about 4% of carbon. This carbon makes it very hard, but also very brittle.
