The second step involves either smelting or leaching to remove a large proportion of impurity particularly iron and in the case of sulfides ore, sulphur. The final step, refining, removes the last traces of the impurity elements and produces a copper product of percent purity (McGrawHill Encyclopedia, 1998).

Refining requires 4 crystals (so now, its 2 crush cycles to 1 refine cycle) and produces 4 purified chunks. Sorting requires 9 purified chunks, which means 3 refine cycles, which means 6 crush cycles. This produces 3 iron, 2 copper, 1 quartz, 1 nickel, 1 titanium, and 1 zinc. 6 crush cycles, which is 12 saphirite ore units, turns into 3 iron ...

Iron is concentrated by the process of calcinations. Once it is concentrated, the water and other volatile impurities such as sulfur and carbonates are removed. This concentrated ore is then mixed with limestone (CaCO 3) and Coke and fed into the blast furnace from the top. It is in the blast furnace that extraction of iron occurs.

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 highertemperature refractories and the increased cooling required to accommodate the higher operating temperatures in nickel production.

The complete process of extraction consists essentially of enriching this matte to approximately 65 per cent content of platinum metals and then treating this concentrate with acids to separate the individual platinum group metals from each other, followed by final refining. Operations to achieve this can roughly be divided under three headings:

Six steps to process iron ore. 1. Screening. We recommend that you begin by screening the iron ore to separate fine particles below the crusher's CSS before the crushing stage. A static screen is used to divert the fine particles for crushing. This step prevents overloading the crusher and increases its efficiency.

Iron ore consists of oxygen and iron atoms bonded together into molecules. To create pure iron, one must deoxygenate the ore, leaving only iron atoms behind, which is the essence of the refining process. To coax the oxygen atoms away from the ore requires heat and an alternate atomic partner for the oxygen to bond to.

The raw materials mix or "charge" enters the furnace from the top and hot air is blown or blasted from the bottom causing the coke to burn and the oxygen to combine with carbon in the coke to form carbon monoxide. Now, this carbon monoxide that is unstable, reacts with the ore to form carbon dioxide and iron. The Separation Of Iron.
