the iron ore. Around 150 million tons of good quality iron ore reserves had been identified in Chiniot. The field survey based on the cores recovered from several drill holes of the ore body has shown that the ore occurs in bands ranging from one meter to several meters in thickness. The Chiniot iron ore is predominantly

THE BAUXITE PURIFICATION PROCESS1} Chemical purification of raw materials to form a high purity alumina. 2} Reduction of alumina. STEP 1 : PURIFICATION TO FORM HIGH PURITY ALUMINA There it is purified to alumina using the Bayer process which is based on the fact that silica is an acidic oxide, alumina is amphoteric and both iron oxide and ...
Various Zones differ significantly, which may limit the applicability of a particular process to only part of the ore reserves. Processing routes must be able to reject the large iron, silica and magnesia contents. High iron content is a problem for acid leaching processes in general. Magnesia and alumina are also acid consumers.

solventextraction or ionexchange. The uranium industry was the first hydrometallurgical industry to make extensive use of these two unit operations. The active agent in the solventextraction process is usually an organic amine salt, diluted in kerosene, that can selectively extract the uranium ions into an organic complex which is insoluble ...
The pig iron was melted in a running out furnace and then run out into a trough. This process oxidised the silicon to form a slag, which floated on the iron and was removed by lowering a dam at the end of the trough. The product of this process was a white metal, known as finers metal or refined iron.
Pyro metallurgical extraction of Zinc Presently about 15 20% of the world's zinc production comes from pyrometallurgical route. The horizontal and vertical retort processes and electrothermal process were used in the past for zinc production but have become obsolete due to high power consumption and low recovery.

2 Brief Introduction To The Extraction Of Iron Metal Mining and processing iron ore is a multistaged, labourintensive process that begins with the extraction of raw iron ore from the ground, continues with the transformation of that raw material into a completed product, and concludes with the delivery of that product to end users.
Iron is the most vital metal in human use. It constitutes % of the crust material and holds third position in abundance after silicon and aluminium. It is rarely found in native condition except in meteorites and some eruptive rocks. It enters into large number of rocks forming silicates and is widely available as oxides.

Introduction The production of iron from its ore involves a redox reaction carried out in a blast furnace. The furnace is filled at the top with the iron ore oxide most commonly hematite ( F e 2 O 3) but can also magnetite ( F e 3 O 4 ), carbon called coke and limestone ( C a C O 3 ).

The process begins by removing the topsoil from the area to be mined. This soil is then replaced and compacted to make sure that there is no waterlogging or runoff. The next step is to drill holes into the rock, so that explosives can be inserted. The explosives are set off, and the iron ore is blasted out of the rock.
This type of foundry started in 1 060 The primitive smelting of iron was done in extremely hot ovens. The temperature and ventilation in the ovens were controlled. After the iron had melted, the iron would harden and then hammered to get rid of the silt. Afterwards, it was processed and cut into sheets.
The extraction of iron ore involves surface (openpit) or underground mining techniques (please refer to Chapter 7 (Stace, 2015) on Iron Ore Extraction Techniques).
