Microbial ore leaching (bioleaching) is the process of extracting metals from ores with the use of microorganisms. This method is used to recover many different precious metals like copper, lead, zinc, gold, silver, and nickel. Microorganisms are used because they can: lower the production costs. cause less environmental pollution in comparison ...

iron ore is expected to rise by more than 200 million tonne per year to meet the internal demand export. This additional requirement of iron ore will need beneficiation of low grade ore/fines to get the major portion of increased demand. This paper deals in brief to use of available methodologies for beneficiation of iron ore in Indian context.

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 iron in the chalcopyrite ends up converted into an iron (II) silicate slag which is removed. Most of the sulfur in the chalcopyrite turns to sulfur dioxide gas. This is used to make sulfuric acid via the contact process (copper extraction and purification). Overall equations for these series of steps are:
