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.
WhatsApp: +86 18838072829iron 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.
