Iron is the principal raw material for steel industries and Hematite is a principal ore of iron. Quantitative and qualitative estimation of iron in its ores is a crucial factor before its extraction. In this work, quantitative chemical analysis of iron was carried out from the collected seventytwo hematite samples from Pokhari, Nawalparasi.

The iron extraction rate in this step was merely 2%, while other impurities remained largely not extracted. Next, a fivestage countercurrent stripping step was performed using 4 mol/L H 2 SO 4 at 25 °C and an O/A ratio of 1/1 for 15 min, and in this step, more than 98% of the iron content was extracted and Sc loss was below 1%.

The ore slurry comes to the mix tank for mixing, and flotation by flotation machines. Lithium ore often contains complex components, and the lithium concentrate obtained by flotation sometimes contains more iron. In order to improve the grade of lithium concentrate, the magnetic separation method is used as an auxiliary method.

Iron is extracted from its ore, haematite, by reduction with carbon. This takes place in a blast furnace (named after blasts of air [20% oxygen], heated to 1000 °C, which are blasted into the bottom of the furnace): A mixture of crushed iron ore, coke (an almost pure form of carbon) and limestone is fed into the top of the blast furnace.

The wood was likely much larger originally, as extracting iron from its ore required great quantities of charcoal. Metal extraction also requires a lot of water to wash the ore, a need fulfilled with the Branlin river flowing at the foot of the hill. The ore also needed to be crushed, and that was done in appropriate mills.
