GENERAL PRINCIPLE OF EXTRACTION prepareforchemistry

during the extraction of iron. Answer . During the extraction of iron, the reduction of iron oxides takes place in the blast furnace. In this process, hot air is blown from the bottom of the furnace and coke is burnt to raise the temperature up to 2200 K in the lower portion itself. The temperature is lower in

Leaching Copper Iron form Electrolyte

The removal of the iron appeared to offer the more attractive field. Briefly, the method followed involves leaching with sulphuric acid, removing a portion of the iron from the solution, and precipitating the copper electrolytically, Regarding the leaching per se, I do not think I could say anything which would be of any particular interest.
