The process isolates the impurities that concentrate in the molten zones, leaving the portions behind them somewhat more pure. This process is repeated until impurities are moved to the end of the rod and cut off, resulting in an almost completely pure metal rod. Figure (PageIndex{4}): The Zone refining method. from Binod Shrestha.
The blast furnace is a counter-current gas/solids reactor in which the descending column of burden materials [coke, iron ore and fluxes/additives] reacts with the ascending hot gases. The process is continuous with raw materials being regularly charged to the top of the furnace and molten iron and slag being tapped from the bottom of the ...
It accounts for approximately 70% of the total known reserves, and therefore is an essential source of copper (Ahn, Wu, and Lee 2022;Taskinen et al. 2019;Tian and Liu 2022;Watling 2013).

The blast furnace uses coke, iron ore and limestone to produce pig iron. Coal traditionally has been a key part of the coke-making process. The coal is crushed and ground into a powder and then charged into an oven where it is heated to approximately 1800°F in the absence of oxygen. As the oven is heated, the coal begins to melt so most of the ...
