Mining is the basic process of making steel. It is the process of extracting iron ore minerals from the ground. Hence, option 'a' is incorrect. Pelletizing is one of the processes in making steel. It is the process of compressing or molding the iron ore material to the shape of the pellet. Hence, option 'b' is incorrect.
4. Beneficiation of Copper Ore. The next step in processing is called beneficiation. This is the first step in concentrating the copper into a more useable form. 5. Smelting and Extraction. The next step in the process flow is smelting for sulfide ore concentrate and solvent extraction for oxide ore leach solution. 6.
Mining - Underground, Safety, Techniques: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of …
A common method to mill the crushed rock is milling in large rotating drums with metal balls, grinding the rock to small particles and liberating ore and gangue minerals from each other. Milling is one of the most energy intensive steps in mining, accounting for most of the energy consumption at a mine. Separation and concentration

Open-pit mining technology. Open-pit mining clearly offers a number of economic advantages over underground mining, especially now that mineral-processing technology has advanced to the stage where very low-grade ores can be treated profitably. 100 to 150 years ago, this was not the case, and mining was still much more selective.
