Crushing in Mineral Processing

In mineral processing or metallurgy, the first stage of comminution is crushing.. Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wear-resistant plate/surface.

Iron ore pelletizing systems -

Iron ore can be upgraded to a higher iron ore content through beneficiation. This process generates iron ore filter cake which needs to be pelletized to be used in the steel making process. Also during the processing of high grade iron ores which don't need beneficiated, fines which are generated can be pelletized and used instead of being disposed of.

The Extraction of Copper - Chemistry LibreTexts

The iron in the chalcopyrite ends up converted into an iron(II) silicate slag which is removed. Most of the sulfur in the chalcopyrite turns into sulfur dioxide gas. This is used to make sulfuric acid via the Contact Process. An overall equation for this series of steps is: [2CuFeS_2 + 2SiO_2 +4O_2 rightarrow Cu_2S + 2FeSiO_3 + 3SO_2 label{1}]
