  • What's the function of limestone and Coke when added to ...

    The coke is a source of carbon monoxide which will reduce the iron oxide in the ore to iron and the carbon monoxide oxidizes to carbon dioxide. The limestone acts as a flux to remove other impurities and help the iron physically separate from the rest of the burden. It comes out carrying a lot of the other impurities as slag.

  • Froth Flotation Process - Mineral Processing & Metallurgy

    The Froth Flotation Process is about taking advantage of the natural hydrophobicity of liberated (well ground) minerals/metals and making/playing on making them hydrophobic (water-repel) individually to carefully separate them from one another and the slurry they are in. For this purpose we use chemicals/reagents: Frothers (MIBC) is what allows the formation of air bubbles.
