(Iron ore, hardwood trees, limestone and water) Iron ore is a rock that contains a certain amount of iron but mixed with various silicates and oxygen atoms. In 1792 Centre Furnace began manufacturing iron by filling the 35 foot furnace stack with charcoal and sending a blast of air through the furnace with use of bellows powered by a water wheel.
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 (waterrepel) 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.
