The shape factor of the iron ore concentrate was evaluated through the sphericity function (Ψ) and determined by the permeametry method [45] for the bulk concentrate and for the sample after 90-h pumping. To distinguish the iron and quartz particles, dried ore samples were mounted in bakelite, polished to 1 μm, coated with carbon and examined ...

An Ore is a naturally occurring material in shape of rock which contains a metal compound. When extracted from the mine ore is typically crushed, ground and run through a beneficiation process to produce enriched ore called Concentrate .One of the most widely used ore beneficiation process is called froth flotation where the minerals are separated from each other.

Low-grade iron ores are finely ground and processed to recover iron-bearing minerals. However, the iron-rich powder is too fine to be used directly in blast furnaces and most direct reduction furnaces, and must be agglomerated or pelletized into a usable product called "pellets." Bentonite clay has traditionally been used as a binder to make iron ore concentrate pellets, but it is ...

The main goal is to use this data to predict how much impurity is in the ore concentrate. As this impurity is measured every hour, if we can predict how much silica (impurity) is in the ore concentrate, we can help the engineers, giving them early information to take actions (empowering!). Hence, they will be able to take corrective actions in advance (reduce impurity, …
