Dry magnetic separation (DMS) enables to separate the non-magnetic fraction of iron ores at the initial stage of their concentration and therefore to decrease cost of their further processing. However, a considerable amount of metal is lost in DMS tails at that.
In magnetic separation ore is carried over a conveyer belt which passes over a magnetic roller. If either the ore or the gangue is capable of being attracted by the magnetic field then it will collect near the roller and the particles showing non magnetic behaviour will be collected away from the roller.

In chemical separations, we can use thermodynamic models to predict the composition in each phase at equilibrium. For example, Raoult's Law describes the compositions of vapor and liquid phases at equilibrium. Mass transfer models help us understand how we can manipulate the process to reach equilibrium in a faster or more economical manner.
Since separations are ubiquitous in chemical plants and petroleum refineries, chemical engineers must be familiar with a variety of separation methods. We will first focus on some of the most common chemical engineering separation methods: flash distillation, continuous column distillation, batch distillation, absorption, stripping, and extraction. These separa …

Definition of Concentration of Ore. Ore concentration is the chemical process of eliminating impurities like sand, rocks, silt, grit etc. from the ore to extract the metals in their pure form. In other words, it is the method of separating ore from the gangue, as the gangue or matrix particles are the valueless substances that are of no use.
