Physical methods of iron ore concentration


Internet of Things and anomaly detection for the iron ore ...

More specifically, we focused on improving the quality of the output in a data-driven iron ore concentration factory. In this plant, mined iron ore goes through a series of complex physical and chemical transformations so as to increase the concentration in iron and reduce the concentration in impurities such as silica.

Pre-concentration of nickel in laterite ores using ...

Sep 01, 2019· This paper examines the effects of different physical methods on pre-concentration of nickel in laterite ores. The effect of ore mineralogy on choosing the best strategy to upgrade nickel will be discussed. The findings of this project will help to unlock a substantial volume of nickel with significant value from laterite ores.

So, we can say that in the concentration of ore, we remove gangue from the ore mined from the Earth's surface. This process is called concentration of ores as the removal of impurities increases the percentage of metal. It is also known as dressing of ores. This process is done by using the physical and chemical methods; The methods used in the ...
