Ore is an aggregate of minerals and contains valuable and gangue minerals .The mineral beneficiation involves separations of gangue minerals from ore and is done in the following two stages:

1. Liberation of valuable mineral by size reduction technologies. In most ores the valuable minerals is distributed in the matrix of ore.  

2. Concentration technologies to separate the gangue minerals and to achieve increase in the content of the valuable mineral to increase the metal grade

Typical beneficiation processes include crushing, roasting, magnetic separation, flotation, and leaching.

We pass the raw material at different speed and angles to allow the impurities to liberate. Sometimes crushing it further to finer sizes make it possible.

Resources are limited, and they have formed after millions of years of evolutions and a result of so many atmospheric changes such as Volcanic deposits and earth crust movements.

Gold / Diamond / Copper / Lithium etc all are found in a raw manner where we need to beneficiate all the minerals to get our desired output. In Early 1980s we were throwing away Fe 62-63 Grade ore as dump, today we have to ensure to maximise what we can and preserve the balance for future.

Ethically its wrong to discard what Mother Earth has given us, so we should use what we can and preserve the rest.
