An Overview of Beneficiation and Hydrometallurgical

09 09 2019  In some cases ore beneficiation is not considered necessary and/or economical However this does not mean value cannot be extracted from the ore via other methods such as implementing a direct chemical decomposition of the mineral Forgoing beneficiation techniques with some ores such as eudialyte group minerals may be more economical.

What is Beneficiation

The goal of beneficiation is to eliminate inefficiency and waste by ensuring that as much recoverable material as possible is extracted from ore A number of techniques can be used for this often starting with grinding the ore into particles Once ground the particles can be sifted and sorted to extract usable material and set waste aside.
