What is beneficiation in mineral processing - MINERALLURGy

Beneficiation can significantly increase the concentration of valuable components. The content of important non-ferrous metals – copper, lead, zinc – in ores is 0.2-2.5%, and in their concentrates – 30-70%. Tungsten from 0.1-0.2% to 45-65%, molybdenum concentration increases from 0.1-0.07% to 46-50%, coal ash decreases from 24-34% to 3-14%.
