Beneficiation
Beneficiation. In the mining industry or extractive metallurgy, beneficiation is any process that improves (benefits) the economic value of the ore by removing the gangue minerals, which results in a higher grade product ( ore concentrate) and a waste stream ( tailings ). There are many different types of beneficiation, with each step ...
GOLD
Based on the mineralogical characteristics and mineral processing techniques required, gold ores can be classified into the following types: Placers, quartz vein gold ores and oxidized ores: Generally, placers, quartz vein gold ores and oxidized ores are freemilling and gold can be recovered by gravity and/or direct cyanide leaching.
