Relating the Mineralogical Characteristics of Tampakan Ore to Enargite Separation [PDF]

open access: yesMinerals (Basel, Switzerland), 2017
The mineralogical characteristics of enargite-bearing copper ores from the Tampakan deposit have been investigated as the means to understanding the separation of enargite from other copper sulphides (chalcopyrite and bornite). It was found that a separation of these minerals was possible after grinding the ore samples to a P80 of 90 microns; enargite ...
