MECHANOCHEMICAL REACTION IN PROCESS OF GRINDING GOLD ORE
(Department of Mining Engineering, Northeastern University, Shenyang110006)
Abstract: Because gold ore had undergone the action of powerful and lengthy mechanical force, the gold in ore concentrated in iron powder in the process of grinding. Observing the phenomenon through experiment and X-ray diffraction analysis, the result showed that mechanochemical reaction had taken place and it led to the mechanical combination between gold and iron.
