Application of placer gold morphology to gold exploration
, 2017 Placer gold undoubtedly carries some of the features of endogenous gold. The physical and chemical characteristics of such gold are influenced by many factors: the nature of the primary gold, the water force, the morphology of the river bed, the length of transport and the chemical composition of the water in the river. In the Republic of Macedonia has

Advanced Engineering Materials, EarlyView.Carbon‐free inert anodes are essential for decarbonizing aluminum electrolysis. This study investigates a recyclate‐based MgO‐316L steel composite anode tested under galvanostatic Hall–Héroult conditions in cryolite at 1000°C. Microstructural analysis reveals selective MgO fluorination, spinel and oxide layer formation, electrolyte infiltration, and ...
