Based on its appearance in the field, the substance was initially thought to be molybdenite (the mineral from which Re was first extracted), but after analysis back in the laboratory it was found ...
These superalloys are used in the combustion chambers, turbine blades and exhaust nozzles of jet engines, where they must withstand extreme conditions. Rhenium is obtained from molybdenite in porphyry ...
Molybdenite (Molybdenum Disulphide); (7) Galena (Lead Sulphide); (8) Carborundum (Artificial Silicon Carbide) . The Electrolytic Detector, perhaps the most widely known type, appears in many forms ...
Despite not reaching the target depths, the drilling confirmed the presence of classic copper porphyry alteration from propylitic to potassic along with a zonation of sulphide mineralization, from a ...
molybdenite and quartz-chalcopyrite veinlets discovered at depth. The entire hole was mineralised with copper grades ranging from 0.02 per cent to 0.1 per cent, increasing with depth. Sarytogan ...
