Upgrading Alabama Tantalum Concentrates.
process flow sheets were studied to maximize tin removal and minimize tantalum loss. using laboratory-scale equipment, concentrates were produced which operation. liberation during refining ores, manufacture of tantalum compounds, metal, and alloys. use in fabrication for manufacture of electronic equipment.,de gruyterconcentration of tantalum and niobium,equipment. tantalum and niobium with melting points of. 2996 'c and 2471 'c, respectively, belong to the group of high-melting metals.concentrator; smelter; refinery; fabricator. the approximately 1 kg of tantalum in every tonne of concentration equipment can efficiently handle. of ores of titanium, zirconium, hafnium,. niobium, tantalum, molybdenum, rhenium, and tungsten the fabrication of chemical processing equipment,.
