Peak Shape Changes While Testing a Group of Samples. One common problem in HPLC analyses is a change in peak shape. Ideally, peaks should be symmetrical, with a Gaussian shape [D. R. Stoll, LC-GC N. Am. 39 …
Samples collected in tailing piles of a gravity plant were characterized in mineral composition, which shows in the heavy fraction the minerals spodumene, columbite-tantalite, ilmeno-hematite ...
example, Ta could be recovered by using a simple primary amide reagent.11 Niobium and tantalum are two transition metals almost always paired together in nature, with similar physical and chemical properties. Niobium has a high melting point, rela-tively low density, and important magnetic and super-conducting properties. Tantalum has a high ...
The two tailings products of Mozley Table samples are composed primarily of quartz (50%–52%), K-feldspar (17%–23%), muscovite (11%–14%), plagioclase (7%–14%), kaolinite (1%–2%), and …
The samples consisted of a mixture of minerals with tantalite as the major component, with minor amounts of microlite, quartz, mica, accessory garnet, and tourmaline.
About 10 kg of columbite tailings sample was obtained from different tailings dumps or deposits at the mine site using the grab sampling, coning, and …
