Kinetic study of ferrocolumbite dissolution in hydrofluoric acid medium

M.H. Rodriguez, +2 more
- 01 Mar 2007 - 
TL;DR: In this article, the authors investigated the degradation of ferrocolumbite with hydrofluoric acid solutions in a pressure reactor and found that the leaching rate of the mineral increases with the concentration of acid and the reaction temperature but is not affected very much by stirring speed.
Journal ArticleDOI

Determination of Nb, Ta, Fe and Mn by X-ray fluorescence

M. del C. Ruiz, +3 more
- 01 May 2002 - 
TL;DR: In this article, an analytical methodology was developed for the quantification of niobium, tantalum, iron and manganese in samples of ores and solid residues coming from ore pressure leaching, using different acids.
