What reading level is The Analysis of Minerals And Ores of the Rarer Elements for Analytical Chemists book?
To quickly assess the difficulty of the text, read a short excerpt:
(y) Determination of the Magnetic Susceptibility 1 is said to be a rapid and useful method.
(4) The Separation. The procedure tabulated below, which will give the best possible results in the shortest time, is substantially that worked out by C. James. 2 The thorium having been removed by one of the methods described under Thorium, III. , the rare earths in the filtrate are precipitated hot with caustic soda, the precipitate dissolved in hydrochloric acid, the solution precipitated with oxalic ...acid, and the precipitate ignited to oxides. The further treatment depends on the proportion of yttrium earths present : if this exceeds 20 per cent. , the mixed oxides are dissolved in hydrochloric acid and the analysis proceeded with as under (a) ; if well below 20 per cent. , the procedure should commence at (/3). It should be kept in mind that these operations do not give a quantitative separation, as it is impossible entirely to eliminate the intermediate fractions between two elements ; but these may be reduced to small amounts.
