To quickly assess the difficulty of the text, read a short excerpt:
The principal sources of error in the estimation of titanic acid in iron ores are the tendency of P 2 O 5 to prevent the precipitation of TiO 2 by boiling, when its sulphuric acid solution contains P 2 O 5 and ferrous sulphate, and the liability of A1 2 O 3 to separate out with the TiO 2 when the latter is precipitated under the circumstances above mentioned. There is also a mechanical difficulty, caused by the adhesion of the precipitated TiO 2 to the bottom and sides of the beaker, from which... it can sometimes be ANALYSIS OF IRON ORES. JQIJ removed only by boiling with a strong solution of caustic potassa. The admirable series of experiments carried out by Dr. Gooch* on the separation of aluminium and titanium suggests a method which renders the determination of TiO 2 in iron ores much less troublesome, while adding greatly to the accuracy of the results. In carrying out the details of the method, dissolve 5 or 10 Details grammes of the ore in HC1, and proceed exactly as in the deter- method, mination of P 2 O 5, by fusing the residue from the treatment of the insoluble matter by HF1 and H 2 SO 4 and the acetate precipitate, with Na 2 CO 3 and a little NaNO 3, f and then complete the operation exactly as described in the determination of Ti in pig-iron.
