Separation of Titanium & Iron
Rose<r>1 says there is only one way by which the iron can be removed i.e by hydrosulphuret of ammonia & weak Muriatic acid[.] See Quarterly Journal of Science xvi p3812 - or Annales de Chemie xxiii, p3533.
Peschier4 gives a process by ferro prussiate of potash[.] See Quarterly Journal of Science xviii p1755 or the Bibliotheque Universelle xxvi p436[.]
Peschier on more particular processes. See Quarterly Journal of Science xix p 1577 or Annales de Chemie xxvii p288[.]
Dear Sir
I send you the above references[.] I do not know whether any of them will suit you. - I have sent the report to Major Kater9[.]
