Abstract

Fremgangsmåte for fremstilling av høyverdig titandiok-sid ved svovelsyre-oppslutnlngsfremgaiigsmåten ved omsetning av llaenlt og/eller tltanholdlg slagg med konsentrert svovelsyre, opplesning av den faste oppslutnlngsmassen med metallsulfat-holdlg vandig svovelsyre og eventuelt vann og reduksjon av det treverdige Jernet og frasklllelse av den uopplasllge råstoffandelen for fremstil Ung av en fremmedmetall-salt-rlk svovelsyreholdig tltanylsulfatoppløsnlng, 1 det videre betegnet svartoppløsnlng, hydrolyse av svartoppløsnlngen med etterfølgende adsklllelse av det utfelte tltanoksydbydratet. Intens vasking med vann, tørking og eventuelt kalslnerlng, hvorved svartoppløs-nlngen før hydrolysen bringes 1 kontakt med et organisk medium, 1 det følgende betegnet "eketraksjonsmlddel", og tllbakeekstraksjon, 1 det videre betegnet "stripping", av den derved dannede organiske fasen ved hjelp av vann og/eller en vandig løsning Inneholdende svovelsyre og/eller tltanylsulfat under tilbakeføring av den derved oppnådde organiske fasen 1 ekstraks]onen, hvorved det for oppløsning av den faste oppslutnlngsmassen anvendes den ved ekstraksjonen dannede metallsulfat-boldlge svovelsyren, betegnet ekstraksJonstynn-syre.
