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.Process for the production of high-grade titanium dioxide by the sulfuric acid digestion process by reacting the ethylene and / or titanium-containing slag with concentrated sulfuric acid, dissolving the solid digestion mass with metal sulphate-containing aqueous sulfuric acid and, if necessary, reducing the water value The proportion of raw material for the preparation of a foreign metal-salt-rich sulfuric acid-containing titanyl sulphate solution, hereinafter referred to as black solution, hydrolysis of the black solution with subsequent separation of the precipitated titan oxide oxide. Intensive washing with water, drying and optionally calcination, whereby the black solution before the hydrolysis is brought into contact with an organic medium, hereinafter referred to as "extraction agent", and back-extraction, hereinafter referred to as "stripping", of the organic phase thereby formed by by means of water and / or an aqueous solution Containing sulfuric acid and / or trianyl sulphate while returning the organic phase 1 extract thus obtained, whereby the metal sulphate-bulbous sulfuric acid formed by the extraction is used to dissolve the solid digestion mass. .
