Abstract
A method for refining metal slag containing TiO.sub.2 to produce titanium compound comprising introducing molten slag into a heat vacuum chamber, whereby the heat and vacuum oxidize the slag. The slag is skimmed or further reacted by application of heat and vacuum to remove additional impurities.
Claims11
A physical method for refining titanium ore comprising the steps of:
- reducing titanium ore to TiO.sub.2 and Fe;
- subjecting said reduced titanium ore to a single vacuum heat process which causes said TiO.sub.2 to separate from said reduced titanium ore;
- and
- separating said TiO.sub.2 from said reduced titanium ore.
A physical method for purifying slag comprised of TiO.sub.2, comprising the steps of:
- introducing said slag in molten form into one heat vacuum chamber, the heat and vacuum in said chamber being such as to remove impurities by high pressure volatization from said slag;
- skimming or otherwise removing impurities from the top f said slag;
- and
- removing said TiO.sub.2.
A physical method for refining slag, said method comprising the steps of:
- introducing slag containing TiO.sub.2 into a first vacuum heat chamber wherein the vacuum and heat in said chamber causes the removal of impurities from said slag by volatilization;
- skimming said slag or reacting said slag with a base melt to form volatile suboxides;
- removing TiO.sub.2 from said slag.
A physical method for producing TiO.sub.2 in a single vacuum heat chamber from slag comprising TiO.sub.2 comprising the steps of:
- exposing molten slag containing TiO.sub.2 in said vacuum heat chamber to between 10 to 10.sup.-4 Torr;
- removing impurities from the top of said slag;
- collecting at the bottom of said furnace heavier elements of said slag such that between said collecting and said removing remains liquid TiO.sub.2 which is removed.
