摘要： A process is provided for the production of titania rich slag from ilmenite. The ilmenite is fed together with carbonaceous reductant, and in the absence of fluxes, to the molten bath of a DC arc furnace. The molten bath of the furnace forms the anode and one or more electrodes in the roof of the furnace forms the cathode. A frozen lining is established and maintained between the refractory lining of the furnace and the molten bath and the process includes means to control the thickness of the frozen lining as well as the whole smelting process.

摘要： An improved process for the production of synthetic rutile from ore containing titanium and iron, such as ilmenite ore, by a multi-step procedure employing controlled reduction, controlled oxidation and acid leaching. More specifically, the ilmenite ore first is reduced thermally such that substantially all of the iron (III) present has been converted to iron (II) and some metallic iron. The reduced ore then is oxidized with an oxidizing gas substantially free of elemental oxygen to convert the metallic iron to iron (II) without the substantial formation of iron (III). The oxidized ore then is leached to remove the iron (II) and calcined to produce synthetic rutile. The synthetic rutile so produced contains in excess of 92 percent titanium dioxide and less than 2 percent iron (III), by weight. Often, the synthetic rutile contains less than 1 percent total iron by weight.

摘要： THE SMELTING OF AN ILMENITE CONCENTRATE (61 WEIGHT PERCENT TIO2 AND 37 WEIGHT PERCENT FEO) WITH A SODIUM BORATE FLUX AND A CARBONACEOUS MATERIAL, SUCH AS COAL, AS THE REDUCING AGENT, IS PERFORMED IN A FURNACE AT 1150*C. TO 1200*C. TO YIELD MOLTEN PIG IRON IS MARKETABLE CONDITION (95 TO 97 WEIGHT PERCENT IRON) ANC SLAG CONTAINING 25 WEIGHT PERCENT TITANIA (TIO2) AND LESS THAN 1 WEIGHT PERCENT FEO, WITH THE SLAG CONTAINING 95 TO 99 PERCENT OF THE TIANIUM. TWO ALTERNATIVE PROCEDURES ARE THEREAFTER FOLLWED, ONE A QUENCHING-LEACHING AND THE OTHER A LEACHING-CALCINATION PROCESS, TO YIELD A SODIUM TITANATE PRODUCT CONTAINING 70 TO 80 WEIGHT PERCENT TIO2, A PRODUCT WHICH CAN RADIALY BE EBEFICIATED TO PIGMENT GRADE TIO2 BY SUITABLE TREATMENT, SUCH AS BY THE WELL KNOWN "SULFATE PROCESS".

摘要： Provided is a method for preparing rutile from acid-soluble titanium slag, including: grinding acid-soluble titanium slag; adding a sodium carbonate modifier, and performing microwave irradiation treatment in a microwave device; adding an ammonium bifluoride additive; and performing acid purification and calcination to obtain rutile. By means of a microwave heating mode, the equipment investment needed by the method is low, and the energy consumption is low. The purity of artificial rutile is more than 91%, byproducts are fewer, and the environmental pollution is low.

摘要： The present invention provides a method and apparatus for the controlled synthesis of nanoparticles using a high temperature process. The reactor chamber includes a high temperature gas heated by means such as a plasma torch, and a reaction chamber. The homogenizer includes a region between the reactant inlets and the plasma (the spacer zone) to ensure that feeds from the reactant inlets are downstream of the recirculation zone induced by the high temperature gas. It also includes a region downstream of the reactant inlets that provides a nearly I dimensional (varying only in the axial direction) flow and concentration profile in the reaction zone to produce nanoparticles with narrow size distribution.

摘要： An improved process for producing titanium dioxide by reacting a titanium dioxide ore with chlorine to produce a gaseous stream containing titanium tetrachloride, condensing titanium tetrachloride from the gaseous stream containing titanium tetrachloride to produce chlorinator tail gas, vaporizing the condensed titanium tetrachloride, reacting the vaporized titanium tetrachloride with oxygen to produce a gaseous stream containing titanium dioxide particles and chlorine, separating the titanium dioxide particles from the gaseous stream containing titanium dioxide particles and chlorine to produce burner tail gas, analyzing the chlorinator tail gas for residual chlorine to control the step of reacting the titanium dioxide ore with chlorine, analyzing the burner tail gas for oxygen to control the step of reacting the condensed titanium tetrachloride with oxygen. The improvement is to analyze the chlorinator tail gas for residual chlorine (and/or the burner tail gas for oxygen) using an on-line analyzer.
