6. Production of titanium.

1. In the process for producing sulfuric acid titania we offer advantageous method of producing sulfuric acid from the production of titanium dioxide iron oxide, sulfuric acid and fertilizers.

2. In the production of titanium sponge chlorine way we can offer a profitable way to processing of these waste to produce the desired products and fertilizers.

3. There is a method for the selective chlorination of ilmenite in the absence of a reducing agent at 600-1000 ° C. We can offer advantageous to regenerate chlorine and getting it simultaneously in the production of chlorine-free fertilizer without electrolysis at deemed price.

4. Titanium tetrachloride is prepared by melting a titanium raw coke to yield titanium slag and pig iron. On waste tone receive about 400-500 kg 300-400 kg slag and iron. The slag was chlorinated in the melt at 900-1000 ° C. Chlorination get TіSl4, gas and solid waste. We can offer low-temperature chlorination process titanium with simultaneous obtain chlorine-free fertilizers. This operation will allow even exclude high-temperature recovery process titanium magnesium (sodium), and energy-intensive electrolysis of magnesium (sodium) for titanium metal.

5. There is a low temperature process for producing titanium tetrachloride. Ilmenite ore is treated with sulfuric acid, iron sulfate obtained are separated. On cooling to 0 ° C the solution was saturated with hydrogen chloride and potassium chloride is added. In is precipitated hlortitanat potassium. By heating it to 300-500 ° C was prepared by titanium tetrachloride vapor and the precipitate (potassium chloride) is recycled into the process. The resulting titanium tetrachloride is of high quality.

Disadvantages of the method are having problems:

- Refining the obtained iron sulfates;

- separating the resulting potassium chloride by sulfuric acid;

- Providing process hydrogen chloride and sulfuric acid.

We can offer low-temperature waste-free process for the preparation of titanium tetrachloride, which eliminates above drawbacks.

6. There is a process, wherein the titanium raw materials is first is treated chlorine at a temperature of 300-4000 C to give ferric chloride which is used as a commodity, or is treated oxygen at a temperature of 1000 ° C to obtain iron oxide and chlorine. Titanium dioxide is processed by known methods in the titanium tetrachloride. This method of regenerating chlorine highly costly and energy-capacious.

We can receive from any chloro chlorides including iron chloride and therefore can offer a new technological process of production of replacing it with titanium - regeneration of chlorine.

This will give an opportunity to get additional economic benefit.
