3. CP-A is the main raw material of natural rutile and synthetic rutile is a natural rutile rutile ore mining, beneficiation obtained by the production of natural rutile rarely and only for the use of supplementary material in place resource.    Third, the market situation and development trend of titanium raw materials    Fourth, domestic chlorination raw materials Industrial plug valves are wildly used in oil tank or any type of chemical industry pipeline system. DBB Plug Valve and Sleeved Plug Valve with ASME & DIN standard are commonly used by customer. Industrial Plug Valve are with soft and metal seal type and valve size are from 1/2 inch to 24 inch(DN15-DN600) matching pressure from class 150 to class 600(PN10-PN100) which are suitable for operating in the working media temperature from -29℃ to 180℃, as well as material in carbon steel, stainless steel, alloy steel and duplex steel in casting material.

The main source of CP-A is synthetic rutile, a rutile-type high-grade titanium-rich material to remove iron titanium ore iron grains obtained. The most typical UGS slag, such as QIT of Canada.
The production methods of synthetic rutile include electrothermal method, reduction rust method, hydrochloric acid leaching method, and sulfuric acid leaching method.
The process characteristics of various production methods are shown in Table 6. [next]
As a raw material for chlorination, it has been restricted by environmental protection. In recent years, CP-B and CP-A have developed rapidly. According to statistics, in 2000, natural titanium minerals accounted for 44% of the total raw material supply, and the rest were artificial titanium-rich materials. The total supply is 45.78 million tons / year, of which the raw materials available for chlorination, illuminate, phosgene 641,000 tons, natural rutile 390,000 tons, artificial titanium-rich material 2,534,000 tons , a total of 3573 million tons. Artificial titanium-rich materials accounted for 78% of the total supply. It can be seen that the raw materials used in the chlorination process are still very rich.
At present, the global titanium slag production capacity is 3 million tons / year, the largest supplier is Canada's QIT company. The production capacity of synthetic rutile is 10.0 million tons/year; the production capacity of Western Australia's Aluka uses Becher process is up to 480,000 tons/year.
The standard for synthetic rutile is shown in Table 7. [next]
The domestic electric furnace smelting high-titanium slag has a low production capacity of about 40,000 tons/year. The amount of titanium chloride used in chlorination is 19,000 tons, and the production of high-titanium slag for sponge iron and fine TiC1 4 is 20,000 tons. The high-titanium slag smelting electric furnace has a maximum of 7500kV·A and a small furnace of 1800kV·A. The increase in the production capacity of domestic chlorination titanium white and sponge titanium will drive the development of high titanium slag production plants.
For reasons of cost, the sulfuric acid titanium dioxide enterprise is not interested in acid-soluble titanium slag, resulting in no domestic production of acid-soluble titanium slag. With the implementation of the clean production method, the production of acid-soluble titanium slag by the sulfuric acid process will be mentioned on the agenda.
After many years of research and development, the rutile and high-quality high-titanium slag suitable for CP-A have not yet formed actual production capacity, and it cannot provide raw materials for large-scale and stable production of chlorination process.
