Titanium Dioxide (TiO2) Production and Manufacturing Process

Feb 26, 2007· Calcium chloride has a strange reputation—it's probably the most used admixture for concrete and also the most controversial. On the positive side, CaCl is an excellent, inexpensive accelerator; its bad rap stems from its contribution to corrosion of steel reinforcement and metallic floor hardeners.

CN102167672A

The applicability of chloridizing roasting for removal of copper from the sulphide copper smelting waste slag of the "Karabashmed'" copper-smelting plant is investigated. Calcium chloride CaCl2 was used as chlorination agent. It is established that the chlorinating roasting of the initial slag presented by fayalite 2FeO∙SiO2, hasn't led to noticeable removal of copper.

Microwave

Ammonium chloride precipitates and is removed by filtration, and the solution is recycled to produce more sodium carbonate. Hou's process eliminates the production of calcium chloride. The byproduct ammonium chloride can be refined, used as a fertilizer and may have greater commercial value than CaCl 2, thus reducing the extent of waste beds.

Method of producing calcium carbonate from waste and by ...

Calcium chloride is produced industrially by at least three methods. In one process, hydrochloric acid is added to calcium carbonate, producing calcium chloride and carbonic acid: CaCO. 3 + 2HCl Æ CaCl2 + H2CO3. This is a synthetic process (Krohn et al., 1987). Potentially, this method can produce material of highest purity, and this is the

Lead recovery and waste disposal process

Oct 15, 2014· Accelerated carbonation of alkaline wastes such as steelmaking slag offers the potential to combine waste valorisation with climate change mitigation by utilising carbon dioxide (CO 2).One method of achieving this is through an indirect carbonation process to produce a marketable precipitated calcium carbonate (PCC), using ammonium salts to selectively extract calcium from steelmaking slag.

We have developed the Slag2PCC process, which binds carbon dioxide to calcium that has been dissolved from steel slag using ammonium chloride (NH4Cl). This produces precipitated calcium carbonate (PCC). We therefore reduce the amount of slag and bind carbon dioxide, thus combining two bad things to make one useful one.
