Description
Calciumhydroxide, inorganic compounds, chemical Ca (OH) 2. commonly known as cooked lime or lime. It is a white powder -like solid. After adding water, it appears two layers of upper and lower layers. The upper water solution is called clarifying lime water.
It is a kind of strong alkali, has the ability to sterilize and anticorrosive, and has corrosion effect on the skin and fabrics. However, because its solubility is not large, the degree of harm is not as large as strong alkali such as sodium hydroxide. Calcium hydroxide is widely used in industry. It is a commonly used building material and is also used as a bactericide and chemical raw materials.
Application
Hydrated lime is a highly basic substance. Therefore, it is used in various processes that require the regulation of PH in acidic environments. In the mining industry, it works s a PH regulator during the extraction of gold.
In mining, hydrated lime used to stabilize the cyanide complex and prevent hydrogen cyanide from occurring. It also acts as a PH regulator in the slurry to make conditions conducive for the floatation of various minerals. Further in the mineral production process, it is added into leaching tanks as this is another point where hydrogen cyanide is likely to form.
When being applied as a neutralizing agent, the PH of the material to be neutralized is first determined. Then a proportionate amount of hydrated lime is added until the desired PH is attained. The same happens in the in the leaching pads where the return feed water determines how much lime would be used in the process. If the ore seems too difficult to cyanide leach, sodium cyanide and lime is added at the ball mill to increase the times that lime will be in contact with the ore. The result is a more balanced PH and prevention of the formation of the cyanide gas.
Hydrated lime is used to modify PH in froth floatation processes to increase the efficiency of the process. In addition, it is used to correct the PH of water in treatment plants. In many detergent manufacturing plants, sulfuric acid is used and some of it ends in the effluent water. Hydrated lime is introduced to neutralize this acidity.
