Quicklime

3. Industrial aluminum: Lime helps remove silica from bauxite ore while producing alumina. Used in the production of chemicals such as calcium carbide, propylene oxide, sodium carbonate and glycerine, lime is also a reactant in the production of calcium compounds and is used to adjust pH when needed.
4. Construction industry: Lime is used in the production of silicon lime bricks, insulators and construction materials. Lime is also used in brick mortar and making walls. In addition, lime is also added to concrete and mortar to improve construction performance.
5. Food industry: lime reacts with raw sugar water for the production of both radish and sugar cane. Lime is an ingredient in baking soda and helps keep fruits and vegetables fresh.
6. Industrial wastewater treatment: Lime neutralize acids that create waste in industry, thus preventing corrosion and protecting the natural environment. Lime also removes silicon, manganese, fluoride, iron and other other impurities in the water.
In wastewater treatment plants (including industrial and urban wastewater). Lime is widely used in adjusting the pH in wastewater which contain acid to agglomerate heavy metals and phosphates.
          Lime is commonly used in the treatment of industrial residues, dredged waste from sewers, urban waste treatment before being reused in agriculture or burned into ash.
Lime helps to make waste become coagulated easier in transportation, preventing fermentation, deodorizing and eliminating pathogens. Lime also adds calcium and magnesium, both of which are beneficial when the waste is reused in agriculture.
In addition, lime is also used to treat soils contaminated with hydrogen carbon
            In Liquid Waste:

•  Lime is used to treat liquid waste, which eliminates dirty colloids, increases the size of dirty impurities and increases the dry matter content in it. This helps the filtration easier and improves the durability of the water separator.
• Normally, lime is applied where the use of pressure filtration equipment. However, the use of lime makes it possible to clean pathogens by increasing the pH of the waste, preventing fermentation, so that the stink are also eliminated.

7. Exploiting industrial metals: Lime is also used to exploit metals such as copper, mercury, zinc, nickel, gold, lead and silver.
8. Production of paper:
        Manufacturers use lime to restore caustic soda during the conversion of wood chips to pulp. Lime pulp bleaching also dissolves non-cellulose component from straw and decomposes it while producing strawboard and kneading dough.
In the paper industry, lime is often used to regenerate caustic soda from excess sodium carbonate from the pulp manufacturing process. Lime can be used to create additives to increase whiteness, improve the surface as well as reduce transparency. In paper factories, lime is the substance used to soften water 
9. Pollution control: lime and limestone are used to absorb sulfur dioxide from flue gas in smelters and power plants.Lime is used in the emissions treatment process, significantly reducing air pollution levels.
Increasing demand for electricity leads to increased burning of fossil fuels. These fuels contain a lot of sulfur and release them directly into the atmosphere, which is the main cause of acid rain, mass destruction of trees, depleted ponds and destruction the environment.
10. Waste water treatment: Lime reduces pollution by removing organic matter, phosphates and nitrogen from the wastewater. It prevents vegetation on streams and lakes, controls stink from waste ponds and precipitates heavy metals.
Lime plays an important role in wastewater treatment, low cost and high efficiency. Quicklime or hydrated lime can clean acid water, waste from other industrial processing. In addition, lime also removes stink. Lime is ensure to remove a lot of dangerous substances from organic waste, remove heavy metals, pathogens, bacteria and stink.
- Increasing pH in wastewater causing heavy metals to precipitate in the form of hydroxide.
- Precipitation of phosphates and sulphates in wastewater as well as heavy metals in insoluble salts such as Ca3(PO4)2, CaSO4 that are easily obtained
- Neutralizing the colloids in water and concentrating impurities, roling as agglomerates whereby metal salts or similar substances are supplemented.
11. Nonferrous metals industry:
- Lime is often used in the selection of sulfide ores to help obtain metal on demand. This application is deployed in the industries that exploit lead, gold, nickel, zinc and copper.
- Lime has the ability to increase and control the pH in cyanide reducing solutions in gold and silver. Due to the ability to adjust the pH, lime plays a role in maintaining the cyanide solution in liquid state, avoiding the formation of gas cyanide and escaping to the environment.
- In the process of accumulation, crushed limestone with low sulfur content and alkalinity is used with powdered lime to sinter iron ore.
Lime is used as a flow to refine and remove steel, phosphorus and silicon impurities
