Lime's multifaceted magic across industries.

Application of Lime

Steel Industry

Quicklime is essential in steelmaking, a vital industry for automotive, construction, and national economies. As a flux, it purifies steel and finds further use in metallurgy and refractories.

Chemical Industry

Lime is a cornerstone of the chemical industry. Its compounds form the basis for a wide range of products. Sigma's high-quality offerings, Pride and Pearl, have proven invaluable in the production of fine chemicals.

Paper Industry

Lime, in both its quicklime and hydrated lime forms, is a critical component in the pulp and paper industry. Its inclusion is essential for optimizing paper quality, particularly in enhancing the paper's opacity.

Flue Gas Industry

Hydrated Lime is crucial for cleaning up fuel-gas emissions from coal-fired power plants, incinerators, and industries. It purifies flue gases before release, safeguarding air quality and public health.

Agricultural Uses

Hydrated Lime is a versatile soil amendment. It raises soil pH, improving crop growth. It also enhances soil structure by preventing crusting. Additionally, lime is used in various agricultural practices, including composting and fertilizer management.

Water Treatment Plants

In wastewater treatment plants (both urban or industrial) Hydrated Lime and Quick Lime are widely used for correcting the pH balance. It neutralizes acids, removes metals and phosphates, and aids in sludge treatment. This versatile substance also helps clean up hydrocarbon-contaminated soils.

Road Building Industry

Lime is a crucial component in enhancing the stability of in-situ soils or aggregates employed in road construction. By incorporating hydrated lime, an impermeable base can be formed, effectively reducing the infiltration of rainwater.

Leather Industry

Lime has been a key ingredient in leather making for centuries. It removes hair and plumps hides, preparing them for tanning. This cleaning process results in clean leather.

Lubricant Industry

Hydrated Lime is used in plastic extrusion, petroleum refining, and lubricating grease manufacturing. It functions as a lubricant, improving efficiency and product quality in each application.

Glass Industry

Limestone and Quick lime are crucial fluxing agents in glassmaking. These materials lower melting points and enhance glass workability. When color accuracy is vital, they remain the preferred choice.

Sugar Industry

Hydrated lime and quicklime are essential in sugar production from sugarcane and sugar beets. They purify the sugar solution by eliminating impurities and regulating pH.

Paint & Pigment Industry

Precipitated calcium carbonate, a common pigment in paints, is produced from lime. This versatile compound also serves as a filler in cement paints and other applications.

Pharmaceuticals Industry

Lime constitutes a critical component in the production process of numerous calcium-based pharmaceuticals. Its properties are indispensable for the creation of a wide range of medications that rely on calcium for their therapeutic effects.

Construction Industry

Lime is one of the oldest building materials, alongside stone and mud. It's crucial in making mortar and plaster, binding them together. This process involves lime combining with air to form calcium carbonate, releasing water. Hydraulic lime hardens underwater, and Quick Lime Powder is key in producing AAC blocks.

Dairy Industry

Lime is used to neutralize cream acidity before pasteurization. In fermented skimmed milk, it forms calcium lactate, a compound with medicinal uses and a precursor to lactic acid.
