Calcium inorganic salts 

Lime provides calcium input required to manufacture stable, high‑quality inorganic salts. Its purity and reactivity directly impact product performance and process reliability. 

• Calcium chloridefor deicing, water treatment, brewing, and food processing 
• Calcium nitratefor fertilizer formulations 
• Calcium fluoride for metallurgy, glass, ceramics, and fluorinated chemical synthesis 
• Calcium phosphatefor fertilizers, animal feed, nutrition, baking, and pharmaceuticals 
• Calcium sulfate for construction materials, agriculture and food additives 
• Calcium silicate for construction materials, insulation, anti‑caking and desiccation 
• Calcium carbide for acetylene production and steelmaking 
• Calcium hypochlorite for water disinfection, sanitization and odor control 

Calcium organic salts 

Many organic calcium salts rely on our lime’s consistent purity and reactivity to meet food‑grade, pharma‑grade, and industrial-grade specifications. The lime quality often determines many other properties of the final products. 

• Calcium citrate for dietary supplements, acidity regulation and pharmaceutical excipients 
• Calcium acetate for preservation and pH regulation 
• Calcium lactate for stabilization, thickening and food applications 
• Calcium stearate as lubricant, stabilizer and anti‑caking agent in plastics, foods, and cosmetics 
• Calcium propionate for food preservation, animal feed and personal care 
• Calcium formate for feed additives and preservatives; and performance enhancement in concrete and mortars 

Organic chemistry applications 

Lime functions as a critical processing aid in organic synthesis, supporting neutralization, pH control and purification in applications such as: 

• Propylene oxide production for polyurethanes, polyethers, surfactants and solvents 
• Epichlorohydrin for epoxy resins 
• Polyvinylidene chloride (PVDC) for specialty packaging 
• Polyhydric alcohols for coatings, adhesives and paints 
• Organic acids such as citric and lactic 
• Sugar and gelatin processing for food applications 

Inorganic chemistry applications 

Lime ensures reliable neutralization, purification, and impurity control in key inorganic processes, including: 

• Titanium dioxide production for impurity removal to meet pigment brightness specifications 
• Chlor-alkali production (NaOH, HCl): brine purification and pH control 
• High‑alumina cement production: forming high‑performance mineral phases 
• Hydrofluoric acid: purification and contaminant precipitation 
• Hydrometallurgy: pH adjustment and impurity removal for efficient metal recovery 

Fertilizers 

Calcium‑based compounds contribute to nutrient efficiency, soil conditioning and fertilizer stability: 

• Calcium nitrate as a key nitrogen and calcium source in NPK 
• Calcium ammonium nitrate (CAN) stabilized with limestone ordolomite fillers 
• Calcium phosphate as a phosphorus source for root and crop development 
• Calcium polysulfide and thiosulfate for soil conditioning and nutrient uptake 

Plastics and polymers 

Calcium‑based products support major polymer production routes and formulation performance: 

• Quicklime enables Propylene oxide (PO) production for polyurethane precursors 
• Calcium hydroxide supports epichlorohydrin (ECH) production for resin intermediates 
• Fillers improve mechanical and thermal properties in plastics 

Sugar industry 

Calcium‑based products ensure clean, efficient and stable sugar processing: 

• Juice purificationin beet and cane processing 
• Removal of organic and inorganic contaminants 
• Dehardening of the juice and stabilization of process conditions 

Biofuels 

Lime plays a critical role in the conversion of biomass for second‑generation bioethanol production by: 

• Facilitating lignocellulosic biomass breakdown 
• Improving enzymatic performance  during hydrolysis 
• Enabling more efficient glucose release and fermentation 

Petrochemicals, oil and gas  

Calcium‑based additives contribute to operational protection and performance, in lubricant and oil additives: improved lubrication quality, acid neutralization, and corrosion protection. 

Chemical plants depend on high volumes of process water and often operate on-site energy systems. We support these environmental needs with: 

• Lime for pH control and water remineralization 
• Efficient treatment of acidic wastewater prior to recycling or discharge 
• High-performance lime for flue gas cleaning in on‑site power and steam generation 

We help you maintain compliance without compromising process performance.
