Dolomitic Quicklime is a high-performance industrial material composed primarily of Calcium Oxide (CaO) and Magnesium Oxide (MgO), produced by the high-temperature calcination of dolomitic limestone (CaCO₃·MgCO₃). Compared to standard quicklime and Enhanced Hydrate, Dolomitic Quicklime offers enhanced thermal stability, improved slag conditioning, and broader pH control capabilities—making it a preferred choice in steel manufacturing, flue gas desulfurization (FGD), soil stabilization, and environmental remediation.
At Jintai, we manufacture and supply premium-grade Dolomitic Quicklime tailored for high-efficiency industrial use, ensuring consistent quality, particle size control, and optimal reactivity.

Q1: What is the difference between Dolomitic Quicklime and High-Calcium Quicklime?
A: Dolomitic Quicklime contains both CaO and MgO, offering enhanced thermal stability and slag resistance, while High-Calcium Quicklime is nearly pure CaO with higher reactivity but less MgO buffering.
Q2: Is Dolomitic Quicklime suitable for drinking water treatment?
A: It is primarily used in industrial water treatment. For potable water, food- or pharma-grade quicklime should be used, depending on local regulations.
Q3: How should Dolomitic Quicklime be stored?
A: Store in dry, ventilated silos or bags, away from moisture to prevent slaking. Use PPE when handling due to high alkalinity.
Q4: Can Jintai provide custom particle sizes?
A: Yes. Jintai offers tailored sizing from 0–3 mm, 0–10 mm, or even fines, depending on your application and equipment needs.
Q5: What documents do you provide with each shipment?
A: Every shipment includes COA, MSDS, technical data sheets, and export documentation. REACH/ISO/FDA certificates available upon request.
