Enquire NowTypes of Quick Lime
1. High-Calcium Lime: This type consists of more than 90% calcium oxide (CaO). It is the most common form used in various industrial applications due to its high reactivity and purity.
2. Dolomitic Lime: This lime contains both calcium oxide (CaO) and magnesium oxide (MgO), typically in the ratio of 40% MgO and 60% CaO. It is used in applications requiring both compounds, such as in steelmaking.
3. Hydrated Lime (Slaked Lime): While technically not quick lime, hydrated lime (Ca(OH)2) is produced by reacting quick lime with water. It has a specific range of applications, especially in water treatment and construction.
Manufacturing Process of Quick Lime
The production of quick lime involves a high-temperature process known as calcination, where limestone (calcium carbonate, CaCO₃) is heated to produce calcium oxide (CaO) and carbon dioxide (CO₂). Quick lime manufacturers play a crucial role in optimizing this process to ensure high purity and efficiency, catering to the demands of industries such as construction, steel, and chemical processing. Here’s an in-depth look at the process:
Our production process for Quick Lime involves several meticulous steps to ensure the highest quality product:
- Extraction of Limestone: High-quality limestone is mined or quarried from deposits. The purity and size of the limestone directly affect the quality of the resulting quick lime.
- Crushing and Screening: The extracted limestone is crushed and screened to achieve uniform particle size, ensuring even calcination during the heating process.
-
Calcination in Kilns:
The heart of the process lies in the calcination step, where the crushed limestone is heated to high temperatures (approximately 900°C to 1000°C) in specially designed kilns. Different types of kilns can be used for calcination, including:
- Rotary Kilns: Cylindrical kilns that rotate continuously, ensuring even heat distribution.
- Shaft Kilns: Vertical kilns ideal for high-purity limestone, providing efficient heat utilization.
- Fluidized Bed Kilns: Advanced kilns that ensure rapid heating and uniform calcination.
During calcination, the high heat causes the limestone to decompose into quick lime and carbon dioxide gas: CaCO3 → heat → CaO + CO2 This reaction is endothermic, requiring a consistent supply of heat. Modern kilns often use fuels like coal, natural gas, or biomass to maintain the required temperature.
- Storage: The processed quick lime is then packed in moisture-proof bags or stored in silos. Proper packaging is critical to prevent the quick lime from reacting with atmospheric moisture or carbon dioxide, which can reduce its effectiveness.
- Transportation: Finally, the packaged quick lime is transported to end users. HTMC Group ensures secure logistics to maintain the quality of the product during transit. This entire process is carefully monitored to deliver high-purity quick lime that meets the specific requirements of various industries. At HTMC Group, we combine state-of-the-art technology and stringent quality control to produce quick lime that stands out in terms of reliability and performance.

Sugar Refining:
In the sugar industry, quick lime is used to clarify and purify sugarcane or sugar beet juice.
- Juice Clarification: It reacts with impurities, forming insoluble compounds that can be filtered out, ensuring the production of high-grade sugar.
- Mining and Drilling: Quick lime has crucial applications in mining and drilling operations.
- Food and Beverage Industry: Although its use is limited, quick lime has niche applications in food processing.
- Corn Nixtamalization: Quick lime is used to process corn kernels, enhancing their nutritional value and texture for making tortillas and other products.
- pH Control: It is sometimes used in food and beverage formulations to regulate pH levels.
Leather Tanning
Quick lime is utilized in the preparation of animal hides during the leather tanning process.
- Dehairing Agent: It helps loosen and remove hair from hides, facilitating the production of soft and durable leather.
- pH Control in Mineral Processing: Quick lime stabilizes the pH during flotation processes, enhancing the efficiency of metal extraction.
- Heap Leaching: In gold and copper mining, quick lime is used to optimize leaching conditions for metal recovery.
- Drilling Fluids: It acts as a pH modifier in drilling fluids, maintaining stability during operations.
Waste Management
Quick lime is employed in the treatment and stabilization of waste.
- Stabilizing Hazardous Waste: It is used to solidify and neutralize industrial and municipal waste, ensuring safe disposal.

Safe Handling and Storage
Quick lime should be stored in a clean, dry, and well-ventilated area, completely away from moisture, since exposure to water triggers an exothermic reaction that generates significant heat and can pose a safety hazard if the material is stored carelessly. Bags and containers should remain sealed until use. Given its strongly alkaline and reactive nature, protective equipment including a dust mask, gloves, and safety goggles is essential when handling the product to avoid skin or eye contact and inhalation of fine particles. Storage in a dry environment below 30°C helps preserve reactivity and prevents premature slaking during storage.

Frequently Asked Questions
Quick lime, also known as calcium oxide (CaO), is a highly reactive alkaline compound produced by heating limestone at high temperatures in a kiln. It is widely used across steel, cement, water treatment, and chemical industries for its reactivity and ability to alter the chemistry of the materials it's combined with.
The chemical formula for calcium oxide is CaO, representing one calcium atom bonded to one oxygen atom. It is produced by the thermal decomposition of calcium carbonate (limestone) during calcination.
Calcium oxide is also commonly known as quick lime, burnt lime, or unslaked lime. These names all refer to the same compound before it reacts with water to form hydrated lime.
When calcium oxide reacts with water, it undergoes an exothermic reaction called slaking, producing calcium hydroxide (hydrated lime) and releasing a significant amount of heat. This reaction should always be handled carefully, since the heat generated can be intense in concentrated quantities.
Quick lime lumps are the coarse, unprocessed pieces of calcium oxide that come directly out of the kiln after calcination. Burnt lime powder refers to the same material after it has been crushed and milled into a fine, free-flowing powder, offering faster reactivity and easier dosing for applications like water treatment and chemical processing.
Yes, HTMC Group manufactures and supplies quick lime in both lump and powdered form, with customizable lump sizes and mesh specifications depending on the buyer's application and equipment requirements.
