Gypsum Manufacturing Facility
Cement and Agricultural Growth with Advanced Production
Kemcore operates its first manufacturing plant located in Ndola, Zambia,
with an annual capacity of 100,000 metric tons of synthetic gypsum.
What is synthetic gypsum?
Synthetic Gypsum is a mineral composed of calcium sulphate dihydrate. At Kemcore, we produce gypsum through a process where limestone reacts with sulphuric acid. This synthetic gypsum is used in cement production, plaster, ceiling boards, and chalk. Additionally, gypsum plays an important role in agriculture as a soil fertiliser, improving soil structure and providing essential nutrients like calcium and sulphur to crops.
Economic Impact
The facility has created approximately 100 jobs, contributing to local employment. By sourcing gypsum locally, we support both the cement and agricultural industries. This helps stabilise cement prices and ensures affordable infrastructure and food security in the country.
Supply Chain & Resources
The plant sources all raw materials locally, near Ndola, Zambia, reflecting our commitment to supporting local economies. We prioritise the reduction of CO2 emissions in our operations to promote environmental sustainability.
Our Products & Market
Gypsum cement grade
Today the plant produces high-quality gypsum for cement manufacturers, essential in controlling cement’s setting time during production.
The Role of Gypsum
Gypsum is added during the grinding process to regulate hardening, ensuring sufficient time for proper handling and placement.
Key Benefits
- Enhances workability and durability
- Ensures consistent quality for construction applications
Our gypsum is trusted for delivering reliable performance in cement manufacturing.
Agricultural gypsum
Kemcore Agri-Gypsum is produced to improve soil structure and fertility. It supplies essential calcium and sulphur, crucial for crop growth, and is particularly effective in sulphur-deficient soils. Often used in conjunction with other fertilisers, it is also OMRI-approved for organic agriculture.
Kemcore supports food security in Zambia amid climate change and helps local communities adopt modern practices to increase yields. To facilitate this, Kemcore is registered under the E-Voucher Farmer Input Support Program of the Government of Zambia.
6 benefits of Agri-Gypsum
· Soil Health
· Water Conservation
· Soil Structure Improvement
· Sodic soil Remediation
· Crack Reduction
· Compaction Reduction
Kindly note that if you have saline soil issue, the application of gypsum is different and required soil test.
Calcitic Lime
Calcitic Lime, is a high-purity limestone product primarily composed of calcium carbonate (CaCO₃). This product is essential for improving soil health, enhancing crop yields, and providing various industrial applications. The limestone is mined and pulverised in Ndola.
Applications
Agriculture: Neutralises acidic soils, enhancing nutrient availability and crop yield. Provides essential calcium, promoting robust plant growth and development.
Construction: Key component in the production of cement and concrete.
Industrial: Used in manufacturing processes such as paper, glass, and more.
Key Benefits
- Balanced Nutrient Supply: Provides both calcium and essential nutrients for optimal plant growth.
- Enhanced Soil Quality: Improves soil structure, aeration, and water retention, promoting healthier crops.
- Versatile Applications: Suitable for various industries, making it a valuable addition to your supply chain.

Dolomitic Lime
Dolomitic Lime, also known as Dolomitic Agro-lime, is a naturally occurring mineral composed primarily of calcium magnesium carbonate (CaMg(CO₃)₂). It is widely used in agriculture and various industrial applications due to its dual benefits of calcium and magnesium. The limestone is mined and pulverised in Ndola.
Applications
Agriculture: Amends soil pH and provides essential magnesium for crops. Improves nutrient availability and enhances soil structure.
Construction: Utilised in the production of cement and concrete.
Environmental: Employed in water treatment and flue gas desulphurisation processes.
Steel Manufacturing: Acts as a flux in steel production, enhancing quality and efficiency.
Key Benefits
• Balanced Nutrient Supply: Provides both calcium and magnesium, essential for optimal plant growth.
• Enhanced Soil Quality: Improves soil structure, aeration, and water retention, promoting healthier crops.
• Versatile Applications: Suitable for various industries, making it a valuable addition to your supply chain.
