Minerals Portfolio
Kaolin
Refined Purity, Engineered Performance
Our kaolin is a premium, refined aluminosilicate designed for high brightness, purity, and performance consistency. It offers excellent opacity, smoothness, and rheological control, making it ideal for ceramics, paints, paper, rubber, and specialty applications. Processed with advanced beneficiation techniques, our kaolin ensures uniform quality tailored to industrial requirements.
Ball Clay
Strength in Form, Precision in Performance
Our ball clay is a high-plasticity, fine-grained material engineered to deliver excellent workability and green strength. It enhances forming properties and ensures superior surface finish across ceramic applications such as tiles, sanitaryware, and tableware.
Feldspar
Driving Vitrification, Enhancing Strength
Our feldspar acts as a key fluxing agent, enabling efficient vitrification and reducing firing temperatures in ceramic bodies and glazes. With optimized alkali content and low impurity levels, it enhances strength, translucency, and surface finish. Our feldspar is processed to meet strict quality standards, ensuring consistency and performance across ceramic and glass industries.
