Bauxite
Premium Ore. Essential Aluminium Source
Didwaniya Group exports superior-grade bauxite ore, rich in alumina content and sourced from trusted mining locations. Known for its consistent quality and ideal physical properties, our bauxite meets the stringent requirements of aluminium producers worldwide seeking dependable raw material for smelting and refining.
Bauxite is the primary ore of aluminium, composed mainly of hydrated aluminium oxides and hydroxides. It forms through the weathering of aluminium-rich rocks in tropical and subtropical climates and is characterized by its earthy texture and a range of colors from white to reddish-brown, depending on iron oxide content. The ore undergoes careful mining and beneficiation to enhance its alumina concentration, making it the fundamental raw material for producing aluminium metal and related products.
The largest producers of bauxite include countries such as Australia, Guinea, Brazil, and India, with India contributing significantly to the global supply. The quality and alumina content of bauxite are critical factors determining its industrial applications, and Didwaniya Group ensures sourcing from mines with superior geochemical profiles, thereby offering premium ore to clients in the metals and minerals industry.
Characteristics

Application
Bauxite serves as the cornerstone for aluminium production, used extensively in the extraction and refining processes to obtain alumina, which is then electrolyzed to produce aluminium metal. Beyond aluminium manufacturing, bauxite is also used in the production of refractory materials, abrasives, cement, and chemicals. Its versatile industrial applications make it indispensable across sectors such as automotive, aerospace, packaging, construction, and electronics.
Storage Condition
Store bauxite ore in dry, covered, and well-ventilated storage areas protected from moisture and contamination. Maintain relative humidity below 70% and avoid exposure to direct rain or water to preserve ore quality and prevent degradation.
