Sodium Antimonate Manufacturing Plant Project Report 2026: Cost Analysis, ROI, and Feasibility Insights

The process involves mixing crude antimony oxygen powder with hydrochloric acid to create an antimony trioxide solution, which is then subjected to chlorination. Sodium hydroxide is then added to the mixture to form sodium antimonate, followed by vacuum filtration, washing, drying, and grinding.

The main feedstocks are crude antimony oxide or antimony-containing material, hydrochloric acid, and sodium hydroxide, with oxidizing agents and water also used depending on the process route. As an indicative estimate, antimony-based feedstock may account for 55-70% of direct raw material costs, sodium hydroxide 15-25%, hydrochloric acid 8-15%, and other process materials 5-10%.

Manufacturing costs are mainly influenced by antimony feedstock prices and availability, energy consumption, chemical inputs, process efficiency, and maintenance requirements. Antimony prices can have a particularly strong impact because the metal and its compounds are the major feedstock base, while filtration, drying, grinding, waste treatment, and environmental controls add to operating costs.

Asia-Pacific, particularly China, dominates sodium antimonate manufacturing. China has a highly concentrated production base, with SMM's survey covering more than 99% of China's sodium antimonate capacity, while Chinese manufacturers also report substantial dedicated production capacities. An indicative capacity estimate is China 65-75%, other Asia-Pacific countries 10-15%, Europe 5-10%, North America 5-8%, and other regions 2-5%.

Manufacturing requires controls for antimony-containing dust, acidic and alkaline wastewater, process emissions, and hazardous residues. Facilities generally need effluent treatment, emission-control and dust-collection systems, along with safe handling and storage procedures. Sustainability measures can include recovery of antimony from process streams, wastewater recycling, reduction of material losses, efficient energy use, and proper management or recycling of antimony-containing residues.
