Description

Ferrous sulfate monohydrate (CAS 13463-43-9 ) is an iron salt used across water treatment, agriculture, and metallurgical processing as a coagulant, pH modifier, and iron source. Feromax and Fespan are recognized commercial forms of this compound found in feed and supplement supply chains. In municipal and industrial water treatment, it acts as a coagulant and flocculant. The compound is utilized to remove phosphates and suspended solids and is used to reduce chromate in effluent streams. Agricultural applications include soil amendment to correct iron deficiency in crops. It is also used for pH correction in alkaline soils, where it is incorporated into fertilizer blends or applied directly. In animal feed production, it supplies bioavailable iron to prevent anemia. This essential mineral helps livestock and poultry meet nutritional fortification targets. Mining operations use it in hydrometallurgical processes, including the precipitation of metals from process liquors. It is further utilized for pH control in acid mine drainage treatment. Ferrous sulfate monohydrate is supplied as a granular or powdered solid to meet various industrial requirements. Standard grades include technical, feed-grade, and agricultural-grade. Feed and nutritional applications typically requiring compliance with USP or BP specifications for safety. Bulk supply is common in 25 kg bags or bulk tote quantities for industrial buyers. This ensures efficient handling and storage for large-scale manufacturing and processing facilities. Contact us for supply of Ferrous sulfate monohydrate Request Quote
