This 96.5% pure Sodium Metabisulfite (Na2S2O5) is a granular flotation reagent designed for mineral processing, particularly in sulfide ore flotation circuits. It acts as a sulfite reducing agent and depressant, enhancing the separation of copper, lead, zinc, and other base metals from gangue minerals. The reagent is supplied in 25 kg bags or 1000 kg big bags for bulk export, meeting standard industrial-grade specifications.
Sodium Metabisulfite is widely used in froth flotation due to its ability to modify pH and redox conditions, improving selectivity for target minerals. The granular form ensures even dissolution in flotation pulps, while the 96.5% purity minimizes impurities that could interfere with downstream processing. Typical applications include copper-molybdenum separation, lead-zinc differential flotation, and pyrite depression in gold recovery circuits.
Mining operations and chemical processors source this reagent for its cost-effectiveness and reliability in large-scale flotation plants. The product is classified under HS codes for sodium metabisulfite, with bulk shipments requiring proper handling to prevent moisture absorption and degradation. Buyers should confirm packaging, storage recommendations, and shelf life with the supplier to ensure product integrity upon delivery.

Before ordering, verify the reagent’s purity and moisture content, as these directly impact flotation performance. Request a certificate of analysis (COA) and material safety data sheet (MSDS) to confirm compliance with your operational and safety requirements. Check if the supplier can provide lot-specific data for traceability in large-scale operations.
Confirm packaging, shipping method, and Incoterms, as Sodium Metabisulfite is hygroscopic and requires protection from moisture during transit. Big bags (1000 kg) are cost-effective for bulk orders but may need specialized handling equipment. Lead times can vary based on production and shipping schedules, so request a delivery timeline to your facility or port.
Upon receipt, inspect the packaging for damage and test a sample for solubility and pH to ensure it meets the stated specifications. Store the reagent in a dry, sealed environment to prevent degradation. Establish a rotation system to use older stock first, as the reagent’s effectiveness can diminish over time, especially in humid climates.
