Mining & Flotation Reagents

Sodium Metabisulfite in Gold Mining and Flotation Sodium metabisulfite (Na2S2O5, CAS 7681-57-4) is a workhorse reagent in mineral processing. In gold plants it destroys the cyanide left after leaching; in flotation circuits it depresses unwanted sulphide minerals and controls pulp chemistry. This article explains where it is used, how much is typically needed, and what

Glycine — the simplest amino acid, better known as a food and pharmaceutical ingredient — has become one of the most talked-about reagents in gold mining. Glycine leaching offers a low-toxicity alternative to cyanidation, and it is gaining traction in Africa, Mongolia, Australia and beyond for treating difficult ores. This article explains how glycine works

Xanthates are effective flotation collectors, but they carry a specific set of hazards that every buyer, warehouse manager and plant operator must respect: decomposition to carbon disulfide (CS2), combustible dust, and moisture sensitivity. This guide covers the safety, storage and handling of xanthates such as sodium isopropyl xanthate (SIPX, CAS 140-93-2) — the practical rules

Ethyl xanthate (SEX) and isopropyl xanthate (SIPX) are the two most common short-chain xanthate collectors in sulfide flotation. They look similar — both are pale yellow sodium xanthates — but the one-carbon difference in their alkyl chains changes collecting strength, selectivity and cost. This article compares SEX and SIPX so mill operators can choose the

Sodium isopropyl xanthate (SIPX, CAS 140-93-2) is the most widely used flotation collector for copper, lead and zinc sulfide ores. But “widely used” does not mean “used the same way everywhere” — the dose, the circuit position and the combination with other reagents change with ore type, mineralogy and water chemistry. This article covers practical

Sodium isopropyl xanthate (SIPX, CAS 140-93-2) is the workhorse flotation collector of the sulfide mining industry — a cost-effective, versatile xanthate used across copper, lead and zinc circuits worldwide. This article covers the manufacturing chemistry of SIPX, the specifications that define its quality, its role in flotation, and the safety considerations that govern its handling.

In mining, water is both a processing medium and a cost. The slurry leaving a flotation or grinding circuit must be thickened, the water recycled, and the tailings stacked or stored safely — and anionic polyacrylamide (PAM, CAS 9003-05-8) is the reagent that makes it all possible. This article explains how PAM is used in

SIBX (sodium isobutyl xanthate, CAS 25306-75-6) is an effective and widely used flotation collector, but like all xanthates it requires careful handling. This guide summarizes the key safety, storage and regulatory points that buyers, warehouse staff and plant operators should know. Always refer to the supplier’s Safety Data Sheet (SDS/MSDS) for the specific product batch.

Buying flotation reagents is not like buying commodity chemicals. The specification sheet, the quality consistency and the supplier’s documentation all directly affect your flotation performance — and your recovery rate is money. This guide walks through everything a procurement or mill manager should check when buying SIBX (sodium isobutyl xanthate, CAS 25306-75-6). 1. Understanding the
