Mining & Flotation Reagents

Xanthate Price and Supply: What Drives the Cost Xanthate collectors – SIBX, SIPX, PAX, SEX – are consumed by the tonne in flotation plants, so their price matters as much as their performance. This page explains what drives the cost of xanthates and how to buy them well, without quoting prices (which move with the

SIBX and Xanthate Supply to African Mines Africa is one of the world’s great sulphide-flotation regions – the Central African Copperbelt, the West African gold belts, southern African PGM and base-metal operations – and xanthate collectors are consumed in huge volumes across the continent. This page covers how we supply SIBX and other xanthates to

SIBX in Copper, Gold and Base-Metal Flotation Sodium isobutyl xanthate (SIBX, CAS 25306-75-6) is one of the most widely used sulphide collectors. Its C4 chain gives a strong collecting power with reasonable selectivity, which is why it appears in copper, lead-zinc, nickel and gold circuits around the world. This page covers where SIBX is used,

MBT in Mineral Flotation 2-Mercaptobenzothiazole (MBT, CAS 149-30-4) is not only a rubber accelerator – it is also a well-established flotation collector. Its thiol group adsorbs on sulphide surfaces, and it is used where xanthates alone struggle, especially in the flotation of oxidised and partly oxidised ores. This article covers where MBT is used as

Xanthate Collector Selection Chart: SEX vs SIPX vs SIBX vs PAX Choosing a xanthate collector comes down to two variables: the chain length (which sets the balance between collecting power and selectivity) and the ore and target mineral. This page pulls that into one selection chart you can use to shortlist a collector before lab

Sodium Ethyl Xanthate (SEX, CAS 140-90-9): Properties, Uses and Selection Sodium ethyl xanthate (SEX) is the shortest-chain of the common xanthate collectors – the most selective, and the weakest. It is used where a clean, well-differentiated concentrate matters more than raw recovery, and where the ore’s sulphides float easily. This article covers what SEX is,

Potassium Amyl Xanthate (PAX, CAS 2720-73-2): Properties, Uses and Selection Potassium amyl xanthate (PAX) is the longest-chain of the common xanthate collectors, and the strongest. Where recovery matters more than selectivity, PAX is often the collector of choice for sulphide ores. This article covers what PAX is, how it compares with SIBX and SIPX, when

Sulfamic Acid in Mining and Mineral Processing Sulfamic acid (H3NSO3, CAS 5329-14-6) is a solid, easy-to-handle acid that mineral-processing and metal-production plants use for cleaning and descaling – jobs where a liquid mineral acid such as hydrochloric acid would be harder to transport, store and control. This article looks at where it is used in

Mining Reagents: Flotation Collectors, Depressants and Gold-Plant Chemicals Mineral processing uses a suite of reagents, each with a specific job in the circuit. This page is the overview of the mining reagents we supply – flotation collectors, depressants, frothers and modifiers, plus the chemicals used in gold leaching and cyanide destruction and in tailings dewatering.
