Mining & Flotation Reagents

O,O-Dimethyl phosphorodithioate is one of the standard building blocks of organophosphate chemistry, and it earns that position because it delivers two things at once: a sulphur nucleophile and a phosphorus centre, in a molecule small enough to react cleanly. This page covers how it is used as an intermediate, what the specification has to guarantee,

Dithiophosphate collectors – the class known generically as aerofloats – sit alongside xanthates as the two workhorses of sulphide flotation, but they are chosen for a different job. Xanthates are strong and cheap; dithiophosphates are weaker per molecule and considerably more selective. Knowing which one a circuit needs, and which alkyl chain length within the

O,O-Dimethyl phosphorodithioate is a small molecule with two distinct careers. In one it is a reactive intermediate: a sulphur nucleophile that carries a phosphorus centre, used to build organophosphate actives. In the other it is the acid half of a dithiophosphate collector, the flotation reagent class known generically as an aerofloat. Understanding which career a

How to Buy Mining Reagents: A Buyer’s Guide Buying flotation reagents is not like buying a commodity salt: you are buying activity that degrades over time, in packaging that must keep moisture out, delivered to a plant that cannot stop. This guide pulls the purchasing essentials together – what to specify, what to protect, and

Flotation Reagents: Selection Guide A flotation circuit is a system of reagents, each with a job: collectors make target minerals float, frothers stabilise the froth, depressants hold unwanted minerals back, activators switch a mineral on, and pH modifiers set the chemistry. This page is the selection guide – what each class does, when to use

How to Buy SEX: Specs, Activity and Packing Sodium ethyl xanthate (SEX, CAS 140-90-9) is the cheapest xanthate and the most selective. Buying it well means confirming activity, protecting it from moisture, and using it where its selectivity – not its price – earns its place. This guide covers what to check. 1. The specification

SEX in Selective Flotation: Where the Shortest Xanthate Wins Sodium ethyl xanthate (SEX, CAS 140-90-9) is the shortest-chain common xanthate – the most selective and the weakest. That trade-off is exactly what makes it valuable: SEX is the collector you reach for when the problem is separating sulphides cleanly, not maximising recovery. This page covers

How to Buy PAX: Specs, Activity and Packing Potassium amyl xanthate (PAX, CAS 2720-73-2) is the strongest common xanthate – and the most expensive of the simple xanthates, because amyl alcohol costs more than ethanol or isopropanol. That makes buying it well a question of activity, dose and fresh stock. This guide covers what to

PAX in Gold and Copper Flotation Potassium amyl xanthate (PAX, CAS 2720-73-2) is the longest-chain common xanthate and the strongest collector. Where the priority is maximising recovery of sulphide minerals – gold-bearing sulphides, copper rougher circuits – PAX is often the collector of choice. This page covers how PAX is used and how it fits

How to Buy SIPX: Specs, Activity and Packing Sodium isopropyl xanthate (SIPX, CAS 140-93-2) is a selective sulphide collector, and – like every xanthate – it is bought on activity, protected from moisture, and consumed before it degrades. This guide covers what to confirm on a SIPX enquiry. 1. The specification to confirm Property What
