Frequently Asked Questions

What is SEX (Sodium Ethyl Xanthate) used for? SEX is used as a collector reagent in froth flotation to recover sulphide minerals such as gold-bearing pyrite, copper sulphides, lead, and zinc ores.

How is SEX different from other xanthates like SIPX? As a shorter-chain xanthate, SEX offers faster collector action and stronger flotation kinetics, making it well suited to circuits where rapid mineral recovery is prioritized, compared to longer-chain collectors such as SIPX.

Can Nwans Chemicals supply bulk quantities of SEX? Yes. As a dependable SEX supplier South Africa mining operations trust, Nwans Chemicals supplies SEX in bulk for mining operations, processing plants, and export customers.

Is technical support available for reagent dosing? Yes. Nwans Chemicals provides technical guidance to help optimize SEX dosage and flotation reagent schemes for specific ore types.
