Frequently Asked Questions

What is sodium sulfide used for in mining?

As a sulfidizing agent, it reactivates oxidized copper, lead, and zinc mineral surfaces ahead of xanthate flotation.

Does sodium sulfide have uses outside mining?

Yes — leather tanning, pulp and paper processing, and heavy-metal precipitation in wastewater treatment.

When should sulfidizer be dosed in a flotation circuit?

Ahead of the collector addition point, giving it time to condition the pulp before flotation begins.
