Recently, a letter from our customer shows that:

    We have carbon and pyrite as penalties in our copper. Also Insoles are a big challenge. Any reagent that can help reduce pyrite and carbon n our final copper is welcome.

After analyzing the actual situation, we provided him with foaming agent and d421 for testing. In order to solve the problem that the properties of ore change greatly, the corresponding test methods are given, and the collectors, pyrite inhibitors and carbon inhibitors are also provided.
