 · The role of lime in the flotation process is most apparently the effect on the properties of the flotation foam. When the amount of lime is appropriate, the formed foam is relatively stable and has a suitable viscosity; when the amount is large, the foam is too stable, the foam is sticky, and even causes a "running" phenomenon, making the production process difficult to operate and control.

 · 3 Summary of the copper mineral flotation process (1) Copper minerals (such as chalcopyrite and covellite) that do not contain iron are similar in floatability. Cyanide and lime have weaker inhibition on them, so a large amount of lime can be added to inhibit pyrite in the separation of copper and sulfur without seriously affecting the floatability of copper minerals.
