Product Brief
Mineral Processing Reagent EF1309
This reagent can effectively inhibit pyrite under low alkalinity condition, which can solve the problems of pipeline clogging and flotation water of too high pH value brought about by massive use of lime, etc. It can be widely used in flotation of copper-sulfur separation and zinc-sulfur separation, and in flotation of other nonferrous metals. The goal of mineral inhibition is achieved by improving the surface hydrophilicity of target minerals and reducing the adsorption of collectors.
Application Fields：Prepared into an aqueous solution and added into the ore slurry.

Advantages & Features
- Mainly used as an effective inhibitor for processing nonferrous metal iron sulfide and bismuth sulfide. It has a good inhibitory effect on pyrite, bismuth sulfide and other minerals under low alkalinity.
Working Principle
Improving the surface hydrophilicity of target minerals, reducing the collector adsorption, whereby achieving the purpose of selective mineral inhibiting.
The Application Achievements
This reagent was first tested and applied in the zinc-sulfur separation process of a copper-lead-zinc process plant in Qinghai, it can effectively improve the zinc-sulfur separation efficiency; it was also used in the molybdenum bismuth separation process of a polymetallic mine in Hunan as an early-stage exploratory application, which proved that this reagent can replace sodium sulfide to inhibit bismuthinite effectively.
