TBP Mining Extraction Reagent Selective Metal Separation Stable
5115 Depressant is an advanced mineral processing reagent specifically developed for selective separation of chalcopyrite and pyrite. Presented as a black liquid with remarkable chemical stability, it possesses a solid content of no less than 40.0% and offers superior inhibition performance even under challenging slurry conditions.
As a crucial modifier in flotation operations, it is widely used in beneficiation of polymetallic ores—such as copper-molybdenum and molybdenum-sulfur ores—containing chalcopyrite and pyrite. It plays a key role in enhancing molybdenum concentrate quality by effectively suppressing impurity minerals and improving the enrichment of valuable metals.

Key Features
Highly selective suppression: Shows selective suppression toward chalcopyrite and pyrite. Its polar groups form stable adsorption films with copper/iron ions on mineral surfaces, preventing collector attachment and reducing floatability of unwanted minerals. During molybdenum flotation, it efficiently inhibits copper and sulfur impurities, decreasing copper content in the final concentrate.
Consistent performance: Delivers consistent inhibition in neutral to weakly alkaline pulp systems with minimal impact from temperature fluctuations. Suitable for both roughing and cleaning stages in high copper-sulfur molybdenum ores, it helps reduce cleaning cycles and simplifies the separation process.
Excellent dispersibility: Boosts excellent dispersibility, allowing rapid and even distribution in slurry. It is highly compatible with common collectors and frothers without adversely affecting the recovery of target minerals. In ores with high clay content, it optimizes reagent usage by adjusting slurry viscosity and improving overall efficiency.
Advantages
Provides powerful and selective inhibition of chalcopyrite and pyrite, significantly raising molybdenum concentrate grade and resolving challenges in processing high-impurity ores.
Adaptable across a broad spectrum of neutral to weakly alkaline conditions, ensuring operational flexibility and ease of management. It retains stable performance under varying process parameters, offering high efficiency and cost-effectiveness in production environments.
