Description

Technical Field

[0001] The present application relates to the technical field of preparation of mineral processing reagents, and in particular to a preparation device of a pyrite inhibitor. Background Art

[0002] For the lead-sulfur mixed flotation concentrate with high reagent residue, due to the weak alkali process used in the mixed flotation stage, it is inevitable that there are a large number of heavy metal ions in the pulp. In this case, pyrite is easily activated by copper and lead ions, causing it to adsorb a large amount of collectors, reducing the selective flotation effect of pyrite.

[0003] In the existing flotation process, by selecting appropriate inhibitors, the activation reaction of pyrite to copper and lead ions can be effectively inhibited, preventing it from adsorbing collectors and ensuring the flotation effect. Most of the existing inhibitors with good use effects are mixed reagents, which require the use of different reagents in a mixed combination. Therefore, by confirming and determining the best matching ratio, the problem of pyrite being activated by copper and lead ions and adsorbing a large amount of collectors can be effectively inhibited, thereby improving the selective flotation effect.

[0004] For inhibitors with confirmed matching components and proportions, they need to be mixed in corresponding proportions under different temperature environments. Currently, inhibitors are made by mixing four different reagents in specific proportions, and each step of the production is manually operated. This manual operation is easily affected by the operator's technical level and subjective factors, resulting in insufficient consistency and stability in the inhibitor production process. At the same time, manual operation is usually time-consuming and has low production efficiency. Utility Model Content
