Potassium Isoamyl Xanthate Mineral Flotation Collector Chemical Raw Material

Potassium Isoamyl Xanthate (CAS:928‑70‑1, molecular formula is a high‑purity xanthate‑series flotation reagent synthesized by reaction of isoamyl alcohol, carbon disulfide and potassium hydroxide, followed by crystallization and refining treatment. It appears as pale yellow to off‑white granular crystal or powder with irritating sulfur‑containing odor, soluble in water and polar solvents, easily decomposed under acidic and humid conditions. Compared with lower‑carbon alkyl xanthate, isoamyl xanthate owns stronger collecting performance and better selectivity for sulfide ore. Thanks to its outstanding ore‑collecting capability and fast adsorption performance on mineral surface, it has become a key flotation collector widely used in mineral‑processing industry, complying with industrial flotation reagent specifications. Our production adopts low‑temperature synthetic crystallization technology to strictly control free alkali, residual alcohol and impurity indicators, stable effective content, widely applied across non‑ferrous metal ore flotation, metallurgical mineral processing, waste‑water treatment and fine chemical synthesis fields。

Applications
Mineral Processing & Non‑Ferrous Metallurgy Industry (Core Consumption Field): It is high‑efficiency collector for sulfide ore flotation. Widely used for flotation separation of copper ore, lead ore, zinc ore, pyrite and other polymetallic sulfide ores. It can form stable hydrophobic adsorption layer on mineral surface to improve mineral hydrophobicity and realize effective separation of target ore from gangue minerals. It exhibits excellent collecting capacity for refractory complex ores, improving concentrate grade and metal recovery rate. It is also used for gold‑silver associated sulfide ore flotation operation.
Waste‑Water Treatment Industry: Applied as heavy‑metal ion precipitant for industrial heavy‑metal‑containing wastewater. It can react with copper, lead, zinc, cadmium and other heavy‑metal ions to generate insoluble sulfide‑complex precipitates, facilitating solid‑liquid separation for heavy‑metal removal from wastewater.
Metallurgical & Ore‑beneficiation Auxiliary Agent: Used in bulk flotation and selective separation process of mixed sulfide ore; can be compounded with frother and modifier to optimize flotation index. Suitable for roughing and scavenging operations of various non‑ferrous metal mines.
Fine Chemical and Other Fields: Important intermediate for organic synthesis; also used as vulcanization accelerator and chemical analytical reagent in partial special chemical processes

Product Advantages
✅ High‑carbon‑chain xanthate structure brings strong collecting power and good selectivity, suitable for complex refractory sulfide ore resources, effectively improving metal recovery rate compared with short‑chain xanthate products.
