What is Potassium Butyl Xanthate?

Potassium butyl xanthate (PBX) is a water-soluble yellowish or pale grey powder. Potassium butyl xanthate solubility in ethanol is higher than in water. It is a xanthate derivative made by mixing carbon disulfide (CS2) and butanol when an alkali, like potassium hydroxide, is present (KOH). PBX is a powerful collector employed in the flotation of nonferrous metallic sulfide ores like copper, lead, and zinc. The alcohol chain connected to the xanthate molecule determines the strength of the collector, with butyl being a moderate-strength collector.

PBX has a molecular weight of 188.4 g/mol and the chemical formula C5H9KOS2. This formula shows potassium butyl xanthate structure correctly. The substance has a boiling point of roughly 260°C and a melting point of 163-164°C. Because it burns quickly, PBX needs to be handled carefully. It smells distinctively like a gas called carbon disulfide, which is poisonous and highly flammable. The shelf life of PBX is up to one year when kept in a cold, dry environment.


PBX has uses in various other sectors in addition to its employment in the flotation of metallic sulfide ores. For instance, it functions as a vulcanization accelerator in the rubber sector. To make metal ions in solution precipitate as solids, PBX is also utilized in the metallurgical industry as a precipitant. The possibility of using PBX as a selective scavenger to remove mercury from wastewater has also been researched. Studies show that PBX can efficiently remove up to 99% of the mercury ions in synthetic wastewater solutions. In general, the substance is an adaptable and practical chemical compound with applications in a variety of industries.

Potassium Butyl Xanthate and Potassium N-Butyl Xanthate

Butyl xanthate comes in two forms: potassium butyl xanthate and potassium n-butyl xanthate. The butyl group’s position on the xanthate molecule is the only distinction between them. The butyl group is joined to the xanthate molecule by its regular carbon chain in potassium n-butyl xanthate, whereas in potassium butyl xanthate, the butyl group is joined to the xanthate molecule by an isobutyl group. Different physical and chemical qualities emerge from their distinct structural differences. Potassium n-butyl xanthate is a liquid at room temperature with a strong odor and a boiling point of 210-220°C. In both water and ethanol, it dissolves and condenses to form a transparent solution. In contrast, potassium butyl xanthate is a crystalline solid with a melting point of 163-164°C. It is also soluble in water and ethanol but forms a turbid solution in water due to its lower solubility.

Potassium Butyl Xanthate Production Process

Potassium Butyl xanthate preparation is critical in establishing the end product’s quality and properties. This useful collector reagent is produced using a multi-step procedure to guarantee that the final result meets the criteria and requirements for its intended usage. In general, butanol and carbon disulfide must be combined with an alkali to generate potassium O-butyl dithiocarbonate, which must then be filtered, dried, and subjected to quality control checks to verify the product fulfills specifications. However, the specifics of the manufacturing procedure may change depending on the grade of PBX being manufactured. Any variation from the established technique might have an impact on the product’s quality and efficacy because the production process determines the final product’s qualities, such as solubility and purity. Thus, it is essential to implement quality control procedures to guarantee that the final product is of the requisite quality and meets the standards of the mining sector.

It is vital to note that the manufacturing process is critical in generating several classes of PBX, including superior, pure, technical, and custom, which are used in specific mining applications. In the following, three crucial steps of PBX production are explained.

The First Step

In the initial Iran potassium butyl xanthate synthesis process, carbon disulfide (CS2) and butanol are combined with an alkali, usually potassium hydroxide (KOH). This process is essential for creating the potassium O-butyl dithiocarbonate intermediate chemical required to manufacture PBX. In polar solvents like butanol, carbon disulfide dissolves easily despite being a chemical molecule that is very poisonous and explosive. The potassium salt of O-butyl dithiocarbonate is created when carbon disulfide and butanol are combined in the presence of KOH. When butanol and this intermediate chemical interact, the result is PBX. The reactants must be adequately mixed under regulated conditions to produce PBX with the correct quality and yield.

The Second Step

Following the creation of potassium O-butyl dithiocarbonate, the combination proceeds through the filtering and drying process, the third phase of the PBX production process. This phase is essential for eliminating any contaminants that might have been created during the previous production stages. The PBX product is filtered to separate the solid particles from the liquid to create a more concentrated solution. The filtrate is subsequently dried to remove any remaining moisture, producing an impurity-free, yellowish, or light grey powder. Drying is often done in a controlled setting to prevent the product from being exposed to any pollutants that could degrade its quality. Then, quality control procedures are used to confirm the PBX product’s quality further and make sure it adheres to the standards and requirements for the usage for which it is intended.

The Third Stage

Quality control, the last stage of the PBX production process, is essential to ensuring that the final product satisfies the requirements for its intended purpose. The product is put through several quality control procedures, including consistency, stability, and purity tests. The product is also examined for contaminants, such as carbon disulfide or lingering moisture. To make sure that the PBX product fulfills the necessary quality requirements, the results of these tests are compared to the benchmarks established by potassium butyl xanthate manufacturers or regulatory bodies. To ensure the quality of the product, any deviations from the criteria are noted and rectified. The quality control process is critical in PBX production because it guarantees that the final product is safe and effective for usage in a variety of industries, including mining.
