Sodium Ethyl Xanthate (SEX), identified by CAS number 140-90-9, is a chemical compound that plays a significant role in industrial applications, most notably in mineral processing. As a key flotation reagent, understanding its scientific properties is crucial for optimizing its use and for procurement professionals making sourcing decisions. This article details the physical and chemical characteristics of SEX and its diverse applications, emphasizing the benefits of sourcing from reputable manufacturers.

The physical appearance of Sodium Ethyl Xanthate is typically described as a white acicular crystal, though it can also appear as a yellowish powder or pellet with a pungent odor. This crystalline structure and solubility in water are key to its effectiveness in aqueous-based flotation systems. Its molecular formula, C3H5NaOS2, indicates the presence of sodium, sulfur, and carbon atoms arranged in a specific structure that allows for its characteristic chemical behavior.

Chemically, Sodium Ethyl Xanthate functions primarily as a collector in froth flotation. Its efficacy stems from its ability to form insoluble compounds with metallic ions, particularly those found in sulfide minerals. For instance, it can react with ions of copper, cobalt, and nickel, creating hydrophobic coatings on these mineral surfaces. This hydrophobic property is what enables the mineral particles to attach to air bubbles during flotation, leading to their separation and concentration. This makes it an indispensable reagent for copper flotation and the recovery of other valuable metals.

The applications of SEX are extensive, primarily within the mining industry. It is widely used in the preferential flotation of fine flotability or complex sulfide minerals. Its strong collecting ability makes it suitable for minerals that are otherwise difficult to float. Beyond direct flotation, SEX also finds use as a precipitant in hydrometallurgical processes and as a sulfidation promoter in rubber manufacturing. When considering the purchase of this versatile chemical, sourcing from a reliable manufacturer in China can offer significant advantages in terms of cost and consistent quality. The sodium ethyl xanthate price per ton can vary, but high-purity product from established suppliers provides better long-term value.

For industries requiring this chemical, understanding its CAS number (140-90-9) is essential for precise identification and sourcing. Whether you are seeking to enhance your mineral recovery operations or looking for a stable supply of chemical intermediates, exploring options from Chinese manufacturers is a practical approach. Procurement managers should always inquire about specifications, safety data sheets (SDS), and packaging details when planning to buy sodium ethyl xanthate 140-90-9 to ensure the best fit for their operational needs.
