In the intricate world of mineral processing, flotation stands as a cornerstone technique for separating valuable minerals from their host rock. At the heart of this process are flotation collectors, chemical reagents that selectively alter the surface properties of minerals. Among the most vital and widely used collectors for sulfide minerals is Sodium Butyl Xanthate (SBX). For mineral processing engineers, R&D scientists, and procurement specialists, understanding the function and sourcing of effective collectors like SBX is essential for optimizing recovery rates. As a leading manufacturer and supplier of industrial chemicals from China, we are dedicated to providing insights into the critical role of SBX.

Sodium Butyl Xanthate functions by adsorbing onto the surface of target sulfide minerals, such as copper, lead, and zinc sulfides, as well as pyrite. This adsorption creates a hydrophobic layer on the mineral particles. When air bubbles are introduced into the flotation cell, these hydrophobic particles adhere to the bubbles and rise to the surface, forming a mineral-rich froth that can be easily collected. The specificity and strength of this adsorption are key to the collector’s effectiveness. SBX, with its characteristic C5H9NaOS2 molecular formula and CAS number 141-33-3, is prized for its strong collecting power, making it particularly effective for copper ores and in complex multimetallic ore flotation.

The selection of a collector often depends on the specific mineralogy of the ore, the pH of the pulp, and the presence of other reagents. SBX is known for its good selectivity and its ability to function effectively over a range of pH conditions, although its decomposition in strongly acidic environments must be considered. Its application is widespread in the bulk flotation of various non-ferrous metallic sulfide minerals. For industries looking to buy Sodium Butyl Xanthate, partnering with a reputable manufacturer and supplier is crucial. Chinese manufacturers are at the forefront of producing high-quality SBX, often available in 90% and 85% grades, ensuring consistent performance and cost-effectiveness.
