✅ SEX (Sodium Ethyl Xanthate) 

SEX (Sodium Ethyl Xanthate) is a widely used flotation collector known for its strong selectivity and moderate collecting strength, making it ideal for the flotation of copper, lead, and certain zinc ores.
Compared to other xanthates, SEX offers superior selectivity with less activation of pyrite and unwanted gangue minerals, resulting in cleaner concentrates and improved grade control.

SEX is especially effective in flotation circuits requiring controlled recovery, including polymetallic ores, low-sulfide ores, and ores where excessive froth or unintended sulfide activation must be avoided. Its balanced performance makes it suitable for both rougher and cleaner flotation stages.

Engineered for selective metallurgical performance, SEX provides:
• Moderate collecting strength with high selectivity
• Cleaner concentrates with reduced pyrite flotation
• Effective performance in balanced and low-grade sulfide ores
• Fast adsorption on chalcopyrite, galena, and associated sulfides
• Improved grade control vs stronger xanthates like SBX or PAX
• Stable operation across typical flotation pH ranges
• Cost-effectiveness in selective flotation circuits

SEX is commonly applied in:
• copper flotation (chalcopyrite)
• lead flotation (galena)
• zinc flotation after activation (in selective circuits)
• low-pyrite or complex polymetallic ores
• operations requiring cleaner froth and high selectivity
