Sodium Ethyl Xanthate (SEX)
CAS Number: 140-90-9
Sodium Ethyl Xanthate (SEX) is one of the most widely used collectors in copper and base metal sulfide flotation. Its short ethyl carbon chain provides good selectivity against pyrite under controlled pH conditions, making it ideal for selective copper flotation circuits. SEX dissolves readily in water and is compatible with a broad range of pH modifiers and frothers.
