This paper studies the effects of PH value,carbon chain length and structure of xanthate on the flotation behaviors of cerusite.
考察了白铅矿硫化的pH范围,黄药碳链长度及其结构对黄药捕收白铅矿浮选行为的影响。
It is necessary to sulfide cerusite when the collector is xanthate and the best range of pH for sulfuration is 8～10.
用黄药作为白铅矿捕收剂时,需要对白铅矿进行硫化,硫化的最佳pH范围是8~10;碳链越长,对白铅矿的捕收效果越好;异构体黄药捕收能力较正构体要好;在不硫化的条件下,黄药能够浮选白铅矿,但浮选指标不高。
The influences of the dosage of Na2S, pH values,sulfidization time and the types of pH modifiers on the flotation of cerusite and limonite have been studied in this paper,and the performance of ethyl xanthate,butyl xanthate,isobutyl xanthate,amyl xanthate and isoamyl xanthate are studied in detail respectively.
详细研究了硫化钠用量、矿浆pH值、硫化时间以及pH调整剂种类对白铅矿和褐铁矿浮选的影响,重点考察了乙基黄药、丁基黄药、异丁基黄药、戊基黄药和异戊基黄药五种黄药的捕收性能。
