在从斑岩铜矿中浮选铜矿物的体系中 ,应用 3因素、3水平、面心立方体 (FCC)试验设计法研究了重要化学变量对近年来新开发的N 烯丙基 O 烷基硫代氨基甲酸酯 (ATC)性能的影响 ,研究的化学变量包括捕收剂烃链长度、捕收剂浓度、起泡剂种类。本研究的目的是利用试验设计的优点 ,评价多变量的影响和相互作用 ,填补ATC捕收剂目前缺乏的基础应用理论的空白。试验测定了这些工艺变量对铜回收率、精矿铜品位、铁回收率、浮选精矿的粒度的影响 ,据此确定了最佳工艺条件。将ATC捕收剂的浮选效率与两种熟知的捕收剂 (O 烷基 N 乙氧羰基硫代氨基甲酸酯 (ECTC)和N 烷基 N 乙氧羰基硫脲 (ECTU) )浮选效率进行了比较。
In the system of flotation of copper minerals from porphyry copper deposits, a three-factor, three-level, face-centered cubic (FCC) experimental design was used to study the effect of important chemical variables on the recent development of N-allyl O-alkyl The effects of thiocarbamate (ATC) performance on the chemical variables studied include collector hydrocarbon chain length, collector concentration, and type of foamer. The purpose of this study was to take advantage of the experimental design to evaluate multivariate effects and interactions and to fill gaps in the basic theory of applications currently lacking for ATC collectors. The effects of these process variables on copper recovery, concentrate grade, iron recovery, and particle size of flotation concentrates were tested. The optimum process conditions were determined. The flotation efficiency of the ATC collector was compared to two well-known collectors (O-alkyl N-ethoxycarbonylthiocarbamate (ECTC) and N-alkyl N-ethoxycarbonylthiourea (ECTU) Efficiency is compared.
