摘要:

铜和银都是河台金矿床中重要的伴生元素,银在铜精矿中与铜同步富集到50~6Og/t,通过对铜精矿中的银量作原子吸收光谱法测定试验,研究了铜对银在原子吸收光谱法测定中的干扰,并提出了消除干扰的方法。该分析方法;住确度与经典方法一致,有一定的实践指导意义.

关键词: 河台金矿, 铜精矿, 原子吸收光谱法, 银量, 干扰效应, 铜元素

Abstract:

Copper and silVer are the main coexist elenaents in Hetai gold naine. Silver in the copper concentrates mineral was enriched with copper to 50 —60g/t, within the enrichnaent of copper synchronously.W e measuresed silver content through AAS,analyzed the interference of  copper elenaent in the meantime,and developed a new method to elinainate the negatiVe effect of copper and get satisfactory results conapaI℃d with classica1 methods.

Key words: Hetai gold naine, Copper concentrates, AAS, Ag content, Interference, Copper elenaent
