一种特殊的高铜低铁铜精矿冶炼工艺探讨

一种含铜高达64%，含铁仅2.2%的特殊铜精矿，通过分析其成分及物相，表明主要矿物为辉铜矿。针对这种特殊的高铜低铁铜精矿，提出了几种工艺可行的冶炼方案，包括闪速炉一步直接炼铜、侧吹熔炼+多枪顶吹连续吹炼火法工艺和焙烧+浸出+电积的湿法工艺，并从外部建设条件、技术经济指标等方面对火法工艺方案和湿法工艺方案进行对比及评价，对冶炼工艺的选择给出了建议。

Discussion on the Smelting Process of a Special High Copper and Low Iron Copper Concentrate

There is a special copper concentrate which contenting up to 64% copper and only 2.2% iron. The analysis of its composition and phase indicates that its main mineral is chalcocite. For this special copper concentrate with high copper and low iron, several feasible smelting schemes are proposed, including the flash furnace direct-to-blister copper smelting and side-blow smelting + top-blow converting, hydrometallurgy and roasting + leaching + electrowinning. And by comparing and evaluating of pyrometallurgy with hydrometallurgy from the aspects of external construction conditions, technology and economy, suggestions are given for the process selection.
