底吹炉炼铜熔炼白烟尘的脱铜脱砷研究

Study on the Removal of Copper and Arsenic from White Dust of Copper Smelting in Bottom Blown Furnace

以北方铜业垣曲冶炼厂底吹炉熔炼工序的白烟尘为研究对象,对硫酸氧化浸出过程以及浸出液中和沉淀砷铁的过程进行了研究分析,以达到铜砷分离,烟灰开路的目的。

In this paper,the white dust from the bottom blown furnace smelting process in Yuanqu smelter of Northern Copper industry is taken as the research object,and the process of sulfuric acid oxidation leaching and leaching solution neutralization and precipitation of arsenic and iron are studied and analyzed,so as to achieve the purpose of copper and arsenic separation and soot open circuit.
