n.[礦]黃鉀鐵礬

The preparation of Ni-Zn ferrite from sodium jarosite residue was studied. 對(duì)黃鈉鐵礬渣制備復(fù)合鎳鋅鐵氧體進(jìn)行研究。

Obviously, jarosite process can successfully extract both zinc and indium. 可見，黃鉀鐵礬法工藝處理高銦鋅精礦可以達(dá)到綜合回收鋅和銦的日的。

The compositions of oxidation film which could restrain biooxidation of arsenopyrite were indicated as jarosite and arsenolite by XRD. 用X射線粉晶衍射法對(duì)細(xì)菌氧化產(chǎn)物進(jìn)行物相分析，結(jié)果表明氧化物的主要成分為黃鉀鐵礬，其次為砷華。

Most iron can be removed through jarosite process.The content of zinc sulfate can reach more than 98% by evaporating, cooling, crystallization and centrifuging. 用黃鐵礬法除去大部分鐵,通過蒸發(fā)、冷卻結(jié)晶、離心脫水,可最終使硫酸鋅的含量達(dá)98%25以上。

This paper covers production practice of jarosite process in hot-acid leaching and comparison between iron hydroxide process and jarosite process that are used for iron removal. 介紹了熱酸浸出黃鉀鐵礬工藝的生產(chǎn)實(shí)踐，對(duì)氫氧化鐵法和黃鉀鐵礬法兩種除鐵方法進(jìn)行了比較。
