碱浸-硫化沉淀法提铊
extraction of thallium by alkaline leach-sulfide precipitation

一压团、Na0H熔炼即得金属蛇。 此法适于从高砷的含金属佗及硫化蛇的物料中提取佗,在硫化沉淀佗的单元过程中,既沉淀出铭,又同时除去砷,并能综合回收含佗物料中的锢、福及锌等,是从高砷含佗的铜福渣中回收蛇的一种较好方法。um by alkaline leaeh一sulfide preeiPi-tation)含蛇物料经过或化焙烧、碱浸出、硫化沉淀处理,进而生产金属枕的过程。含蛇物料有部分蛇以佗硫化物形态存在,需通过氧化焙烧使之转变为易挥发的T12O进入挥发烟尘中得以回收。利用T12O易溶于碱溶液的性质,用碱浸出含铭挥发物,使铭转入溶液。再用NaZS使溶液中的T120转变成T12S沉淀析出。进而从T12S沉淀物中制取金属佗。 本法适用于处理含铭0.01%~。.26%的铅、锌、铜熔炼烟尘以及含铭2写~18%的铜福渣。这两种含蛇物料的主要杂质是铅、锌和硫等。前苏联用这种方法从含蛇炼铅烟尘或铜福渣中回收花,其工艺流程如图。中国也曾用这种方法回收铭,后段作业改为TI:S硫酸浸出,得T12SO;用Nso3萃取,其反萃液仍接前苏联工艺的氯化沉淀佗、硫酸转化、置换和碱熔获得纯度”.99%的金属蛇。 含佗物料在773一923K温度下进行氧化焙烧,物料中佗便转变成T120挥发进入烟气,从烟气得含蛇。.4%一1%的挥发物。含T120挥发物用NaOH的混合溶液进行碱浸出,碱浸出温度控制在353~363K,终点pH控制在8~10。在此浸出条件下,T12O转变为T12eO3和TI(OH)进入碱浸出液: TI:O+NaZCO3+H:O—T12CO3+ ZNaOH T12O+HZO—ZTI(OH)获得含蛇0.6~0.659/L的碱浸出液。在保持碱浸出液温度不变条件下,加入物料重量5%的NaZS,此时碱浸出液中的T12CO:和Tl(OH)便生成T12S沉淀析出: T12CO3+NaZS—T12S十+NaZCO3 ZTI(OH)+NaZS—T12S令+ZNaOH约有90%的佗生成T12S沉淀析出。如T12S沉淀物含砷过高,则需多添加Na多,使砷以多硫化物形态转入溶液而除去: AsZS3+3NaZS一ZNa3AsS3此时可得含蛇约78%的沉淀物,残留砷降到0.1%一0.2%。T12S沉淀物用锌电解(见锌电解沉积)废液浸出2~3h,浸出液固比为20:1,浸出温度控制在363K,约有97%的蛇转入溶液。从处理氧化亚佗挥发物到转入锌电解废液的浸出液中的蛇回收率为75%一80%。含佗的浸出液用锌粉置换得海绵铭,海绵蛇经遗竺竺竺粤生盛望竺竺1 .1__ 宗…一矛 广二杏,__}竺军巡竿份件计门坠…竺一沤知综合回收锢、锅卫属兰竺}t 中…一查处理甲放竺竿竺一当巡}l Tr~,eeL,}}里二奥 竺竺色遭~浏卜分一习{ 碱浸一硫化沉能法提佗流程J lanJ旧一Iiuhua ehendianfa tita碱漫一硫化沉淀法提蛇(extraetion of thalli-
