加压浸出富集铂族金属加压浸出富集铂族金属concentration of platinum group metal by pressure leachingJ一ayaJ一nehu fujl bozuJ一nshu加压浸出富集铂族金属(eooeentration ofplatinum group metal by pressure leaehing) 在高于大气压力下,用空气或纯氧浸出含贵金属物料的铜、镍、铁、硫,使贵金属残留在浸出渣而成为贵金属精矿的过程,为重要的铂族金属富集方法之一。加压浸出富集铂族金属是在氧化条件下于密闭的耐压、耐腐蚀的压煮器中实现的。浸出时通人压缩空气或纯氧,使氧分压达到0.3一IMPa,并加温至393一453K。在此条件下可加快贱金属的浸出,并使常压下难以浸出的贱金属硫化物或氧化物转变为可溶性硫酸盐。20世纪70年代以来,加压浸出广泛用于处理含铂族金属铜镍共生硫化矿冶炼的中间产物,如高镍梳,高镍铣磨浮产出的铜镍合金,镍、铜电解阳极泥等。加压浸出按所用介质分为加压硫酸浸出、自变介质性质氧压浸出和氨浸出三类。氨浸出时铂族金属溶解损失较大,不宜用于处理含铂族金属的物料。另外,盐酸对设备腐蚀严重,一般不用作浸出介质。加压硫酸浸出在硫酸介质中加压浸出含贵金属物料时,贵金属富集在浸出渣中,贱金属及其硫化物转变为可溶性硫酸盐。南非英帕拉(I mPala)铂矿公司三段加压浸出含贵金属0.15%的高镍毓,马太一吕斯腾堡(Matthey Rustenbury)铂矿公司加压浸出高镍铣磨细磁选出的含贵金属约1.5%的铜镍合金,前苏联加压浸出含贵金属约2.5%的粗镍电解阳极泥,均采用硫酸介质。加jia高镍锐加压浸出高镍梳含Ni49%、Cu29%、导出氢气,防止氢爆。520%一22%、铂族金属和金共1250一15509八。镶阳极泥加压浸出所处理阳极泥成分(质量分一0.o4mm粒级占60%~90%的高镍梳用含Cu 18一数。/%)为:Ni17.8,Cu25.6,Fe7.l,51.5,Pto.71,229/L、Ni 25~279/L、HZsO;50一1009/L的铜电解pdl.54。其中贱金属组分主要呈金属、氧化物、铁酸母液浆化,泵入四格室卧式机械搅拌压煮器内进行一盐状态。用含硫酸0.smol/L溶液按液固比(8一10):段浸出。矿浆在408一418K温度和空气压力约1浆化,加入压煮器后升温至393K,通入氧气使氧分。.SMPa下连续流动浸出3h。浸出时主要依靠Cu叶的压达到IMPa,机械搅拌浸出lh,铜浸出率达99%,镍氧化作用使高镍硫中的Ni3SZ、CuZS、NIS转化为63%,原料中的NIO和铁酸盐难于浸出完全。浸出渣NisO;和euso今。浸出液含Niloo一1209/L、Cu<109/中的贵金属富集3一4倍。L、FeZg/L。贵金属残留在浸出渣中。浸出渣中残留的自变介质性质氧压浸出在酸性介质中浸出贱金NIS、CuS用硫酸溶液进行第二段浸出,硫酸用量按S属硫化物时常析出元素硫,它氧化成硫酸根的速度很:(Ni+Cu+Co)一1.2(摩尔比)计算,最终浸出液慢;且熔融硫(硫熔点385.75K)常包裹其他物料,影含铜759/L。第二段浸出在408K温度和140kPa氧分响贱金属的浸出。当物料中元素硫含量较高时,先用氢压下进行4h。两段浸出合计浸出率(%)为:Ni99.9,氧化钠溶液或水浆化物料,或在矿浆中加入可消耗硫Cu98,co99,Fe93。贵金属在浸出渣中的回收率在99环酸的中和剂如氢氧化镍、碳酸镍、海绵铜等。矿浆加入以上。当贵金属精矿达不到所要求的品位(>45%)时,压煮器后升温、通入氧气,使浸出过程的介质性质靠化可进行第三段强化浸出。第三段浸出条件是:温度423学反应从碱性过渡为中性,最后变为酸性,将硫和呈硫一453K,浸出液含残余硫酸0.5一1.omol/L,氧分压化物和金属状态的贱金属组分逐步氧化为可溶性硫酸0.5一IMPa。也可根据第二段浸出渣的成分通过实验盐,而贵金属则富集在浸出渣中。
