目前，從陽極泥中富集碲主要有兩種方法：堿浸法和蘇打造渣法。選擇什么方法取決于陽極泥中碲的含量，不可一概而論。當(dāng)陽極泥中含碲在2%以上時(shí)，為了提高碲的回收率，避免在陽極泥處理過程中分散于各種礦物中，一般選擇堿浸法；當(dāng)含量小于2%時(shí)，一般選擇蘇打造渣法，采用在分銀爐氧化精煉的后期加入蘇打，使碲富集于蘇打渣中進(jìn)行回收。堿浸法堿浸富集碲的方法是將陽極泥先經(jīng)硫酸化、焙烤拖硒、水浸脫銅后用10%的苛性鈉浸出碲。水浸脫銅時(shí)，硫酸銅溶解進(jìn)入溶液，碲水解為二氧化碲留在渣中。此方法的優(yōu)點(diǎn)是，相對無腐蝕性，無揮發(fā)性硒損失，不需要清洗或氣體洗滌工序，并可大量的分離出硒和碲。但此方法耗氧量大，因?yàn)檠醪坏脑谖晚诘难趸^程，而且還耗于陽極泥中的其他組分，苛性鈉的耗量很大，不但把陽極泥中的硫酸鉛轉(zhuǎn)化為4價(jià)鉛酸，同時(shí)還把陽極泥中的二氧化硅轉(zhuǎn)化成硅酸鈉。而且在反應(yīng)過程中，陽極泥幾乎全部金屬硫酸鹽都轉(zhuǎn)化成硫酸鈉及各相應(yīng)的氧化物，氫氧化物和鈉鹽。雖然加壓堿浸法已經(jīng)有了很多研究，但是由于多種原因，至今還無一家工廠采用此法。工藝流程見圖：蘇打造渣法此法流程復(fù)雜，成本過高。氯化法提硒碲用鹵化冶金法從含硒、碲陽極泥中回收硒和碲的過程。</p><p> 發(fā)現(xiàn)人：繆勒發(fā)現(xiàn)年代：1782年發(fā)現(xiàn)過程：1782年，德國的繆勒，從一種呈白而略帶藍(lán)的金礦里提出白色金屬樣物質(zhì)，即碲。元素描述：有結(jié)晶形和無定形兩種同素異形體。電離能。結(jié)晶碲具有銀白色的金屬外觀，密度，熔點(diǎn)452℃，沸點(diǎn)1390℃，硬度是（莫氏硬度）。不溶于同它不發(fā)生反應(yīng)的所有溶劑，在室溫時(shí)它的分子量至今還不清楚。無定形碲（褐色），密度，熔點(diǎn)±℃，沸點(diǎn)±℃。碲在空氣中燃燒帶有藍(lán)色火焰，生成二氧化碲；可與鹵素反應(yīng)，但不與硫、硒反應(yīng)。溶于硫酸、硝酸、氫氧化鉀和反應(yīng)鉀溶液。易傳熱和導(dǎo)電。元素來源：從電解銅的陽極泥和煉鋅的煙塵等中回收制取。元素用途：主要用來添加到鋼材中以增加延性，電鍍液中的光亮劑、石油裂化的催化劑、玻璃著色材料，以及添加到鉛中增加它的強(qiáng)度和耐蝕性。碲和它的化合物又是一種半導(dǎo)體材料。元素輔助資料：碲與它的同族元素硫相比，在地殼中的含量少得多。碲成單質(zhì)存在的礦是極難找到的。碲在一般狀況下有兩種同素異形體，一種是晶體的碲，具有金屬光澤，銀白色，性脆，是與銻相似的；另一種是無定形粉末狀，呈暗灰色。碲在自然界有一種同金在一起的合金。1782年奧地利首都維也納一家礦場監(jiān)督牟勒從這種礦石中提取出碲。首要技能條件（一）球磨與浸出。</p><div
