本研究針對錫陽極泥粉末進行資源再生研究，採用濕法冶金技術，將錫陽極泥中錫、銻、鉍、銅、銀等金屬資源進行再生，研究流程主要分為特性分析、酸溶浸漬、分離純化、金屬產物析出等四部分，並使最終產物能回用到產業端。
第一部分為錫陽極泥粉末之特性分析，藉由組成元素分析、表面特性分析以及晶相分析等方法，得到錫陽極泥之基本化學特性後，做為後續資源化方法選擇之依據，並訂定整體實驗流程。
第二部分為酸溶浸漬，本研究利用鹽酸及過氧化氫，探討藥劑濃度、氧化劑添加量、液固比及溫度等參數後，使錫陽極泥中錫、銻、鉍、銅及銀之溶出率分別達到85.32%、96.93%、97.63%、99.81%、0.89%，並使用硝酸針對浸漬殘渣中的銀資源進行浸漬，溶出率達到99.80%。
第三部分為金屬分離純化，針對錫、銻、鉍、銅四種浸漬液中的離子進行分離。以磷酸三丁酯(Tributyl phosphate)作為溶媒萃取法之萃取劑，藉由探討環境鹽酸濃度、萃取劑濃度、油水比與震盪時間等參數，得到最佳萃取條件，將錫、銻離子萃取至油相，並使鉍、銅離子殘留在水相中，完成第一階段分離。接著藉由鹽酸與硝酸兩種反萃劑，分別將油相中的銻與錫反萃，完成銻、錫兩金屬之分離；留在水相中的鉍、銅離子則以選擇性化學沉澱法，藉由調整酸鹼值使鉍先行沉澱，形成氯氧化鉍固體，再經由過濾，與含有銅離子之溶液完成分離。
第四部份為金屬產物析出研究，將錫、銻、銅、銀離子透過添加氫氧化鈉與氯化鈉進行沉澱，得到錫、銻、銅之氫氧化物及氧化銀固體。接著以煅燒法與還原法得到氧化錫、氧化銻、氧化銅與金屬銀；氯氧化鉍則以氫氧化鈉進行反應後，得到氧化鉍。最終針對金屬產品進行化學分析後，純度皆為98%以上。

Tin anode slime is a by-product of tin electrolytic refining industry, and this study investigated a hydrometallurgical way to recover Sn, Sb, Bi, Cu, and Ag from tin anode slime. The study was divided into three parts: leaching, separation, and recovery. In the first part, Sn, Sb, Bi, and Cu were leached by hydrochloric acid, and Ag in the residue was leached by nitric acid. In the separation part, TBP was used as the extractant of solvent extraction. Sn and Sb were extracted into the organic phase and separated by different stripping agents. Bi and Cu ions remained in the aqueous phase were separated by the selective precipitation method. In the recovery part, with the chemical precipitation process and calcination, the final products are SnO2, Sb2O3, Bi2O3, CuO, and Ag, and all the purity are over 98%. The recovery rate of Sn, Sb, Bi, Cu, and Ag are 80.76%, 74.75%, 94.76%, 97.39%, and 98.1%.
