Abstract

Metode baru dalam me-recovery logam Tembaga (Cu) dari electronic waste (e-waste) adalah menggunakan bantuan listrik yang disebut electro-leaching. Metode tersebut merupakan metode alternatif pengganti metode leaching tradisional. Penelitian ini bertujuan untuk melarutkan tembaga dengan metode electro-leaching. Bahan yang digunakan dalam penelitian ini adalah Simcard dan garam (NaCl) sebagai elektrolit. Simcard mengandung logam tembaga dan beberapa logam berharga lainnya seperti perak (Ag), emas (Au) dan palladium (Pa). Proses electro-leaching dilakukan di dalam reaktor electrolytic cell dimana gas klorin akan dihasilkan dari proses elektrolisis selanjutnya gas klorin akan mengekstrak tembaga yang terdapat pada Simcard. Penelitian ini dilakukan dengan memvariasikan potensial elektroda (voltase)/arus listrik (ampere), konsentrasi garam dan waktu. Dari penelitian ini, simcard mengandung logam Tembaga (Cu) sebesar 40,53% dan dapat dipisahkan dengan metode elektro-leaching dalam reaktor acrylic berpengaduk dengan hasil terbaik pada kondisi operasi ; Suhu 30⁰ C, tekanan 1 atm, konsentrasi larutan garam 10%, beda potensial 10 Volt, waktu leaching 60 menit, dan kecepatan pengadukan 600 rpm menghasilkan yield campuran logam Simcard sebesar 98,59%. ====================================================================================================== New methods to dissolve the copper (Cu) of electronic waste (ewaste) is leaching with the help of electricity, called electroleaching. This is the alternative method to change the traditional leaching methods. The objective of this research is copper dissolving using electro-leaching method. Materials used in this study is Simcard with contain 40.53 % copper and salt (NaCl) as the electrolyte. Simcard metal containing copper and some other precious metals such as silver (Ag), gold (Au) and palladium (Pa). Electro-leaching process occurs in an electrolytic cell reactor where chlorine gas will be produced by electrolysis process and then chlorine gas generated will extract the copper in the Simcard. This research was conducted by various electrode potential (voltage)/electric current (ampere), salt concentration, and time. The operation condition was kept at pressure 1 atm, temperature 30oC, and the stirring speed of 600 rpm. The best result shows 98.59% simcard metal could be removed by electroleaching with 10 volt electrode potential on 60 minutes process in 10 % saline solution.
