Abstract
Pemurnian logarn tembaga dari batuan Kalirejo telah ditentukan dengan eksperirnen elektrokimiawi. Konsentrasi Cu hasil destruksi ditentukan dengan analisa AAS setelah didestruksi menggunakan kombinasi pelarut asam sulfat, asam florida dan asam nitrat pada temperatur 300 ()C secara bertahap. Elektrolisis dilakukan pada potensial 1,0 Volt di atas nilai potensial dekomposisi yang ditentukan dengan elektrolisis basil destruksi standar dan destruksi sampel dengan interval 0,2 Volt. Hasil eksperimen menunjukkan dengan destruksi dar. metode elektrokimia dapat meningkatkan kemumian tembaga dari kadar 0,58 % menjadi 93,00 % dengan randemen Faraday 71,37 %. The purification of copper from Kulonprogo rocks has been determined experimentally by means of electrolytical methods. Concentration of copper destruction product solution was determined by Atomic Absorption Spectroscopic after destructed from using solvents combination of sulfuric acid, fluoride acid and nitric acid under the temperature of 300 . Electrolysis was pet Formed under the applied potential of 1.0 Volt, which more higher than decomposition voltage by measuring the electrolysis standard destruction product and swivel destruction product by which in 0.2 Volt of interval Experimental result showed that destruction and electrochemical method increasing coppzi. purification from 0.58% to 93.00 % which Faraday's randemen is 71.37 %.
