Abstract
The use of technology in Indonesia has led to an increasing need for electronic and electrical goods, one of which is printed circuit board (PCB) waste. Currently PCB waste reaches 20-50 million tons and will continue to increase every year. Taking into account that the composition reaches around 40% metals including Ag, Cu, Fe, Au, Sn, and Mn, then recycling PCB FR-2 waste can certainly increase added value, one of which is by means of a concentration method to recover these metals. The purpose of this study was to determine the effect of variations in particle size and centrifugal force on the content and recovery of Cu and Ag metals in PCB FR-2 waste using a knelson concentrator. The concentration process was carried out with variations in size -63+100; -100+150; and -150#, and with centrifugal force values of 60, 90, and 120 G Force. The results showed that the size -100+150# and the centrifugal force value of 90 G Force on Cu and Ag metals were considered effective with a mass loss of 3.9%. The levels of Cu and Ag respectively became 67.49% and 0.18%, with recovery values of 53.22% and 39.96%

| Additional Information: | Penggunaan teknologi di Indonesia menyebabkan semakin meningkatnya kebutuhan barang elektronik dan kelistrikan, salah satunya yaitu limbah Printed Circuit Board (PCB). Saat ini limbah PCB mencapai 20-50 juta ton dan akan terus meningkat setiap tahunnya. Dengan mempertimbangkan bahwa komposisinya mencapai sekitar 40% logam diantaranya Ag, Cu, Fe, Au, Sn, dan Mn, maka daur ulang limbah PCB FR-2 tentunya dapat meningkatkan nilai tambah satunya dengan metode konsentrasi untuk mendapatkan kembali logam- logam tersebut. Tujuan penelitian ini untuk mengetahui pengaruh variasi ukuran partikel dan centrifugal force terhadap kadar dan recovery logam Cu dan Ag pada limbah PCB FR-2 dengan alat knelson concentrator. Proses konsentrasi dilakukan dengan variasi ukuran - 63+100; -100+150; dan -150#, serta dengan nilai centrifugal force sebesar 60, 90, dan 120 G Force. Hasil penelitian menujukkan bahwa ukuran -100+150# dan nilai centrifugal force sebesar 90 G Force pada logam Cu dan Ag dinilai efektif dengan mass loss sebesar 3,9%. Kadar logam Cu dan Ag masing-masing menjadi 67,49% dan 0,18%, dengan nilai recovery sebesar 53,22% dan 39,96% | |||||||||
