Remediasi Elektrokinetik Menggunakan Elektroda 2-d Hexagonal Pada Tanah Limbah Pertambangan Emas Yang Mengandung Tembaga (Cu) Dan Merkuri (Hg) Di Kokap Kulonprogo YOGYAKARTA

Amalgamation is used to extract gold in a gold mining at Kokap, Kulonprogo, Yogyakarta by local miners. The equipment of this process is a drum in certain shape or gelundung. To get pure gold, the gold ores that also contain Cu and other metals are heated and the result of this process is called bullion. In the process of purification it will produce a tailing which still contains heavy metals such as Cu, Hg, Cd, etc. To remove Cu and Hg pollutants in the tailing, we used electro-kinetics method by 2D hexagonal configuration with direct current of 40 volt and 0.2 ampere with 15 hours of operation. Every 3 hours the tailing is sampled for analyses of Cu by AAS method. The results show that there is significant decrease in Cu concentration by 61 % and Hg by 36 %.
