Abstract


Indonesia is categorized as an industrial country that produces a lot of metal waste, so it is necessary to process this metal waste. One way of processing metal waste is that it can be used as pigment. Pigments are natural substances that give rise to color, namely optical properties whose applications are endless, almost all industrial fields really need pigments, from the ceramics industry, paint industry, and plastics industry to batik craftsmen who also need pigments or dyes. The method used in this test is hydrometallurgy, which consists of a leaching process and recovery. In this research, the pigment was produced oxide red from iron wool raw materials. The weight of the oxide red pigment obtained for Experiment 1: 0.20 grams, Experiment 2: 4.96 grams, Experiment 3: 2.63 grams, Experiment 4: 2.22 grams. Then the yield obtained in Experiment 1: 0.204 grams of pigment/gram of iron, Experiment 2: 1.984 grams of pigment/gram of iron, Experiment 3: 1.052 grams of pigment/gram of iron, and Experiment 4: 0.888 grams of pigment/gram of iron. The conversion obtained in Experiment 1: 60%, Experiment 2: 74%, Experiment 3: 81% and Experiment 4: 78%. The pigment results obtained using this method can be further applied in industry because the conversion results obtained are quite high.
