Design and Experimentation Shaking Table Tool for Gravity Concentration Metal Mineral Separation

Abstract

Mineral dressing, especially metal minerals in Indonesia, is carried out using appropriate methods based on their properties and characteristics. The method often used is gravity concentration. The technology that makes use of it is a shaking table. This tool works based on the difference in specific gravity and pаrtіcle size in the flowing film concentration which exerts a thrust against the pаrtіcles on the deck. In an effort to meet the needs of practicum and research in the mining engineering department, especially the Sriwijaya University Mineral Processing Laboratory. For this reason, the existing equipment in the laboratory is modified by changing the design and size of its main components. The deck is designed with a length of 170 cm and a width of 102 cm. The riffles are installed parallel to a height of 3 mm, a width of 1 cm and a spacing of 3 cm. Experimentation is carried out by adjusting the variation of the variables. The variables used as parameters are deck slope (4°, 6° and 8°), water flow rate (10, 12 and 15 L / min) and feedingspeed (5, 10 and 15 minutes). The sample used was refined tin ore. Sampling at two locations, namely sample A at the Bantam B122 Collection Station, Belinyu and sample B at the TKT DU1521 Jangkang Washing Plant Station.
