Eddy current separation for recovery of non-ferrous metallic
For example, the global average ore grade of copper has decreased from 1.1 wt% in the 1970s to about 0.8 wt% in 2009 (Crowson, 2012). Thus, to maintain consistent production levels, a larger amount of material must be mined and processed accordingly, which only results in further environmental impacts (Norgate and Haque, The process of separating a metal from its ore is known as smelting. Smelting is widely practiced today and has a long history dating back to the Bronze Age, when ancient peoples first learned the technique. Smelting methods range from the basic to the high-tech, and are applied to a variety of materials, including aluminum, iron and copper.Ways to Separate Metal From Ore Sciencing

Materials Free Full-Text Gravity and Electrostatic Separation
This study proposed an evaluation of enrichment processes of obsolete Printed Circuit Boards (PCBs), by means of gravity and electrostatic separation, aiming at the recovery of metals. PCBs are the most important component in electronic devices, having high concentrations of metals and offering a secondary source of raw materials. A gravity concentrator namely “vibrating table” has been developed with the objective of increasing the product quality of density based physical separation processes. The system is mainly composed of a vibration unit, an inclined chute, TW and WW jets. The principle idea of the separation is to combine the involved forces of a A new method for gravity separation: Vibrating table gravity
