Comparison of Mineral Processing Methods for Metal Recycling from Waste Printed Circuit Board.

Faster technology development, increasing of living standard and market availability are the main causes of faster obsolescence of electronic devices. Each electronic device contains printed circuit boards that are a valuable source of metal. The paper presents the results of preliminary research of the possibility for using various mineral processing methods in recycling of waste printed circuit boards. The gravity concentration (concentration table and Humphreys spiral concentrator), electrostatic separation and wet magnetic separation were used in this preliminary research and the obtained results were presented in the article.
