Mining platinum in placer deposits is a relatively simple process. Dredges scoop the platinum-bearing sand or gravel from riverbeds or mining pits. The material is washed until platinum grains or nuggets are captured and pulled from the surrounding material. Sperrylite, or platinum arsenide. Photo from Thomas A. Loomis, Dakota Matrix Minerals.

• Recycling a tonne of copper uses 20% of the energy that would be used to mine and extract the same copper. • The copper recycling process has much in common as that to extract it, but requires fewer steps. High-purity copper is melted in a furnace and then reduced; Low-purity copper is refined through electroplating in sulfuric acid.
