Placer (alluvial) ore deposits

Placer deposits are an important source for gold, tin, titanium, platinum group elements, and many others. Placer deposits form via sedimentary processes in various types of environments, due to the differences in the density of different minerals. But apart from density, the minerals need some other, quite specific properties, too. In this video, Dr Taija Torvela has a look at how placer deposits form.
