Placer 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.

It’s wonderful to see a fairly niche topic like economic geology getting some time in the spotlight of such clear presentations. Well done!

Thank you. I love your videos - they make so much sense of something that's always been a bit opaque to me. I didnt even know how to pronounce 'placer' until now!

The unfortunate Dutch Afrikaner's - trying to rid themselves of the British and their commercial allies - went on their Great Trek to find autonomy and going North landed in that region with Witwatersrand - of course that meant Diamonds and Gold which meant the Dutch would never be free - as is the case today - $$$ does not equal freedom

My grandparents lived in Placerville, California. Placer mining for gold was a big thing in the Sierra Nevada foothills in the 19th century to the extent that some of the first environmental laws in the USA were enacted because of the massive silt runoff from the mining operations which were starting to fill in the Siusun and San Francisco Bays.
