Last week I had the opportunity to visit some of the abandoned industrial sites along Hebden Beck in rural upper Wharfedale.

The area was extensively mined until the late 19th/early 20th for lead (galena, lead (II) sulphide) and zinc (sphalarite, a sulphide ore of zinc that also contains iron). The geology is such that, although not mined, there would be cadmium present in the form of greenockite.

The areas of mining spoil are still so barren, even after 100 years, that they look to have been deposited yesterday.
