Real wrought iron
Above you can see some of the wrought iron plates we are experimenting with. The iron comes from Chris Topp & Co. based in Thirsk, Yorkshire. They are the only supplier of real wrought iron left in the country and they have an amazing workshop where roll their own plate iron. We got the plate cut down by LaserMaster based up at United Downs near Redruth. Initial experiments with running a copper solution over the plate proved very successful. The displaced copper was apparent after only a few seconds of exposure to the iron plate. However this was a very concentrate solution (30g/L) so it will be interesting to see what results we get when we immerse the plate in tailings up at Wheal Maid. |
