We are restoring the mill’s roof by hand to preserve history for generations to come. Read more about the tin mill restoration here.
The first step of the Tolgus Mill is to use huge stamps to crush the rocks into ‘sands’ and even finer ‘slimes’, releasing the tin that’s bound within the rock.
Once it’s crushed the mill uses an array of ingenious Cornish machinery, like a shaking table, to separate this black tin ore (Tin Oxide – SnO2) from the crushed rock.
When a high percentage of black tin ore is reached, we smelt it by heating it to around 1400°C with coal to remove the oxygen and create pure, shiny white tin.
By incorporating the tin we mill into our Tolgus jewellery collection, we are sustainably protecting and maintaining Tolgus – the last working Cornish tin streaming mill.
Our latest exhibition will allow you to discover the history behind Tolgus, see how it worked, discover the machinery and much more. Learn how rock from local tin mills was pulverised, and explore the ingenuity and human stories behind this last working link to Cornwall’s past.
