Local mineral smelting workshop for kids

Step 1. Grind up mineral-rich rocks found in the area, including Hematite,  Galena and earthy Malachite and Azurite.

Step 2. Smelting. To smelt iron oxide, charcoal was used to covert the oxygen into carbon dioxide, leaving iron. To smelt galena, lead sulphide, heat alone released the sulphur, leaving lead (seen below).
