Gold extraction from ores using non-cyanide lixiviants is currently a significant topic worldwide. Herein, we report the synthesis of an eco-friendly lixiviant that not only is much less toxic than sodium cyanide (NaCN) but also shows excellent effect in the leaching of gold. The lixiviant can be synthesized from roasting of the well-mixed potassium hexacyanoferrate(II) …

we have a small alluvial gold mine and the final concentrate is a mixture of fine gold and cassiterite (tin oxide). When we smelt it, sometimes some part of the tin goes into the gold and makes it grey and brittle. Why that happens, I don´t know . We first thought, it might be the smelting temperature (1200°C).
