At SION we ensure the gold dust is cleaned up with acid, burnt, XRF tested before it is being smelted by our Assaying Team of Expert. This process will help us to know exactly what is being smelted. Smelting is a process that involves heating and melting and also transform the Gold dust or nuggets to bars. SION’s State-of-the-Earth Gold Testing Laboratory is powered with advance modern-day Gold Laboratory Equipment designed to detect all kinds (bars, nuggets or bars) of gold. At SION our independent laboratory is unmatched throughout West Africa.
