BIOX Transforms Unviable Projects into Profitable Ones

2020-6-10 · For Velardeña, specifically, gold recovery without BIOX was on the order of 5 to 7 percent. With BIOX, this increases to over 90 percent. What BIOX does is to use bacteria to oxidize the sulphide mineral – essentially dissolving it – thereby exposing the gold particles. Subsequently, cyanide can access the particles and leach them.
