Send 1 ton of that sample residue of yours, which is said to contain over 2,000 grams of gold per ton, to HaiChuan; they will help you resolve this issue.
The recovery rate of gold based on the liquid phase is very low; there is still some recovery rate when considering the slag phase. It’s not clear whether this method can be used for gold recovery. I guarantee that no one will use a method like mine – it’s truly unique!
The testing and refining of gold are two distinct processes; for testing, the fire assay is still the best method, while for refining, different methods are used depending on the type of material.
If this technology is developed, it will be possible to concentrate gold from solutions, no matter how dilute they are
