EFZERO gold refining plant can be fed with grain or better with thin powder (150-600 micron). The powder is the most efficient solution in order to increase the exposed surface area thus making the process faster and reducing the quantity of undissolved gold, compared with the standard grains.
For refining, gold bearing alloys are processed on different methods, depending on their carat content. Two methods are commonly employed for purification: the Miller process and the Wohlwill process. Alternatively, it can be a complex mix of burning, drying, grinding, screening, blending and sampling for low-grade scrap and floor sweepings.
