Leaching & Adsorption Resource Book

The gold must be in a fine particulate form (from the grinding circuit). The feed slurry must have an 80% passing size of 75um to achieve suitable gold recovery (refer to cyclone and grinding modules). If the particles are too large they may not be totally leached during their residence time in the tanks and hence will report to tailings.
