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.

Aug 31, 2016· Gold is often found on printed circuit boards, particularly under keyboards where its durability is an advantage. According to the UE researchers, about 300 tonnes of the metal are used in

Analysis of kerosene concentration (RIL process

Analysis of kerosene concentration (RIL process

You will use kerosene and an ionexchange resins to adsorb the gold. There are not many operations using a resin process (RIP, RIL or RIS). The advantages of the resin over activated carbon are the better gold loadings and the resistance to fouling by the addition of kerosene. The kerosene addition ranges from 5 to 10 L/t of ore. It is small dosage.

Mar 24, 2021· Signet converted the CIL circuit to an RIL circuit using Vitrokele resin. The resin proved impervious to kerosene, but not to copper. The copper occupied gold sites and substantially reduced the resin activity. Penjom then changed to a goldspecific resin having been convinced that resin was a practical viable alternative.
