Karat 24 projects Gold Refining Plants

This gold refining plant is able to treat from 300 gram. up to 10 kg. of starting gold alloy. You are able to produce 99.99% pure gold (Au) in a single step within a production cycle that can last from 5 to 8 hours, from the preparation of the grains, to obtaining the pure ingot. The treatment takes place by dissolving the staring metal alloy through the use of the so-called “Aqua Regia” solution, an opportunely calibrated mixture of hydrochloric acid (HCl) and nitric acid (HNO3).
