Step 1: Milling. When ore enters the plant from underground it first needs to be milled to reduce its size so that the gold is liberated from the host rock. South Deep's milling circuit consists of a single-stage semi-autogenous grinding mill (SAG) and a pebble crusher for primary milling, followed by secondary milling using two overflow ball ...

Gold ores were obtained from the Gasado gold mine in Jeollanam-do, Korea. It is known that the gold ore consists of pyrite, muscovite, and quartz [30]. The gold ores were initially crushed using a jaw crusher and a cone crusher, and then ground using a ball mill in the gold ore beneficiation plant. Water was obtained from the plants.
