flotation models are linked. For example, a laboratory test conducted on a drill core sample, intended to represent a portion of the orebody, is conducted at a specific grind (represented by a P 80). However, when that ore is actually processed through the plant it may well be (and in many cases most likely will be) at another P 80 ...

1. Background. The application of flotation on a reasonable scale within the gold-mining industry commenced in the early 1930s following the introduction of water-soluble flotation collectors (specifically xanthates and dithiophosphate collectors) that allowed differential flotation of sulfide minerals (Weinig and Carpenter, 1937, Rabone, …

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.
