Further exploration programs could be initiated to target the conversion of Inferred Mineral Resources to Indicated Mineral Resources. The Selinsing Gold Mine has a proven record in converting oxide Inferred Mineral Resources to recovered ounces. The diagram below shows conceptual flotation and BIOX® circuits added to the gold recovery process.
Spiral Separators for heavy minerals. Our gravity separators for heavy mineral applications, including iron ore, chrome, mineral sands and other high density minerals, separate particles in the size range 2 to 0.04 mm.. We have a range of spirals, from 3 to 12 turns, with high-, medium- and low-gradient profiles.
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, …

Steps in the Flotation Process. The flotation process is a widely used method for separating minerals from their ores. It relies on the differences in surface properties of the minerals to be separated. Here are the steps involved in the flotation process: Grinding: The ore is first crushed into a fine powder through the process of grinding.
Flotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic condition—that is, the surfaces are either repelled or attracted by water. The flotation process was developed on a commercial scale early in the 20th century to
