Froth Flotation and Gold Extraction
First, refractory gold ore is ground as finely as possible – usually so the individual grains are much less that 100 micrometers. The ground up ore is mixed with water to create a slurry, which is mixed with surfactants to increase the gold's hydrophobicity. This mixture is placed into a tank or flotation cell filled with distilled water.

Flotation of Gold and Gold-Bearing Ores
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, …

Analysis of Lead-Zinc Sulfide Ore Flotation
Lead-zinc ore is a polymetallic mineral rich in elemental lead and zinc, mainly in lead-zinc sulfide and lead-zinc oxide ore. Among them, lead-zinc sulfide ore is an easy-to-select ore; lead-zinc oxide ore is a difficult-to-select ore. Due to the increasing global demand for lead-zinc mineral resources, both lead-zinc ores are valuable for mining.
