Why do large pieces of sulfur sink in water, while sulfur powder floats? How can sulfur ores be separated from waste rock in practice? What is the name of this method of ore enrichment?
Large pieces of sulfur are drowned in water by gravity, and the powder floats up, because it is lightweight and does not wet with water.
Like sulfur, many natural sulfur compounds are not wetted by water when ground. they float on the surface of the water. and the impurities settle. This property is used by the day of separation of ores from waste rock. This method of ore beneficiation is called flotation.
