slag slag is the glasslike byproduct left over after a desired metal has been separated (i.e., smelted) from its raw ore.slag is usually a mixture of metal oxides and silicon dioxide.however, slags can contain metal sulfides and elemental metals. while slags are generally used to remove waste in metal smelting, they can also serve other purposes, such as assisting in the temperature control ofcrusher a crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust.. crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.1 froth flotation fundamental principles1 froth flotation fundamental principles froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. the particles with attached air bubbles are then carried to the surface andfile size 659kb

Advantages of mineral sorting techniques froth flotation

mechanical screening mechanical screening, often just called screening, is the practice of taking granulated ore material and separating it into multiple grades by particle size.. this practice occurs in a variety of industries such as mining and mineral processing, agriculture, pharmaceutical, food, plastics, and recycling.. a method of separating solid particles according to size alone is called screening.froth flotation an overview sciencedirect topicsthe froth flotation process is commonly employed for the selective separation of a mineral species from a liquidsolid suspension of both valuable and unwanted gangue mineral particles. the valuable mineral species (which needs to be separated) is rendered hydrophobic by controlling its surface chemistry to provide the potential conditions for the attachment of the particles to air bubbles.
