The bigger the density difference between the valuable mineral and the waste mineral is, the easier the DMS separation should be. Dense media separation can be achieved if the valuable mineral is well liberated from the unwanted waste material at a coarse size fraction.

While, under certain conditions, some metals may leach from coal ash wastes (, As, B, Se), many strategic metals remain bound to the waste ash. The range of strategic metal concentrations in some coal ashes are similar to those from mineral ores, suggesting .
The gravity concentration separation process gets more complex as the specific gravities between the valuable mineral and the gangue get closer. For example, complex gold in a sulphide complex of pyrite, must isolate a specific gravity gold pyrite.
Mineral processing: Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of
Ore dressing is a process of mechanically separating the grains of ore minerals from the gangue minerals, to produce a concentrate (enriched. Contact US .
DESCRIPTION: A critical step in the extraction of elements from ore, especially rare earth elements that are found in complex minerals, is separation. 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.
With magnetite, producers can use basic physics to separate the valuable from the worthless while reducing harmful and even toxic byproducts, through dense media separation. Before the development of complex DMS systems, separating valuable product from waste byproducts was challenging.
The conducting materials, which contained the valuable metals, were then used as the feed material for magnetic separation, where it was found that 42% of the conducting materials were magnetic and 58% were nonmagnetic.

Problems with mining waste. It is primarily from waste in the mining of sulphide ores that serious environmental problems can arise due to their content of iron sulphides such as pyrite and pyrrhotite. When mining waste containing iron sulphides is allowed to lie unsheltered and comes under the effects of weather and wind,...
environmental behaviour of mineral fractions from advanced separation of incinerator bottom ash Abstract The present study investigated the properties of eight different samples of incinerator bottom ash, derived from an enhanced separation process aimed at materials recovery, and recycling of the valuable fractions (mainly...

Copper extraction. The processing techniques depend on the nature of the ore. If the ore is primarily sulfide copper minerals (such as chalcopyrite ), the ore is crushed and ground to liberate the valuable minerals from the waste ('gangue') minerals. It is then concentrated using mineral flotation.
