Definitions

  • the invention relates to a process for the extraction of minerals from non-sulfidic ores by flotation, in which detergent mixtures containing salts of sulfated unsaturated fatty acids and sulfated unsaturated fatty acid glycerol esters, optionally in a mixture with other anionic and / or nonionic surfactants, are used as collectors.

  • the ore is first ground and dry, but preferably wet, and suspended in water.
  • a collector is added, often in conjunction with other reagents, which include foaming agents, regulators, pushers (deactivators) and / or Beieber (activators), to separate the valuable minerals from the gangue minerals in the ore during the subsequent flotation supports.
  • these reagents are usually allowed to act on the finely ground ore for a certain time (conditioning).
  • the collector causes the surface of the minerals to become hydrophobic, so that these minerals adhere to those formed during ventilation. gas bubbles take place.
  • the mineral constituents are made hydrophobic selectively in such a way that the undesired constituents of the ore do not adhere to the gas bubbles and remain behind, while the foam containing the mineral is stripped off and further processed.
  • indirect flotation the contamination is flotated out, while the valuable mineral remains.
  • the aim of the flotation is to obtain the mineral of value of the ores in the highest possible yield and at the same time to obtain the best possible enrichment of the mineral.
  • collectors In the flotative processing of non-sulfidic ores, mainly anionic or cationic surfactants are used as collectors.
