摘要:
This invention relates to particulate and/or liquid droplet separation processes from liquids containing the same and the use of specific chemical additives to control surface wetting, hydrophobicity and surface forces in such processes.
摘要:
Novel compositions comprised of a dialkyl aryl disulfonic acid and a collector different from the dialkyl aryl disulfonic acid are provided, said compositions being useful for beneficiation of ores. Novel methods for using compositions comprised of a dialkyl aryl disulfonic acid and a collector different from the dialkyl aryl disulfonic acid to beneficiate ores are also provided.
摘要:
The present invention provides a method of separating nickel bearing sulphides from mined ores or concentrates of mined ores that contain talc particles is disclosed. The method comprises adjusting the Eh of a slurry of mined ores or concentrates of mined ores and making particles of nickel bearing sulphides less hydrophobic than talc particles and floating the nickel bearing sulphide particles from the slurry.
摘要:
A method for the flotation of sulfide ores is disclosed. The method comprises contacting the sulfide ores with a composition comprising at least one compound of the formula where R1, R2 and R3 independently of one another are alkyl groups having 1 to 18 carbon atoms, alkenyl groups having 2 to 18 carbon atoms, aryl groups having 6 to 10 carbon atoms, or alkylaryl groups having 7 to 10 carbon atoms.
摘要:
This invention relates to processes for modifying the flow characteristics of slurries, particularly mineral slurries such as red mud from the Bayer process, using water-soluble polymeric emulsions to increase the slurries' angle of repose.
摘要:
A process for the selective flotation of at least one sulfide selected from the group of copper sulfide, silver sulfide, and activated zinc sulfide performed in the presence of 2-mercapto-benzoxazole derivatives.
