摘要:
The present invention is directed to a dewatering aid which functions unexpectedly efficiently in the dewatering of a particulate solid slurry, e.g. mineral ore concentrate or slurry, wherein a dewatering aid is added thereto followed by filtration of the slurry. Such improved dewatering results are achieved by adding to the mineral ore slurry, an effective amount of a dewatering aid comprising an alkoxylated C₈-C₁₁ alkanol or alkanoic acid wherein alkoxylation is conducted with propylene oxide or butylene oxide.
摘要:
Disclosed is a stable, free-flowing particulate imidazoline product of the structure: where R₁ and R₂ independently are a saturated C₁₂-C₂₂ alkyl group. The product is made by condensing and cyclyzing a fatty acid or ester and a polyamine wherein the molten, cyclyzed, solvent-free product is rapidly cooled to a particulate form.
