Abstract

PURPOSE:To obtain flotation collector having high dressing effect by adding polyalkylene oxide deriv. having a specified mol.wt. and contg. a specified proportion of propylene oxide to a flotation collector. CONSTITUTION:A polyalkylene oxide deriv. having 400-200,000 average mol.wt. contg. >=5mol propylene oxide in a molecule is added to a flotation collector. Said polyalkylene oxide deriv. is obtd. by adding propylene oxide to a compd. having active H. Examples of the compd. having active H are alcohols, phenols, carboxylic acids, amines, alkanolamines, mercaptans, amides, amino-acids, etc. The amt. to be used of the flotation collector is 0.01-2wt%. The flotation collector has superior dressing effect for several ores (e.g. chalcocite). When it is used as a flotation collector for pulverized coal, superior deashing rate is attained.

Description

[Detailed description of the invention]

Flotation method IJ has been known for a long time as a method of sorting minerals and coal. This is usually achieved by grinding ores into a fine powder, making a water slurry, placing it in a beneficiation machine, adding a collecting agent, a foaming agent, and a conditioning agent depending on the platform, stirring, and blowing air. This is a method of solidifying the substance to be mixed into foam (J) using an appropriate method. = J is easy to do (if Ij public is b',) b, and conventionally) Answer 1-, A) 1j
