Abstract
The present invention relates to a process for concentration of silicate-containing minerals and ores by froth flotation, in particular to a reverse flotation process, in the presence of a finely dispersed collecting agent characterized by a specific droplet size distribution.
Claims7
A nanoemulsion, comprising at least one collector for the flotation of silicate minerals from other minerals, at least one emulsifier, and water, wherein water forms the continuous phase, the average particle size of the collector is from 1 nm to 6 μm, and wherein the collector is a compound comprising at least one nitrogen atom and at least one hydrocarbon group having 6 to 30 carbon atoms;
- and wherein the collector is present in an amount of 20 to 60 wt.-%, based on the total weight of the nanoemulsion.
