摘要
The invention relates to a method of enrichment of iron mineral from silicate-containing iron ore by reverse flotation, including the addition of a collecting agent or a composition of a collecting agent containing at least one compound of formulas: in which X is a linear or branched aliphatic alkylene group containing 2-6 carbon atoms; Z means a linear or branched aliphatic alkylene group containing 2-6 carbon atoms; Y means an anion and R means an aliphatic group of formula (I) in which the CH is part of the aliphatic group of formula (I) consists of 70-99% by weight of n-CH and 1-30% by weight of CHCH (CH) CH- and / or SNCH (CH) SNCH-.
