Abstract
The article presents the results of a comparative study of the composition and properties of two commercial flotation reagents on an organic basis. It is shown that both reagents exhibit high flotation activity and complex properties of the collector-foaming agent in the process of enrichment of coking coal slurries. It was found that the component composition of reagents is very different, but has similar efficiency. One of them is represented mainly by h - and cycloaliphatic compounds. The second contains aromatic compounds in comparable quantities. The presence of compounds with oxygen-containing polar groups (cyclic alcohols, ketones, aliphatic acid esters) in both reagents gives them the characteristics of complex reagents with heteropolar properties.
