Process for froth flotation of silicate-containing iron ore |
摘要 |
The present invention relates to a process for enriching an iron mineral from a silicate-containing iron ore by carrying out, at a pH of 8-11, a froth flotation in the presence of a depressing agent for the iron mineral and a collecting agent containing a combination of an ether monoamine and an ether polyamine, which contain an aliphatic hydrocarbon group having 6-22 carbon atoms in a weight ratio of the ether monoamine to the ether polyamine of 1:4-4:1. The invention also discloses a composition which is suitable for use in the process.
