Abstract
A foam flotation process for the separation of silica from iron ore, which consists in the flotation by foam of said ore in an aqueous medium containing a mixture of water-dispersible salts of normal primary alkylamines and acids, containing to 12 successive chains of 8 to 22 carbon atoms, including the chains with even and odd numbers of carbon atoms, the main proportion of the constituents being found near the center of the chain length range and separating the silica by flotation of said ore .
