Abstract
The morphology and spread of micro- and nano-formations on surface of apatite and shtaffelite ore minerals (apatite, shtaffelite and calcite) due to adsorption of fatty-acid collecting agents have been studied using the methods of optical, laser confocal scanning, analytical electron and atomic force microscopy. The Fourier-transform IR spectroscopy has shown that fatty-acid collecting agents are adsorbed on surface of apatite, shtaffelite and calcite in a mixed ion-molecule form; the ion form of attachment prevails for calcite.
