The article describes laboratory experiments comprising ore dressing and concentration of mineral raw materials by flotation. Samples of ferruginous quartzite and flotation separation products were studied by using precision methods such as X-ray fluorescence analysis, laser diffraction to determine the particle size distribution of the samples.

It has been proven that in the grinding process aminoacetic acid acts as a surfactant reducing the durability properties of the material. The experiments show that at the subsequently stage physical and chemical activation allows a greater amount of silicon dioxide turn into the form of silicic acid at the aqueous phase that leads to chemisorption improvement of the reagent - the collector of minerals in flotation.
