Process for the selective froth-flotation of sulfidic, oxidic and salt-type minerals
A process for the selective froth-flotation of sulfidic, oxidic and salt-type minerals, whereby an ore is first wet ground to the flotation fineness to obtain a slurry and then the obtained slurry is prepared and froth-flotated. In addition to the collector agent a polysaccharide, lignosulfonate, qu...

description | A process for the selective froth-flotation of sulfidic, oxidic and salt-type minerals, whereby an ore is first wet ground to the flotation fineness to obtain a slurry and then the obtained slurry is prepared and froth-flotated. In addition to the collector agent a polysaccharide, lignosulfonate, quargum and/or a surface active additional chemical is used which prevents the collector agent from adhering to the silicate surfaces and passivates active silicate mineral surfaces, or weakens the hydrophobia of minerals to which the collector agent has already adhered. The collector agent and the additional chemical may be added as early as the wet-grinding stage. |
