FLOTATION PROPERTIES OF BASE MINERALS IN EGORIEVSK NODULAR PHOSPHORITE

The article describes laboratory research data on flotation properties of the Kola apatite, phosphate, glauconite, quartz and calcite contained in nodules at the Egorievsk deposit. Experimental flotation of the listed pure mineral particles -0.074 +0.040 mm in size involved both conventional agents and new surface-active chemicals, such as FF-12T, which possess multifunctional properties and are unsusceptible towards flotation pulp content of slimes and calcium and magnesium salts. The research results demonstrate successful applicability of new agent FF-12T in flotation of low-grade rebellious nodular phosphorite ore.
