Abstract RU 2455077 C2

FIELD: process engineering.

SUBSTANCE: invention relates to ore dressing. Proposed method comprises making suspension containing mineral ore particles, mixing it with efficient amount of composition of agents for foam flotation containing dithiocarbamate of formula (I) : where every R and R¹ comprises substituted C_1-20 alkyl, substituted C_6-20 aryl, substituted C_2-20 alkenyl or substituted C_7-20 aralkyl. Said composition of agents for foam flotation contains combination of formula (I) and, at least, one more ingredient selected from the other foam flotation agent.

EFFECT: higher efficiency.
