Acetylenic alcohols are studied in coal flotation with different feed density to the flotational machines (70–200 kg/m3). Acetylenic alcohols act as both foaming agents and collection agents. That considerably decreases the consumption of the primary collection agent in flotation; increases extraction in the concentrate; and improves concentrate quality. Crushable foam is produced in flotation using DMIPEC flotation agent. When using monoatomic alcohols as the foaming agent, the yield of concentrate increases with increase in density of the pulp. At the same time, the concentrate’s ash content decreases considerably. With increase in density of the pulp beyond 100–140 kg/m3, the quality of flotation declines considerably. That is not the case when DK-90 and DMIPEC acetylenic alcohols are used as the foaming agents.
