Improved Coal Flotation with Sinterol Modifier | SpringerLink

Abstract The flotation of coal with different ash content when using Sinterol modifier is studied. If the modifier consumption is 1.0–3.0 g/t of coal fines, the extraction of the coal's combustible mass in the concentrate is increased; the selectivity of the process is increased; and the loss of the coal's organic mass with the flotation wastes is decreased. The …
