A method for removing suspended particles from a liquid by means of gas-bubble flotation, in which, before the gas-bubble flotation step proper, the liquid is more or less saturated with the gas in one or more preceding gas introduction steps, so as to obtain a longer average life-time of the smaller gas bubbles in the final flotation step.

In a process for gasification of solid carbonaceous material such as coal powdered, coal is top-blown by a carrier gas onto a molten iron bath stored in a furnace through a non-submerged lance toward a hot spot formed by means of jet of oxygen and steam top-blown through a non-submerged lance and flux is optionally added into the furnace by the lump or blown toward the hot spot, thereby coal being...
