摘要： A method for forming a turbulent suspension from a pulverous material and reaction gas by causing the pulverous material to flow downwards as an annular flow into the reaction chamber and by directing the reaction gas downwards inside the annular flow of the pulverous material, in which the suspension is produced by bringing the reaction gas into a high-force rotary motion and by then causing it, throttled, to discharge into the reaction chamber so that in the reaction chamber it meets on its outside a substantially vertically downward annular flow of the pulverous material, this flow being formed by utilizing the kinetic energy of the falling pulverous material on a convergent conical glide surface. An apparatus for forming a turbulent suspension from a pulverous material and reaction gas, which apparatus is adapted to be directed centrally downwards into the reaction chamber and consists of a feed pipe for the pulverous material, means for dividing the pulverous material and of a turbulence chamber for reaction gas, in which the feed pipe for the pulverous material has the shape of a downwards convergent cone, and inside the feed pipe there is an axially mounted turbulence chamber at the upper section of which there is a turbulence generator, and the lower section of the turbulence chamber comprises a cylindrical stabilizing member with a diameter less than that of the turbulence chamber.

摘要： The invention relates to a method for oxidizing the pulverous fuel of a furnace, advantageously a flash smelting furnace, by means of a burner, so that the oxidation takes place mainly owing to an effective mixing of two different combustion gases, pulverous fuel and possibly an extra fuel in the furnace space. The combustion gases are conducted into the furnace space in separate flows, so that oxygen is fed in through the center in an at least partly turbulent flow, and the air is fed around it in several separate flows. The invention also relates to a burner for mixing pulverous fuel and combustion gas and for burning them in the said furnace space.

摘要： The present invention relates to a method for concentrating a certain mineral fraction attached to air bubbles from a slurry to the foam layer accumulated on the surface, so that the concentration takes place in three different mixing zones. The apparatus of the invention is formed of a colon-like flotation arrangement and of flow guides, a flow attenuator and an agitator belonging thereto. The flotation reactions are created in the bottom zone, wherefrom air bubbles and mineral particles carried by them are directed in a controlled fashion onto the surface of the apparatus. The flotation apparatus is so designed, that a strong agitation in the bottom zone can be used without causing harmful separation of the foam in the bottom part of the apparatus.

In the apparatus of the invention, to the circulation cylinder (6) of the mixer there is connected the heavy phase return conduit (27) and the light phase return conduit (29) entering from the settler of the same extraction step. In the top part of the mixer, coaxially with the turbine pump (9), there is installed the dispersion pump (12) where the dispersion rises to above the liquid surface (8) of the mixer through 2-24 rising pipes (15). The top ends of the rising pipes (15) are connected to the circular pipe (18), wherefrom the dispersion flow is conducted to the next stage through the collecting trough (22).

摘要： A process for the suspension smelting of sulfide concentrates by causing a suspension flowing downwards in a suspension reaction zone to impinge against the surface of a melt below the suspension reaction zone in order to unload the solid and molten particles of the suspension into the melt and by causing the gases to flow further in the suspension reaction zone countercurrently in relation to the suspension in order to discharge the gases from the upper section of the suspension reaction zone, in which sulfide concentrate and oxygen or oxygen-enriched air are fed into the suspension reaction zone symmetrically and in the form of so dense a suspension spray that the iron oxide of the high-temperature suspension is in a molten state and absorbs the free oxygen present in the suspension before the suspension, at a temperature of at least 1400.degree. C., unloads into the melt, the heat is recovered indirectly in the suspension reaction zone from the gases rising symmetrically and smoothly around the suspension, and the melt is fed from the suspension reaction zone into a separate melt reaction space.
