In a classifier including a rotary disc provided on a lower end of a vertical rotary shaft depending from the top of a hopper-type casing, a horizontal dispersing disc is provided directly below the top of the casing, a circular collision plate is spaced from the outer circumference of the horizontal dispersing disc, and a plurality of vortex adjusting members are secured at their upper ends to the horizontal dispersing disc and at their lower ends to the rotary disc, and a leakage prevention apparatus is provided which comprises a plurality of dispersing and classifying vanes spaced from the outside of the vortex adjusting members and the inner sides of the collision plate. The dispersing and classifying vanes depend from the under surface of the horizontal dispersing disc for an appropriate length. Furthermore, the leakage prevention apparatus can also comprise a ring for preventing the introduction of coarse powder which is provided on the outer circumference of the horizontal dispersing disc, the ring depending from the under surface of such horizontal dispersing disc for an appropriate length.

THE BENEFICIATION ACCORDING TO THE PRESENT INVENTION IS CARRIED OUT BY COMMINUTING THE STARTING COMPLEX SULFIDE ORE (INCLUDING SO-CALLED BLACK ORE), WHILE BEING CONCURRENTLY AIR-DRIED, THE COMMINUTED DRY ORE IS THEN FORTHWITH PULPED, AND THE PULP IS SUBJECTED TO LEACHING WITH E.G. WATER TO LEACH OUT WATER-SOLUBLE CONSTITUENTS THEREFROM. FILTRATION SEPARATES THE WATER-INSOLUBLES FROM THE FILTRATE. ROUGH FLOTATION SEPARATES THE FILTER CAKE INTO A PYRITE CONCENTRATE AND A COPPER AND ZINC CONCENTRATE. THE LATTER IS SEPARATED INTO A COPPER CONCENTRATE AND A ZINC CONCENTRATE BY DIFFERENTIAL FLOTATION, FOLLOWING CONDITIONING. CYANIDE SOLUBLES ARE REMOVED FROM THE ZINC CONCENTRATE. WASH WATERS AND FILTRATES FROM THE LEACHINGS ARE RECIRCULATED AND RE-USED.

An ion generating device generates O2−(H2O)n (where n is a natural number) as negative ions and H+(H2O)m (where m is a natural number) as positive ions, and discharges those ions into the air so that airborne germs are killed through an oxidation reaction by hydrogen peroxide H2O2 or radical hydroxyl OH generated through as an active species a chemical reaction between the negative and positive ions. Satisfactory sterilization is achieved when the negative and positive ions are generated in such a way that the concentrations of the negative and positive ions are both 10,000 ion/cc at a distance of 10 cm from the point at which they are generated.

摘要:
A desired number of cables are drawn, along with the falling charge, into a blast furnace from its top and the forward ends of the cables are melted upon reaching the melting zone in the furnace. The length of each of the cables to its melted end is measured in accordance with the result of a voltage pulse response measurement utilizing the distributed constant circuit characteristics of the cable, and the height level of the melting zone inside the furnace is measured from the cable length by correcting it for the amount of deflection of the cable within the furnace. By measuring the cable length at each of a plurality of radial locations of the furnace, it is possible to estimate the three-dimensional shape of the upper boundary of the melting zone with a high degree of accuracy.
