Abstract

Un método para la reduccion de oxido de cobre (1) pulverizado en cobre metálico en estado solido por medio de un gas de reduccion alimentado en un horno hermético de gas que está equipado con una correa sinfín. El oxido de cobre T(1) que se va aalimentar en el horno se seca y calienta, después de lo cual se efectua la reduccion a una temperatura entre 600 y 900°C, por lo menos parcialmente, por medio de hidrogeno y el cobre metálico formado se enfría, después de lo cual se retira el sínterde cobre del horno. El aparato comprende un dispositivo de alimentacion de oxido de cobre (1), un horno tubular hermético de gas en el que circula una correa sinfín. Además, el aparato incluye equipo para enfriamiento, retirar y descargar elmaterial reducido desde las correas así como equipo para alimentacion del gas de reduccion en el extremo de descarga del horno y para la remocion del mismo del extremo de alimentacion del horno.A method for the reduction of copper oxide (1) sprayed in solid copper metal by means of a reduction gas fed into a gas-tight furnace that is equipped with an endless belt. The copper oxide T (1) to be fed in the oven is dried and heated, after which the reduction is carried out at a temperature between 600 and 900 ° C, at least partially, by means of hydrogen and copper formed metal cools, after which the copper sinter is removed from the oven. The apparatus comprises a copper oxide feeding device (1), a gas-tight tubular furnace in which an endless belt circulates. In addition, the apparatus includes equipment for cooling, removing and unloading the reduced material from the belts as well as equipment for feeding the reduction gas at the discharge end of the oven and for removing it from the feeding end of the oven.
