Process and plant for heat treatment of sulphide ore using an annular fluidized bed |
| abstract |
The invention relates to a process and a plant for heat treatment of sulphide ore, where solids are heated to a temperature of about 450 to 1500 ° C in a fluidized bed reactor (1). In order to improve energy utilization, it is proposed to introduce a first gas or gas mixture from below through a gas supply pipe (3) and into a mixing chamber (7) in the reactor (1), which gas supply pipe (3) is at least partially surrounded by a stationary annular fluidized bed (35) fluidized with fluidized gas supply. The gas velocity of the first gas or gas mixture as well as the fluidization gas of the annular fluidized bed (35) is regulated such that the particle fractions in the gas supply tube (3) will be between 1 and 100, in the annular fluidized bed (35) will be between 0.02 and 2, and in the mixing chamber (7) will be between 0.3 and 30. |
