    Abstract: A method of stabilizing a fluidized bed in a fluidized bed roasting process for metal sulphide concentrate comprises the step of controlling the particle size distribution of the particulate material in the bed so that a minimum amount of no less than about 30 % of the concentrate falls in a size range of from about 100 to about 420 mu m. The minimum amount preferably falls in the range of from about 35 % to about 40 %. In one embodiment of the invention the particle size distribution is controlled by maintaining the amount of lead in the concentrate in a range from about 3 % to about 4 %, preferably 3.7 % to about 3.8 %. In another embodiment the particle size distribution is controlled by using a pelletized feed or by the combination of the steps of using a pelletized feed and regulating the lead content of the concentrate.

    Abstract: Regeneration of hydrochloric acid by hydrolysis of iron chloride in aqueous solution employs a Pelletiser (5) after preconcentration of acid solution in a "Pre-Evaporator" (1). Pelletiser (5) controls pellet mixture to between 12 % and 14 % free water by recycling dried solids from Roaster (3), from Screen (7), or from dust removal Cyclone (9), and waste liquid from Preconcentrator (1). Preconcentrator (1) is contacted with superheated gas from Fluid Bed Roaster (3). Rotary Drier (6) dries pellets with a con-current hot gas stream and the pellets are screened at (7) with oversize being sent to a Mill (8), undersize recycled to Pelletiser (5), and sized feed delivered to Roaster (3). HC1 is produced as gas offtake from Preconcentrator (1) and passes via a demisting Cyclone into adiabatic Absorption Process section (11), where weak acid liquor and water (10) are added as required.
