摘要： A process and a plant for treating ore concentrate particles containing valuable metal and having at least arsenic and sulfur containing components. The process comprises a two-stage roasting process comprising a first roasting step and a second roasting step. A gas mixture is formed from the first process gas component obtained from the first roasting step and from the second process gas component obtained from the second roasting step. Post combustion of the gas mixture is made in a post combustion chamber that uses the sulphide rich first process gas component and the second process gas component as oxidizer gas in order to decompose SO3 in the gas mixture. The exit gas is exposed to subsequent gas cooling and dust removal steps.

摘要： The invention relates to a method and an apparatus for cooling a material to be removed from the grate of a fluidized bed furnace. Material at a high temperature is passed from the grate of the fluidized bed furnace into a fluidized bed cooler in charges of a given size by measuring the quantity of the material accumulating in the fluidized bed cooler. When the quantity of the material in the cooler has reached a predetermined limit value, the supply of material into the fluidized bed cooler is prevented. The charge is cooled in the fluidized bed cooler by fluidization air and via heat transfer into a cooling liquid circulation system and the temperature of the charge is measured. The charge is removed when the temperature of the charge has fallen to a predetermined limit value. The second end (5) of a supply conduit (3) is provided with a supply valve (15) actuated by a power means (16). A discharge conduit (14) is provided with a discharge valve (17) actuated by a second power means (18). Quantity detection means (19, 20) are provided to produce quantity data regarding the amount of material in a fluidized bed space (11), and temperature measuring means (21) are provided to produce temperature data. A control device (22) controls the first power means (16) to open and close the supply valve (15) and the second power means (18) to open and close the discharge valve (17) on the basis of the quantity data and temperature data and the predetermined limit values of quantity and temperature so that the loading of material into the fluidized bed space and its cooling and removal from the fluidized bed space take place in a charge-by-charge and cyclic manner.

摘要： The present invention concerns a process and a plant for treating ore concentrate particles containing valuable metal and having at least arsenic and sulfur containing components. The process comprises a two-stage roasting process comprising a first roasting step (1) made in a first roasting reactor (16) and a second roasting step (3) made in a second roasting reactor (17). A gas mixture is formed from the first process gas component (2) obtained from the first roasting step(1)and from the second process gas component (4) obtained from the second roasting step (3). Post combustion of the gas mixture is made in a post combustion chamber (6). The post combustion operates with said reducing and sulphide rich first process gas component (2) and the second process gas component (4) as oxidizer gas in order to decompose SO3 in the gas mixture to reduce the SO3 content. The risk of accretion formation and corrosion in the post combustion chamber and in subsequent steps is reduced. Finally the exit gas (7) is exposed to sub sequent gas cooling and dust removal steps (8 to 11).

摘要： A method of operating a fluidized bed deposition reactor to provide top removal of granular material, including production product is set forth. The vertical generally cylindrical reactor has at least one gas inlet at the lower end, at least one gas and solids outlet at the upper end and a gas/granular product separator connected to the gas and solids outlet. A heated reaction zone located in the lower portion of the reactor includes a fluidized bed; the bed being fluidized to establish a bubbling fluidized bed with a defined stable height. A disengaging space is provided above the stable bed height. A reaction gas is added to the bottom of the reactor, the reaction gas depositing a reaction product coating on the granular particles, the coating being abraded off the granules. The combined flow rate of the fluidizing gas and the reaction gas is adjusted so that a majority of the granular particles are retained in the reactor while maintaining bubbling. The height of the bed is increased and the disengaging height above the bed is decreased until the bursting of bubbles near the surface of the bed throws granular particles through the gas and solids outlet to the gas/granular product separator. The flow rates of the gases are controlled to maintain a balance between particles removed by the separator and the average rate of granular particle size increase as adjusted for attrition.

摘要： A method and an apparatus (50) for producing direct reduced iron (37) from dry pellets (25) composed of iron oxide and carbonaceous material. A mixture of pellets (25) and free coke particles (38) with weight relation from 3:1 to 5:1 is fed into the top of an electrothermal fluidized bed (32) that is fluidized by nitrogen. By exposing pellets (25) in the electrothermal fluidized bed (32) to temperatures of between approximately 850-1,100° C. for an average period of between approximately 15-60 minutes, the volatiles are removed and the pellets (25) metallized. Reduced pellets (37) mixed with free coke (38) are discharged from the bottom of fluidized bed (32) and cooled. The reduced iron pellets (37) are physically separated from any free coke (38) and the free coke (38) is recycled back into the fluidized bed (32).
