Abstract
"Process for obtaining calcined zinc", starting from zinc sulphide mineral, characterized by maintaining a temperature of the order of 815 to 900º C, a fluidized bed containing particles of zinc sulphide mineral, partially toasted, of a smaller size those that pass through the 100-mesh sieve, and particles of zinc sulphide ore, practically completely toasted, larger than those that cross the 100-mesh sieve; by introducing zinc sulphide ore containing iron and with particles smaller than those passing through the 100-mesh sieve, and particles larger than those passing through the 100-mesh sieve, inside the bed, at a point located below the upper surface thereof and about 15 to 90% above the lower surface of the said bed; by passing a gas containing oxygen through the bed, in order to keep it in a state of fluidization, to partially oxidize the introduced sulfide mineral and to detach and drag out partially roasted particles out of the fluidized bed, in suspension form. , lower than those passing through the 100-mesh screen, by passing the suspension of partially introduced roasted mineral in the gas from the top of the bed through a free space maintained at a temperature of the order of 815-955º C, and a volume at least 7 times that of the fluidized bed, to carry out the practically complete oxidation of the suspended sulfide mineral and converted it into the corresponding oxide; by discharging the virtually completely roasted mineral and the gas from the free space, and by separating particles of roasted ore from the gas, maintaining a temperature of at least 790º C before and during separation.
