Beschreibung
Zusammenfassung:	The invention relates to fluidization technique for zinc oxide crude ore, which comprises: breaking and grinding the crude ore, conditioning; pumping the top of cone-shaped reactor and acid liquid from bottom of reactor; leaching out; neutralizing the leached liquid in container; condensing in device; cleansing the supernatant to enter another reactor for further acid fluidization; filter-pressing the acid-leached pulp; conveying the filter liquid to ball grinding for conditioning; stacking the slag. Third invention decreases in-tank time of slag and zinc loss, increases zinc leaching efficiency, and cuts cost.
