Document Type and Number:
WIPO Patent Application WO/2020/019777
Kind Code:
A1
Abstract:
Disclosed is a method for producing a zinc-containing complex or zinc oxide using a zinc-containing raw ore via an intermediate step for the synthesis of calcium zincate. The method for producing a zinc-containing complex using a zinc-containing raw ore via an intermediate step for the synthesis of calcium zincate comprises an extraction step, an optional purification step, a decarburization and precipitation step, a calcium zincate synthesis step, an optional rinsing step and a calcination step; and the method for producing zinc oxide using a zinc-containing raw ore via an intermediate step for the synthesis of calcium zincate comprises an extraction step, an optional purification step, a decarburization and precipitation step, a calcium zincate synthesis step, an optional rinsing step, a calcination step and a calcium-zinc separation step.
