Description
Technical field
The present invention relates to technical field of beneficiation, and the alkaline process handling process of more particularly to a kind of lithium ore.
Background technology
The lithium minerals that is found in nature and ore deposit containing lithium kind up to more than 150 at present, China's lithium resource rich reserves,
The lithium resource gross reserves verified occupies second place of the world.Lithium ore deposit is mainly used in extracting utility therein, and lithium is produced wherein being used as
The raw mineral materials of product is mainly spodumene and (contains 5.8%~8.1%Li2O), lepidolite (contains 3.2%~6.45%Li2O), phosphorus
Lithium aluminium stone (contains 7.1%~10.1%Li2O), petalite (contains 2.9%~4.8%Li2O) and zinnwaldite (containing 1.1%~
5%Li2O).It is worthy of note that, most widely used lithium product is lithium carbonate, is the basis of the secondary lithium salts of production and lithium metal
Material, thus be the lithium product of most critical.
It is many at present that lithium carbonate is extracted in lithium ore using wet method smelting process, such as during from spodumene as raw material,
Containing about 6.0% lithia, 0.12% rubidium oxide and 0.039% cesium oxide in spodumene, conventional sulfuric acid process is carried
Lithium technique is：Spodumene is calcined in 1050~1200 DEG C, the spodumene of α types is converted into the spodumene of β types, then by β
The spodumene of type is finely ground to 200 mesh, and batch mixing is carried out with the concentrated sulfuric acid (content more than 95%), is subsequently placed in 350 DEG C or so of acidifying
Acidizing fired in cellar for storing things, gained acid clinker is extracted with water after cooling to be leached, and is neutralized with milk of lime, the filter residue heap after filtering is abandoned, lithium
More than 98% lithia is entered in solution with soluble sulfuric acid lithium salts in pyroxene, after evaporative concn, plus sodium carbonate liquor is heavy
Form sediment lithium carbonate, the attached production sodium sulphate of mother liquor.Between the lithium carbonate and filter residue that are finally given using above-mentioned PROCESS FOR TREATMENT spodumene
Yield ratio is 1:8 or so, more than 98% lithia becomes soluble lithium salt, still, becomes only less than 10% rubidium caesium
