The lepidolite concentrate is manually sent from the concentrate warehouse to the scale plate conveyor belt by forklift or grab bucket, and then transported by metering belt to the two-axis mixing and the sulfate used with it for mixing in the first phase. The proportioned mixture is stirred by the agitator and enters the rotary kiln for calcining. The PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC magnetic is removed after the crystal transformation at about 800℃~900℃ in the calcination section.
After cooling in the cooling section, the baking material is discharged from the kiln head, so that the Li2O and SO42- in it are combined into Li2SO4 soluble in water, and acidified clinker is obtained. After cooling to about 60℃ by the cooling machine, the large pieces are broken by jaw crushing and sent to the buffer storage bin for caching. The metering device under the storage bin and the new water before the mill are mixed in proportion and then enter the mill for water quenching and grinding, grinding to about 100 mesh, the slurry naturally flows into the mixing tank for re-mixing, PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC magnetic iron removal.
The clinker is cooled and pulped so that the soluble lithium sulfate in the clinker is dissolved into the liquid phase. In order to reduce the corrosion of the solution to the leaching equipment, the residual acid in the clinker is neutralized with limestone slurry, and the pH value is adjusted to 6.5 ~ 7.0. At the same time, PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC is used to remove most of the impurities such as iron and aluminum, the leaching liquid to solid ratio is about 2.5, and the leaching time is about 0.5h. The leached slurry was filtered and separated to obtain the leached liquid, which contained about 100g/L Li2SO4 (Li2O 27g/L), and the filter cake was the leached residue, with a moisture content of about 35%. In order to reduce the loss of lithium, the leaching residue is washed by reverse agitation, and the lotion is returned to the slurry for leaching.
