ore grinding lithium
Extracting Lithium
This table shows that lithium can be extracted from McDermitt A by direct acid leaching, but the required acid addition is large. The acid required to solubilize 89 pct of the lithium in this clay is equivalent to 1,125 pounds of 98-pct acid per ton of clay. In contrast, only 1 pct of the lithium in McDermitt B was acid soluble at 1 pH.

Ball mill grinding for 25 min (step B) and 35 min (step C) gave a very narrow range of P 80 values. Hematite-dominated ore types had significantly higher P 80 values after the primary grinding step A compared to the other ore types. Generally, Fe content increased in finer particle size classes while CaO and P contents decreased.

Extraction of Lithium from Lepidolite Using Mixed Grinding with
Mixed grinding with Na2S followed by water leaching was performed to extract Li from lepidolite. The leachability of Li increases dramatically in the ground mixture, regardless of the mixing ratio over the range of 1:1 to 3:1, while only 4.53% of Li was extracted in lepidolite ground without Na2S. The leachability increased with an increase …
