Extraction of Lithium from Lepidolite Using Mixed Grinding ...

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 of the grinding time, and ultimately, 93% of the Li ...

How to Make Eggshell Calcium (and Why You'd Want to)

Feb 25, 2018  “Calcium carbonate in the egg + acetic acid in vinegar = CaCO3 + 2CH3COOH → Ca(CH3COO)2 + H2O + CO2 So you’d get water, carbon dioxide, and calcium acetate, a water soluble salt. May want to let evaporate, to remove any remaining vinegar, and then add your own water. Calcium acetate is a food additive; dosage is important, of course.”
