Web16 nov. 2015 · 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 … Webin plant residue for various periods of time based on the carbon to nitrogen ratio (C:N) of the crop species grown. Cover crop species with a low C:N ratio ( below 20:1) will release nutrients faster than a cover crop with a high C:N ratio (above 40:1). Cover crop mixes that include legumes will fix and add nitrogen to prevented plant acres.
