Lithium extraction from clay-type lithium resource using ferric sulfate
Clay-type lithium resources have been developed as an important natural lithium source secondary to hard rock sources and brine sources. In this study, a green and effective lithium extraction process employing ferric salt solutions to leach lithium-rich clay was proposed. Upon calcination treatment, 73.6% of lithium could be leached over a period of 180 min using a …

Help with HCl and Bleach
It is not needed. It suggests much higher amounts of H 2 O 2 when starting the AP process. Only a capful is needed. We now understand more about how the HCl and bleach process works. There is no stoichiometric amount because no matter how you add the bleach there are going to be losses as chlorine gasses off and you always want excess HCl.

Animal fats and cold-pressed vegetable oils hardly need bleaching but when vegetable oils started to be produced by solvent extraction, the resulting oils were too dark to sell as such. That also holds for palm oil. Bleaching these oils with bleaching clay solved their color problems but led to the problem of spent earth disposal.
