1. A method of increasing an amount of zeolite contained in a zeolite-containing material, the method comprising: providing a sample of a zeolite-containing material having at least one rare earth element therein; increasing the amount of zeolite in the sample of the zeolite-containing material by reacting the sample of the zeolite-containing material with an extracting agent that extracts at least a portion of the at least one rare earth element from the sample of the zeolite-containing material; separating the reacted sample, from which has been extracted at least some of the at least one rare earth element previously associated therewith, from the extracting agent; and obtaining the reacted sample in which the percentage increase in the amount of zeolite in the reacted sample is between 22% and 146%, as measured via x-ray diffraction.
