welcome to the forum
as you may or may not have noticed, this forum is not really the place to discuss morphine extraction.
secondly, Im not sure your chemistry is correct there.. are you sure calcium morphinate even exists? calcium dimethyltryptaminate doesnt exist. If you add a base to a solution containing dmt (and this base is not calcium carbonate, rather usually sodium hydroxide, potassium hydroxide or sodium carbonate, or calcium hydroxide in 'dry teks'

what will precipitate is dmt freebase, and people recover using a non-polar solvent... search around the forum and the wiki and the FAQ and you'll learn a lot.
