Hi! I seem to be out of the loop at work. Too embarrass to ask my coworkers to explain it to me. Can anyone explain what nucleation and seeding is? Our process is basically a precipitation process where copper is precipitated by reacting Ca(OH)2 to Cu(OH)2. We have a sedimentation tank to separate the slurry from the filtrate. What I don't understand is how recirculation, pump sucks the slurry below and returns it to the calcium feeding tank, improve slurry formation. They mentioned nucleation and seeding enhancement. I don't get how "crystals" can form in a slurry or is a slurry considered a crystals?
