<p>CRYSTALLIZATION APPARATUS AND PROCESS A crystallization apparatus and process especially useful for the continuous regeneration of metal processing solutions, such as copper etchants, where direct recovery of metal values in the form of large crystals of high solids content is achieved and fouling of heat exchange surfaces is obviated by a scouring action obtained through addition of preformed crystals to the heat exchange zone. -i-</p> |
