The invention discloses a preparation and recovery system for calcium carbonate material. The preparation and recovery system comprises a calcium carbonate slurry container, a calcium carbonate treating device, a calcium carbonate sedimentation tank, a pre-slurry-treatment pipeline, a post-slurry-treatment pipeline, a finished-product pipeline, a clear-liquid pipeline, a recovery pipeline and a recovery pipeline valve device, wherein the calcium carbonate slurry container and the calcium carbonate treating device are communicated through the pre-slurry-treatment pipeline; the calcium carbonatetreating device and the calcium carbonate sedimentation tank are communicated through the post-slurry-treatment pipeline; the calcium carbonate sedimentation tank and the calcium carbonate slurry container are communicated with each other through a recovery pipeline; the recovery pipeline valve device is installed on the recovery pipeline; the calcium carbonate treating device is connected with one end of the finished product pipeline; and the calcium carbonate sedimentation tank is communicated with one end of the clear-liquid pipeline. The system can recover residual slurry obtained after treatment while producing a finished calcium carbonate powder product, so materials are saved and the demands for energy conservation and emission reduction are met.
