The invention relates a continuous separating and recycling method and system for oil sand ore containing rich carbonate. Pitch oil resources, such as oil sand, oil shale and oily sludge, containing carbonate mineral substances are mixed with a prepared solution and a chemical additive under certain conditions, a reaction occurs, mineral substances in pitchblende are dissolved, and thus the purpose of separating pitch oil and mineral particles is achieved; the separated pitch oil is subjected to subsequent processing to further remove carried moisture and solid particles, and a clean pitch oil product is obtained; waste liquid and mineral substance precipitate which are generated in the process are recycled and treated respectively, and finally harmless emission is achieved. In this way, pitch oil is effectively extracted out of ore, energy resources are greatly saved, and the purposes of energy-saving and emission-reducing production of pitch oil normal-temperature extracting or recycling are achieved.
