The present invention relates to a production method of lithium carbonate from lepidolite, more specifically a production method of lithium carbonate from lepidolite which comprises the following steps: a crushing step for crushing a lepidolite ore; a step for separating the crushed result to obtain a concentrate; a calcination step for changing the phase of the concentrate into a composition which is capable of water leaching by changing the chemical composition of the concentrate; a leaching step for leaching the calcined result using water; and a carbonization step for carbonizing lithium from the a leached extract.
