The invention discloses a method for directly extracting lithium from a lithium porcelain stone raw material. Lithium porcelain stone serves as the raw material, and the method includes pretreatment of the lithium porcelain stone. The method includes the following steps that firstly, the raw material is broken; secondly, a roasting mixing material is prepared; thirdly, the prepared roasting material is roasted; fourthly, a roasting breaking material is prepared; fifthly, water leaching is conducted; sixthly, solid-liquid separation is conducted; seventhly, washing is conducted; and eighthly, lithium or lithium salt is prepared. By means of the technology method for directly extracting lithium from the lithium porcelain stone, the method technology is simple and reliable, the production cost is low, and in addition, the lithium recovery rate is high; and industrial production is better achieved.
