摘要： A method for enriching lithium from a lithium clay includes the following steps (1) the raw ore were crushed to produce fine particles, (2) performing rougher on the fine particles by adding ferric sulfate or ferric nitrate, sodium oleate, and cocoamine to obtain rough concentrate and rough tailing, (3) finely separating the rough concentrate to obtain the first part of concentrate, (4) re-grinding the rough tailing by ball mill, (5) performing rougher on the reground tailing to obtain reground rough concentrate and re-ground rough tailing, (6) performing cleaner on the reground rough concentrate to obtain the second part of concentrate, and (7) performing scavenger on the reground rough tailing to obtain the cleaned tailing.
