A method for extracting lithium from lithium-containing material including reducing the material to base particle size; mixing the base particles with an aqueous solution of a first base; heating the slurry to a temperature in a range of 60 to 75 C. for 0.5 to four hours; adding hydrochloric acid to the heated slurry until it reaches a pH level of 1.0 to 0.00; maintaining the acid-treated slurry at 60 to 75 C. for 0.5 to four hours; cooling the acid-treated slurry to near-ambient temperature and treating it with a second base until the acid-treated slurry reaches a pH of 7.5; precipitating deleterious base metals from the direct lithium extracted solution and combining the deleterious base metals with the leached clay solids; and passing the direct lithium extracted solution and solid tailings materials through a filter.

The present invention relates to a method for processing acetic acid solvent in an oxidising unit of a PTA industrial apparatus; said method uses a pressure filter machine to filter crude terephthalic acid slurry, and then, using a multi-stage counter-current method, uses washing water to wash the acetic acid solvent, and, by means of setting up a bias-current and drainage, prevents residual liquid in the filtrate pipe from entering the next area following the rotation of the pressure filter machine, improving washing efficiency and reducing the amount of washing water; the present invention integrates the processes of filtering and washing crude terephthalic acid into a single pressure filter machine, such that the process is shorter, the occupied floor space is reduced, and energy consumption is lower. A method feeding nitrogen gas into the mother liquor tank and washing liquid tank is used to regulate the pressure balance of the system.
