Test results are presented for two dry processing methods of high tension/electrostatic separation and pneumatic tabling, as well as two wet methods of gravity tabling and froth flotation. Each wet mineral separation method yielded two clean products following a limited number of cleaning and scavenging operations; one product graded 95 to 98% C, the other, 97 to 99% bath.

2019-4-15  A novel process consisting of pyrolysis and physical separation was proposed to comprehensively recycle spent lithium ions batteries. The discharging of spent lithium-ion batteries (LIBs) can be achieved by soaking in 5% NaCl solution. Approximately 99.91% of organic electrolytes in spent LIBs were recovered by low-temperature volatilization.
