Abstract:
The present disclosure relates generally to systems and methods for purifying and recycling the lead content from lead-acid batteries. A system (40) includes a reactor (56) that receives and mixes a lead-bearing material (54), a carboxylate source (58), and a recycled liquid component (60) to form a leaching mixture (62) wherein a phase separation device (64) isolates a lead salt precipitate (66) from a liquid component (68) of the leaching mixture (62). The system further includes a closed-loop liquid recycling system coupled to the phase separation device and to the reactor, wherein the closed-loop liquid recycling system receives the liquid component isolated by the phase separation device and recycles a substantial portion of the received liquid component back to the reactor as the recycled liquid component. The closed-loop recycling system optionally comprises a purification device (76), especially configured to remove sulfates from the liquid component without substantially removing dissolved lead salt.

Abstract:
In the heat treatment of fine-grained mineral solids, in particular for calcining clay or gypsum, the solids are passed through a flash reactor (5), in which they are contacted with hot gases at a temperature of 450 to 1500°C, and subsequently they are passed through a residence time reactor (7) at a temperature of 550 to 800°C, from which they are withdrawn after a residence time of 1 to 600 minutes and possibly supplied to a further treatment stage.
Abstract:
An optical network (10) comprising an optical network element (12) comprising a first optical transmitter (14), a first controller (16), an optical receiver (18), a second optical transmitter (22), a second controller (24) and optical receiver apparatus (26). Said first controller is arranged to control said first optical transmitter to generate and transmit a first optical signal in response no second optical signal being detected. Said first controller is arranged to iteratively generate and transmit said first optical signal at different wavelengths of a plurality of wavelengths until said second optical signal is detected, and is further arranged to subsequently maintain generation and transmission of said first optical signal at said wavelength at which said second optical signal is detected. Said second controller is arranged to control said second optical transmitter to generate and transmit said second optical signal following detection of said first optical signal by said optical receiver apparatus.

The present disclosure relates to systems and methods by which lead from spent lead-acid batteries may be extracted, purified, and used in the production of new lead-acid batteries. Such a system may include a first phase separation device (76) configured to receive the first mixture from the basic lead stream digestion device (192), isolate a liquid component (196) from one or more insoluble components (78) of the first mixture, and output the liquid component (196). The system also includes a lead salt precipitation device (200) configured to receive and mix the liquid component and a carboxylate source (201) to form a second mixture including a lead salt precipitate and output the second mixture. The system further includes a second phase separation device (92) configured to receive the second mixture from the lead salt precipitation device (200), isolate the liquid component (96) from the lead salt precipitate (94) of the second mixture, and output the lead salt precipitate, which may later be converted into leady oxide particles (100).
