PLINT process

PLACID/PLINT process [13,14], The PLACID process (see also Chapter 16) is based on the electrowinning of lead from a chloride solution in a cell where the cathode and anode are separated by a semipermeable membrane. Lead oxide and lead dioxide are converted to soluble lead chloride, whilst lead sulfate is converted in a hot brine circuit. The sulfate ion is removed as gypsum after the addition of lime. The FLINT process is an advanced adaptation of the PLACID process and operates in parallel with a pyrometallurgical route that smelts the metallic lead fractions from the battery. [Pg.503]

Lead dissolution efBciency is very high. In a PLACID-/ o or PLINT-/ o combined process, the overall measured extraction rate was 99.5%, because the leaching process extracted the available lead from slags and other products already rejected by the furnace operation. [Pg.794]
