摘要： A microporous lead-containing solid material is produced, which can serve as a carrier for desired materials into a reaction for various desired purposes. For example, if the microporous solid is impregnated with borax it tends to inhibit the growth of unduly large crystals of tetrabasic lead, which is useful in producing batteries having improved functional qualities.

摘要： A solid state reaction method for the production of tetrabasic lead sulfate includes the steps of mixing a stoichiometric mixture of 3PbO.PbSO4.H2O and PbO and heating the stoichiometric mixture of 3PbO.PbSO4.H2O and PbO at a temperature between 500 and 700° C. for 3 to 8 hours. The method also includes the steps of deagglomerating and sieving resulting tetrabasic lead sulfate.

摘要： Recovery of lead values from lead-bearing material, by leaching the said material at ambient temperature for a period not exceeding 1 hour with a mixture of ammonium sulfate and aqueous ammonia to produce a supersaturated solution, separating undissolved substances, treating the resultant solution at a temperature higher than that at which the leaching operation was effected without substantial loss of ammonia, to cause precipitation of a major portion of the lead content from the said solution, and separating the precipitated solids.

摘要： A method of pretreatment and bromine recovery of PCB Incineration ash is disclosed that relates to the field of comprehensive recovery of valuable metals by full wet method, especially relates to a method of valuable metals and bromine recovery, precious metals enrichment in pretreatment process of PCB Incineration ash. The major steps includes alkali leaching, Cu extraction back-extraction, neutralization-precipitation to separate, Bromine evaporative crystallization, regeneration, acid pickling, Zn evaporative crystallization, removal of Zn and Cu. Compared with the traditional comprehensive recovery process of ash, the invention can separate bromine from ash and recover valuable metals such as copper, zinc and lead with the maximum extent, at the same time, the enrichment of silver and other precious metals is beneficial to the subsequent recovery of precious metals. It has high added recovery value and no tailless discharge.
