现有炼铅工艺的缺点和不完善,已普遍引起人们对创立新的、更有效的流程,即对物料不经烧结焙烧而直接熔炼的流程感兴趣。选择某种冶炼工艺,首先取决于所处理物料的成分。用空气或富氧鼓风的反应熔炼过程,仅适 The shortcomings and imperfections of existing lead smelting processes have generally caused interest in creating new, more efficient processes, ie, processes for direct smelting of materials without sintering and roasting. The choice of a smelting process depends first and foremost on the composition of the material being processed. Use air or oxygen-rich blast reaction melting process, only suitable
