鉛 可以这样說,近年来鉛冶煉工业是沿着扩大所用設备的規模、提高其生产能力及改善生产过程中某些工序的方向发展的,而不是改变生产过程本身的原理。在极大部分冶煉厂中,鉛精鑛的燒結焙燒、燒結块的鼓风爐熔煉和各种不同方法的粗鉛精煉,仍然是提取鉛的技术操作流程。在提取鉛的技术操作过程的各个阶段中,正在做許多工作来提高生产的机械化程度,实施和推广自动控制和管理生产过程的各种方法。
Lead can be said that in recent years the lead smelting industry has been moving in the direction of expanding the scale of equipment used, increasing its production capacity and improving certain processes in the production process, rather than changing the principle of the production process itself. In most smelters, the roasting of lead concentrates, the blast furnace smelting of sinter blocks, and the various methods of crude lead refining are still the technological processes for the extraction of lead. Much work is being done to improve the mechanization of production and to implement and promote various methods of automatic control and management of the production process in all phases of the technical operation of lead extraction.
