2. Caustic soda use in a lead refinery The classical refinement of raw lead is given in Fig. 1, showing the considerable use of caustic soda. First, the copper is removed from the raw lead, then the arsenic and antimony are removed by the so-called `softening' process. The lead softening is carried 0304-386X/97/$17.00 1997 Elsevier Science B.V.

Fire refining mainly includes melting, copper removal (including melting-out for copper removal and sulfur-adding for copper removal), oxidation refining and alkaline refining for arsenic, antimony and tellurium removal, zinc-adding for silver removal, chlorination for zinc and lead removal, final refining, and ingot casting (Fig. 1). The ...

Copper electro-refining (Cu-ER) is the principal method for producing >70% of high or 99.97% pure copper cathodes from 97-99% pure blister/fire refined-scrap copper anodes. While the inert and most of less soluble impurities settle as anode slime/sludge, other soluble impurities, particularly the metalloids (group VA/15 elements or Q: As, Sb and Bi) …

Increasing the use of steel scrap and enhancing its recycling utilization are important strategies for fostering the low-carbon and environmental-friendly growth of the iron and steel industry in China.
