The diagram illustrates the process by which rock containing lead ore and other metals is transformed into pure lead.
Overall, the process consists of eight stages, beginning with the mining of the rock and ending with the casting of the lead. These stages can be broadly grouped into three main phases: raw material preparation, production, and finalization.
The process begins when the ores containing lead and other metals are mined. Following this, the raw ores are transported to the factory before being transferred to a crusher. Once this step is complete, the mixture undergoes a mixing process, during which water and pine oil are added to the mixture to remove impurities.
Afterward, the process continues with the filtering stage. The next step involves refining at 1400 degrees to remove waste gas before the products are separated. After being separated, the products are then moved to the casting stage. The sequence concludes when the finished products are sold on the market, marking the end of the process.
