The image illustrates an 8-step process: 1. Mining the rock, where rock containing lead and other metals is extracted from a mine with a straightedge shaft and loaded onto trucks. 2. Transporting the rock to a factory via truck. 3. Crushing the rock with the addition of water. 4. Mixing the crushed material with water in a tank to create a lead mix. 5. Filtering the mix with the addition of pine oil. 6. Refining the filtered substance by heating it to 1400°C, producing waste gas and melted lead and other metals. 7. Separating the melted lead from other metals, which are categorized as waste. 8. Casting the lead from a kettle into an ingot.

The process illustrates how lead is produced.
Overall, it is notable that there are 8 primary stages in the manufacturing process, beginning with rock exploitation, and ending with the formation of final products.
After mining rock, which contains lead and other metals, it is transported by lorries to a plant to continue processing. In the following stage, the rock undergoes the crushing stage with water to create smaller pieces. Afterwards, these pieces are combined with oil and water in a container to become a mixture.
In the fifth stage, the mixture flows through a long pipe to reach a filter where unwanted substances are eliminated. The remaining lead and other metals are then heated to a remarkably high temperature of 1,400 degree Celsius, creating melted lead, other metals and waste gas. After that, while other metals are removed, the melted lead is selected to be cast into final products, which are ready for other purposes.
