The provided diagrams illustrate the step-by-step procedure involved in the production of lead. Ranging from mining the rock to casting.
Overall, it is a man-made, linear sequence consisting of 8 distinct stages, which is predominantly automated. The workflow initiates with the preparation of raw materials and concludes with the disposal of the final product.
Initially, the rock after mining is placed into the truck to be transported to the factory. Following this, the rock is crushed before being transferred to a specialised mixing tank. Once this step is complete, crushed rock undergoes a mixing phase, during which pine oil and water are added to the mixture.
Afterwards, the process continues with the filtering process. The next step involves refining at 1400 degrees to melt lead and other metals, which is followed by the separating phase of the products. After being separated other metals out of the mixture, the products are then moved to the casting phase. The sequence concludes when the lead is cast and shaped, then used to serve various purposes in daily life, marking the end of the process.
