The diagram illustrates the process of metal production for the building industry. Overall, there are eight stages in this process, beginning with the mining of ore and culminating in the casting of the final shape.
Initially, the rock that contains lead and other metals is drilled using specialized machines at the mining site. This extracted metal is then loaded onto delivery trucks for transportation to the factory. At the factory, the rocks are crushed into smaller particles with the assistance of water.
Next, water is introduced into a mixing tank to create a lead mixture. Subsequently, the lead mixture undergoes a filtering stage, during which it is combined with pine oil and refined by heating to 1400 degrees Celsius. Waste gas produced during this process is properly disposed of.
Afterward, in a kettle, the melted lead and other metals are separated. Finally, the last step involves casting, where the melted lead is shaped into its final form.
