Lead soil
Lead can be considered as one of the most widely used metals in industry, for the supply of which various mines have been discovered and exploited throughout the country. Most of the lead extracted from the mine consists of rocks that are a combination of zinc and lead. Depending on the facilities of the mine, the extracted rocks may be crushed in the same place and turned into soil, or this process can be done at the delivery site for concentrating.
Soil zinc
The first step in preparing zinc metal is to use zinc soil. In general, 80% of zinc mines are underground, 8% are open pit and the rest are a combination of the two. In Iran, most of the exploitation and production of zinc is done from underground mines.
In general, the grade and value of the soil obtained from the exploitation of a mine depends on the amount of impurities in it, so that the lower the amount of impurities, the higher the rial value of the soil.
