Practically impossible; the mean concentration of lead in sea waters is extremely low - 3.10-8 g/L.

Magnesium can be extracted from the minerals Dolomite (CaCO3·MgCO3) and Carnallite (KCl·MgCl2·6H2O), but is most often obtained from seawater
Seawater is dangerous to drink because it has a high concentration of salt, which can lead to dehydration. Consuming seawater can also disrupt the electrolyte balance in your body, causing further health complications.
Seawater is hypertonic to drinking water. This means that seawater has a higher concentration of solutes (such as salts) compared to drinking water. Drinking seawater can lead to dehydration as the body would need to excrete more water to get rid of the excess salts.
Sodium chloride (salt) is the most commonly extracted element from seawater. Other elements that can be extracted include magnesium, calcium, and potassium.
Gold has been extracted from seawater, but the cost is not worth the effort for the very small amount that can be obtained.
Halite (NaCl) is extracted by mining or from seawater by crystallization/recrystallization.
Sodium chloride is extracted from mines or seawater.
aluminium
Salt (sodium chloride, NaCl) is extracted from salt mines or seawater.
Bromine is mainly obtained from natural brine deposits, which are underground reservoirs containing high concentrations of salts. The brine is extracted and treated to remove impurities, after which bromine is extracted through evaporation and chemical processes. Another method is through seawater, where bromine is extracted by treating seawater to concentrate and purify the bromine content.
Three commercial products extracted from seawater are salt (sodium chloride), magnesium, and lithium. Salt is commonly used in food and industrial processes, magnesium is used in alloys and electronics, and lithium is used in batteries and pharmaceuticals.
lead
Galena is Lead sulfide. Lead comes from this.

Chlorine is extracted from seawater using a process called electrolysis, where an electric current is passed through the saltwater to split it into its components. Chlorine is collected at the anode during this process.
