galena is lead-sulfide (PbS; NOT lead). silica is nominally SiO2. I suspect that the amount of Si in any galena crystal as a substituent in the crystal structure is immeasurably small. the answer depends on your application, e.g. are you really tr...
Sand mining presents opportunities to extract rutile, ilmenite and zircon, which contain the industrially useful elements titanium and zirconium. These minerals typically are found in ordinary sand deposits and are separated by water elutriation. Sand mining is a direct cause of erosion, and impacts the local wildlife.
Purification processes vary according to the use intended for the silicon, from glass to hyperpure silicon used for solid-state devices in electronics. There are several ways to make silicon crystals from sand, but only one of them is for DIY chemists, which can be done at home. The other processes involve temperatures over 3632 degrees Fahrenheit.
