    Although most zinc is derived from ore containing the zinc sulphide mineral sphalerite, there are also occurrences characterized by non-sulphide minerals, such as zinc-oxide, zinc-carbonate and zinc-silicate. These oxides are susceptible to attack by dilute sulphuric acid, which releases the zinc into solution, along with numerous other elements.
