Zinc comes from natural mineral deposits of ore in the earth s crust. The deposits may be close to the surface, in which case they will be mined from an open pit. Alternatively, they may be some distance underground and cannot be mined directly from the surface.
Answer 1: The elements come from one of three sources. The first source was the BIG BANG that created the Universe 14 billion years ago. When the big bang occurred, the elementary particles initially were too hot initially to make any stable atoms... but after a few thousand years, when things cooled down a lot, Hydrogen and Helium got made. The ratio was about 1 He for every 4 H atoms. This is called PRIMORDIAL NUCLEOSYNTHESIS. Then for elements from He to Fe: these elements are made on the interior of BIG stars (bigger than sun).
