   All the common ore-forming elements are present in magmas and ordinary rocks, in amounts ranging from a few parts per billion to several thousands of parts per million. Selective concentration of one or more ore constituents to form a mineral deposit is achieved by some combination of the following:Read more

   All the common ore-forming elements are present in magmas and ordinary

   rocks, in amounts ranging from a few parts per billion to several thousands of

   parts per million. Selective concentration of one or more ore constituents to

   form a mineral deposit is achieved by some combination of the following:

   1. extraction of the constituents from magmas, rocks, and oceans;
   2. transport of the constituents in a fluid medium from the source region to the site of deposition.
   3. localization of the constituents at certain favorable sites.

   The ore-forming processes may be grouped into the following four broad

   categories:

   1. Orthomagmatic processes
   2. Sedimentary processes
   3. Metamorphic processes
   4. Hydrothermal processes
