    This can be a very complicated answer to a very complicated
    question.  If you are planning to do dyeing at the commercial level,
    there are many proprietary procedures used by various companies.  I
    understand there are a number of books available that provide 
    information on the subject but will have to depend on others in this
    regard.  You might do a search of the Lapidary Journal
    archives...John Sinkankas wrote a number of articles for LJ in 1963
    and the book The Agates of North America contains some useful
    information. 

    If, however, you are planning on doing a bit of dyeing on a small
    scale, look for a great little book "Gemstone and Chemicals" aka "How
    to create color and Inclusions" by the late George W. Fischer, Ph.D
    dated 1991.  Mr. Fischer was a chemist  who spent about 25 years
    researching how to color agates and jaspers using inorganic
    substances.  I have used many of his formulations and found they
    really work!  The problem you face is that there are a very limited
    number of these books available. 

    Good luck and cheers from Don at the Charles Belle Studio in SOFL
