The International Lead Zinc Research Organization, Inc. was formed in 1958 as a non-profit research foundation. Silver was added to its core group of research metals in 2002 with the launching of the Silver Research Consortium.

ILZRO's sponsors include most of the major producers of lead, zinc and silver, and significant numbers of end-users of these metals from among the steel, automotive, die casting, battery, galvanizing and other industries.

ILZRO's R&D portfolio for 2007 encompases the primary applications of lead, zinc and silver, as well as significant work in the areas of the environment and human health. The results of ILZRO R&D efforts are communicated through a variety of forums, including research reports, technical seminars, expert consulting, internet sites and printed publications.
