For its extensive practical experience, 911 Metallurgist has a clear understanding of what successful mineral processing engineering is and how to go about achieving goal is the production of a material that is marketable and returns you and your investors sustainable revenues.

A couple years ago I recall reading that back in the early 2000''s there was enough gold in the central processing unit (CPU) and mathcoprocessors to make it worth while to recover it computer recycling firms to smelt the chips to recover the gold from the prongs and heat transfer points.

Of all the methods of extracting gold processing it from its ore, I used a few to evaluate two principal flowsheets in this case study. The flowsheets utilized operations that involved flotation, cyanidation and gravity concentration. Tests that mirror each of these unit operations were utilized to evaluate the principal flowsheets. This page offers a comparative review of gold recovery ...
