摘要 |
<p>When agglomerating ore concentrates the green agglomerated bodies lack strength and hardness to be handled and charged into the reducing furnaces. The process according to the present invention resides in the hardening of the green agglomerated bodies by exposing them to a high frequency alternating field and in a further hardening treatment by exposing the bodies so treated to a hydrothermal treatment at a high temperature and at a corresponding high pressure.</p> |
