Title:
METHOD FOR JUDGING PROGRESS OF OXIDATION REACTION
Document Type and Number:
Japanese Patent JPH06306500
Kind Code:
A
Abstract:
PURPOSE: To rapidly and conveniently judge the progress of an oxidation reaction at the time of recovering noble metal from noble lead.
CONSTITUTION: The m.p. of a sampled metal is measured, and the noble metal content of the sampled metal is obtained from the measured m.p. and the relation between the previously obtained m.p. of the metal and the noble metal grade in the metal, and the progress of the oxidation reaction is judged therefrom. The end point of the oxidation and refining reaction is extremely easily and rapidly obtained in this way.
