Abstract
The experimental studies on the basis of theoretical informations have been carried out for the removal of trace oxygen and sulfur in liquid copper.
Analytical values of oxygen in copper were compared with those calculated from emf values of a zirconia solid electrolyte galvanic cell. The oxygen in copper could be removed to around 1 mass ppm by either hydrogen gas or carbon reduction.
The sulfur in copper could be removed to less than 0.05 mass ppm by adding oxygen and exhausting as SO2 gas.
This method was proved to be a simple and efficient pyro-metallurgical process for the removal of trace gas elements in liquid copper.
