arsenic antimony elimination - bazantlubin.pl

The elimination of arsenic, antimony and bismuth in the preceding operations has, unless the materials under treatment are uncommonly impure, left only small amounts of these metals in the blistercopper. Their elimination during the refining operation probably takes place entirely by scorification.

The rate of arsenic and antimony elimination from molten ...

The rate of As elimination from molten copper by the use of Na2CO3 slag was measured at 1523 K. The results obtained under the present experimental conditions show that As in molten copper is eliminated in a penta-valent form and that its elimination rate increases with increasing initial oxygen concentration in molten copper. Based on the results obtained in the present study, the overall ...

How to Remove Arsenic, Antimony Bismuth from Copper

2017-2-6  The elimination of arsenic and antimony in this operation is considerably greater than that of bismuth. In the case of slags produced from blast-furnace practice, smelting similar materials, I have never found more than 0.015 per cent, of arsenic, and only traces of antimony. It is, therefore, probable that the elimination

Bismuth, Arsenic and Antimony Removal From Anode

2013-7-18  In 40–60 min of treatment, bismuth elimination was in the range from 41 to 88% and arsenic elimination was in the range from 2 to 25%. Antimony removal rates were found to be negligible, due to a combination of the effects of a low antimony activity coefficient and the low vapour pressure of pure antimony.
