Copper Segregation Process - 911 Metallurgist

2020-5-7  The copper segregation process, which was discovered in 1923, comprises heating copper ore with a reducing agent and sodium chloride to about 750° C., followed by flotation of the metallic copper produced. By 1931 the process was sufficiently developed so that two plants were constructed in Africa for treating oxidized ores.

The column is, however, a good separator of bubbles from the feed slurry, especially if wash water is added.
