This process is more advantageous for copper-sulfur ores where the raw ore contains low sulfur, and the copper minerals easily float. Copper and sulfur minerals are first mixed and floated in a weakly alkaline slurry. The mixed concentrate is added with lime to separate copper and sulfur in a highly alkaline slurry. 3.
