copper ore froth

Copper mining. From ore to copper.

Concentrating the ore: The ore is crushed, ground and then enriched (concentrated) by Froth Flotation. The powdered ore is mixed with a special paraffin oil which makes the copper mineral particles water repellent. It is then fed into a bath of water containing a foaming agent which produces a …

The froth is then dried to recover the mineral particles. The importance of froth flotation process is that, it is easy to separate two sulphide ores present in a mixture (by adjusting the oilwater proportion or by using depressants). Also this process is significant because it allows for the economic extraction of metals from lower grade ores.

Barbian et al. (2005) developed a froth stability column to be used at industrial scale, allowing froth stability to be correlated to flotation performance. The results, from a copper sulphide ore, showed that the highest dynamic froth stability resulted in the highest copper grade but lowest recovery.
