Stage 2: 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 kind of bubble bath. This is a rare chance to see a mill and flotation building before the roof is built.

Flotation Froth - an overview ScienceDirect Topics. The froth flotation technique was originally developed in about 1910 to raise the copper concentrations of the strip-mined ores of Bingham Canyon near Salt Lake City 9 and was further perfected for the differential separation of lead zinc and iron sulfides at Trail B.C. at about the same time 10 .
Use of humic substances in froth flotation processes
Film flotation tests showed that biosolids and HAs can be used as environmental-friendly collectors in froth flotation processes since they modify the copper sulfide ore hydrophobicity. The ability to form and stabilize foams of biosolids and HAs are evaluated by the Bikerman test Reyes-Bozo et al. 2011a Reyes-Bozo et al. 2011b .
pine oil is used in froth flotation ? - Brainly.in
Ans. Froth flotation is a process to purify sulphide ores in presence of pine oil. The oil acts as hydrophobic agent and forms froth with hydrophobic impurities which is skimmed off from the surface leaving behind the concentrated mineral.
The processing techniques depend on the nature of the ore. If the ore is primarily sulfide copper minerals such as chalcopyrite the ore is crushed and ground to liberate the valuable minerals from the waste & 39;gangue& 39; minerals. It is then concentrated using mineral flotation.
