- Crush and grind the ore to a fine powder.
- Make a slurry of powder and water.
- Add collector (e.g., ethyl xanthate), frothing agent (pine/eucalyptus oil), and activators/depressants.
- Agitate with air so ore particles attach to bubbles and form froth.
- Skim, wash, and collect the froth; this is the concentrated copper pyrites.
