Solving Common Mineral Processing Service
Copper porphyry and skarn ore deposits can contain both primary copper minerals such as chalcopyrite and bornite as well as other secondary copper minerals. These minerals influence the chemical treatment strategies required to maximize recovery and concentrate grade.
Proper combination of Neo-Solutions’ mineral specific sulfide flotation reagents including frothers and collectors can improve froth flotation, leading to increased grade quality and/or recovery rates.
Most the secondary copper sulfide minerals, such as chalcocite, covellite, and digenite are typically associated with problematic gangue minerals.
These interfering gangue minerals may contain penalty elements such as:
- Arsenic
- Bismuth
- Cadmium
- Magnesium
- Calcium
- Aluminum
Even valuable metals such as lead and zinc derived from galena and sphalerite minerals can penalize the salable copper product.
Where gangue minerals and penalty elements are present, specialized Neo-Solutions proprietary modifier products are beneficial to remove and minimize impact of penalty elements. Modifiers include:
- Dispersants & Depressants
- Rheology Modifiers
- Activators & Promoters
