Mining Frother Chemistry
During the last decade, Nalco Water has led the development of frothing reagent technology that incorporates new understandings of the hydrodynamic elements of flotation circuits. Using the concept that each frother has a unique hydrodynamic curve and specific critical coalescence concentration that is dependent on air rate, we developed a new frother optimization methodology along with a simplified set of frothers that are separated into two distinct families: Alcohol and polyglycols. These two families each contain five unique frothers that can handle all the needs required in flotation circuits.
When you partner with Nalco Water, your mining operation benefits from our expertise and our experience. We are dedicated to helping you meet your recovery and grade targets so you can improve efficiency and meet your mining KPIs.
Flotation 360™
Mineral processing optimization can feel like a moving target. Changing ore, an incorrect formulation or failing to balance recovery and grade can impact your bottom line. But Nalco Water has your solution: Flotation 360. This digital technology helps you maximize productivity and optimize your flotation circuit performance.
Optimize your circuit with the predictive capabilities of Flotation 360
- Improve performance to increase recovery and profitability
- Enhance visibility of potential impacts of future ore changes, allowing for mitigation of any challenges in advance
- Optimize reagent dosing and chemical consumption, improving the total cost of operations
- Reduce maintenance challenges such as float cell valve failures, and spend less time manually troubleshooting
Nalco Water Frother Chemistry
The NALFLOTE 500 Series, weak frothers are suitable for circuits that cannot tolerate persistency or a thick froth. They promote faster kinetics, create a stable froth that breaks down easily in launders, and exhibit good activity over a wide pH range. Typically, they are well suited to replace MIBC on circuits.
- Promote faster kinetics.
- Produce smaller bubbles than other alcohol-type frothers, resulting in increased mineral recovery.
- Exhibit good activity over a wide pH range.
- Create a stable froth that breaks down easily in launders.

The NALFLOTE 600 Series, weak frothers exhibit low persistency. They promote faster kinetics and bubble strength, exhibit good activity over a wide pH range, and create a stable froth that breaks down easily in launders. The frothers produce bubble sizes that improve aeration and gas holdup. These frother help to improve recovery in a cost-effective manner and are suitable replacements for MIBC.
- Promote faster kinetics.
- Produce smaller bubbles than other alcohol-type frothers, resulting in increased mineral recovery.
- Exhibit good activity over a wide pH range.
- Create a stable froth that breaks down easily in launders.

The NALFLOTE 600 Series of moderate frothers increases recovery by producing smaller bubbles than other alcohol-type frothers to improve aeration (bubble size distribution instead of aeration), which positively impacts the concentration grade. These frothers help to enhance faster kinetics and gas hold up in the flotation of desired metallic and non-metallic ores, while exhibiting good activity over a wide pH range.
- Promotes faster kinetics.
- Low toxicity.
- Produces smaller bubbles resulting in increased mineral recovery.
- Exhibits good activity over a wide pH range.

The NALFLOTE 700 Series of strong frothers is well suited for column cells with longer residence time where a stronger lift is required. It has fast kinetics and persistency and is especially suited to capturing coarse and middling particles from the gangue. They are suitable for circuits with conventional and column cells that require fast kinetics and enough persistence to hold the load and still provide good froth mobility. They exhibit good activity over a wide pH range and create a stable froth.
- Provides a strong load support for coarse and middling particles.
- Promotes faster kinetics and persistence.
- Exhibits good activity over a wide pH range.
- Creates a stable froth that breaks down easily in launders.

Frothers Success Stories
Nalco Water Frother Program Helps Copper Concentrator Increase Recovery and Reduce Total Cost of Operations
A copper mine in South America partnered with Nalco Water to help achieve their operational goals. The goals included improving recovery through their copper flotation circuit, increasing productivity, and ultimately reducing the total cost of operations while ensuring a safe production environment. By introducing FrothPro 507, a specific product in our diverse portfolio of frothers, Nalco Water helped the mine save on maintenance and increase recovery by 2,526 tons per year, amounting to $14.98M in value delivered to the customer.

Nalco Water Froth Flotation Solution Helps Increase Recovery at a Copper and Moly Operation
A copper mine in the southwestern United States was challenged with processing a more difficult type of ore with daily variability. The customer approached Nalco Water for help with determining a treatment program that would help improve the recovery for both copper and moly. By implementing the right froth flotation program, Nalco Water was able to help improve overall recovery by 2% at the same dose as the incumbent product. The improved recovery ultimately helped to reduce the total cost of operations. Download the case study below to learn more.
