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.

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
Una mina de cobre en América del Sur se asoció con Nalco Water para poder lograr sus objetivos operativos. Los objetivos incluían la mejora de la recuperación a través de su circuito de flotación de cobre, el aumento de la productividad y, en última instancia, la reducción del costo total de las operaciones al mismo tiempo que se garantiza un entorno de producción seguro. Al utilizar FrothPro 507, un producto específico dentro de nuestra diversa cartera de espumadores, Nalco Water ayudó a la mina a ahorrar en mantenimiento y aumentar la recuperación 2,526 toneladas al año, alcanzando los $14.98 millones en valor para el cliente. Descargue el estudio del caso a continuación para obtener más información.
La solución de flotación por espuma de Nalco Water ayuda a aumentar la recuperación en una planta de cobre y molibdeno
Una mina de cobre en el sudoeste de los Estados Unidos enfrentaba una complicación con un procesamiento de un tipo más difícil de mineral con una variable diaria. El cliente recurrió a Nalco Water para determinar un programa de tratamiento que mejoraría la recuperación del cobre y el molibdeno. Al implementar el programa de flotación por espuma adecuado, Nalco Water pudo ayudar a mejorar la recuperación general un 2 % con la misma dosis que el producto utilizado en ese momento. En última instancia, la recuperación mejorada ayudó a reducir el costo total de las operaciones. Descargue el estudio del caso a continuación para obtener más información.
