pH Modifiers for Mineral Processing and Flotation

Optimize Mineral Conditioning and Flotation Performance

Effective pH control does more than adjust the acidity or alkalinity of a flotation circuit. It can influence mineral surface charge, reagent interactions, dissolved ions, and the selectivity of collectors for valuable minerals versus unwanted gangue.

Arkema's Custo pH^® technologies are designed to help create optimal conditions for mineral separation by:

• Improving mineral surface conditioning
• Supporting effective collector performance
• Managing soluble divalent ions
• Reducing the impact of process water quality
• Improving gangue selectivity
• Supporting efficient reagent use

By controlling these interactions, Custo pH^® modifiers can help optimize flotation conditions and overall metallurgical performance.

Custo pH^® Modifiers

Arkema's Custo pH^® line of customized pH modifiers is designed to improve flotation efficiency by optimizing mineral surface conditions and supporting selective collector adsorption.

Depending on the mineral and process conditions, Custo pH^® technologies can help sequester soluble divalent ions that may interfere with collector performance and increase reagent consumption. Proprietary surfactant technologies can also help prepare mineral surfaces for more effective collector interaction.

Our technical experts evaluate ore mineralogy, water quality, flotation chemistry, and operating conditions to identify the appropriate pH modification strategy for each application.
