In many cases, the traditional commodity means of altering pH and the application of old chemistries do not provide the selectivity required to achieve modern mineral grade requirements. Commodity-type pH modifiers no longer deliver the best cost performance. A custom-formulated pH modifier is needed to provide better froth structure and gangue selectivity for an improved grade and to create ideal conditions for increased recovery during mineral processing.

Arkema’s Custo pH® line of tailor-made pH modifiers increases the efficiency of the flotation process by facilitating optimum zeta potential and creating ideal conditions for collector function and mineral separation. They provide better pH control sequester soluble divalent ions, which could potentially increase flotation collector usage, decrease collector efficiency, and reduce the negative impact of water quality on reagent consumption. Our proprietary surfactants clean and prepare the mineral surface for efficient collector performance. Our pH modifiers selectively inhibit the interaction of gangue minerals with the flotation collector while promoting collector deposition on the preferred mineral surface.
