Abstract NALCO 8457 is a high molecular weight, anionic polyacrylamide-based flocculant designed primarily for solid-liquid separation processes in the mining and mineral processing industries. It is specifically formulated to enhance settling rates in tailings thickeners and clarify overflow water in applications such as bauxite refining (Bayer process) and base metal flotation circuits.
1. Chemical & Physical Properties
| Property | Specification | | :--- | :--- | | Appearance | White, free-flowing emulsion | | Chemical Family | Anionic Polyacrylamide (Emulsion) | | Specific Gravity (at 25°C) | 1.02 – 1.06 | | Viscosity (as supplied) | 500 – 1500 cP | | pH (as supplied) | 6.0 – 8.0 | | Charge Density | Low to Medium Anionic | | Molecular Weight | Very High (>15 million Daltons) |
2. Mechanism of Action
NALCO 8457 operates via bridging flocculation. The long polymer chains adsorb onto multiple negatively charged solid particles (e.g., red mud, iron ore fines, or tailings), neutralizing surface charges and forming large, dense agglomerates (flocs). These flocs settle rapidly due to gravity, leaving a clarified supernatant.
Key advantage: Unlike low molecular weight coagulants, its high molecular weight allows effective bridging without overdosing, which can cause re-stabilization of colloidal particles.
