Abstract
Abstract
| The presence of calcium ion in iron ore pulps causes heterocoagulation of rnontmorillonite on hematite leading to indiscriminate dispersion. Two methods were investigated to control the adverse effect of montmorillonite: a chemical method using such complexing agents as EDTA and sodium tripoly- phosphate, and a mechanical method involving ultra- sonic treatment. Their roles in controlling the adverse effect were investigated by zeta potential measurements, starch adsorption tests, and flocculation and selective flocculation tests. |
