Abstract
A basic substance is opt. added to raise the pH, or the pH may rise spontaneously. A source of metal ions is opt added to the particulate material, e.g. a suspension of a water-sololuble metallic constituent or a soln. of a water-soluble metal salt. The treated material is opt. briquetted, pelletized or extruded. Pref. uses are consolidation of earth by injecting formic acid; binding foundry sands; As cement%; binder for pelletizing or briquetting; consolidation of mineral heaps preventing atmospheric pollution and Aeolian erosion losses; recycling metal oxide dusts in a usable form to metallurgical processes and thermal storage blocks.
