Abstract (en)
[origin: FR2930265A1] The process comprises mixing the dust in a tank in the presence of a first binder comprising a polymer (5-20 wt.%) of molecular weight higher than 500000 g/mol, separately adding a second binder comprising silicate (5-40 wt.%) in the tank, and compacting the obtained agglomerates. The first binder is present in the form of an inverse emulsion. The organic polymer is water soluble, has an ionicity of 10-90 mol.%, and comprises an ionic, cationic, zwitterionic and/or anionic monomer, a nonionic monomer and optionally 0.02-2 mol.% of hydrophobic monomer.

The organic polymer is water soluble, has an ionicity of 10-90 mol.%, and comprises an ionic, cationic, zwitterionic and/or anionic monomer, a nonionic monomer and optionally 0.02-2 mol.% of hydrophobic monomer. The weight ratio of dry polymer to oil of the inverse emulsion is 0.5. The ratio of polymer in inverse emulsion to dust is 0.2-0.5 wt.%.
