The present invention relates to a binder composition comprising a) component A comprising polymer(s) A1 having primary and/or secondary amino groups, wherein polymer(s) A1 has(have) a primary and secondary amine group nitrogen content of at least 1 wt.-% and b) component B comprising component B1 which is 1,3-dihydroxyacetone, glycolaldehyde, glyceraldehyde or any mixture thereof, wherein the polymer(s) A1 has(have) a total weight average molecular weight Mof at least 800 g/mol.

Binder composition comprising polyamine(s) as well as 1,3-dihydroxyacetone, glycolaldehyde and/or glyceraldehyde for composite articles

The present invention relates to a binder composition comprising component A comprising polymer(s) A1 and optionally component B comprising component B1 which is selected from the group consisting of a mono-saccharide s, disaccharides, hydroxyacetone, glycolaldehyde and mixtures thereof, wherein polymer(s) A1 comprises at least 70 wt.-% poly(amino acid)s based on the total weight of the polymers) A1 and has (have) a total weight average molecular weight Mof 800 g/mol to 10.000 g/mol, wherein the binder composition comprises 60 to 100 wt.-% polymer(s) A1, and 0 to 40 wt.-% component B1, based on the total weight of the sum of polymer(s) A1 and component B1, wherein the weight amounts of the polymer(s) A1 and component B1 are selected such that the total weight of the sum of polymer(s) A1 and component B1 is 100 wt.-%.

Binder composition comprising poly(amino acid)s for fiber composite articles

In a device and a method for extracting non-magnetic ores from a pulp comprising non-magnetic ore particles and having a solid fraction of at least 30 mass percent, the pulp flows continuously through a reactor in the direction of flow and magnetic or magnetizable magnet particles that form ore magnetic particle agglomerations with the non-magnetic ore particles are added to said pulp. The ore magnetic particle agglomerations are moved by a magnetic field into an accumulation range of the reactor, and are then discharged out of reactor range and separated into ore and magnetic particles. In a device and a method, the separated magnetic particles are treated, in particular hydrophobized, such that during a new interaction with non-magnetic ore particles, new ore magnetic particle agglomerations are formed. Accordingly, a high yield of ores can be obtained and the mine can be operated in an economical and environmentally friendly manner.
