  • Patent number: 5908801
    Abstract: A process for the production of synthetic dolomite comprising: grinding a dry and low impurity level mineral dolomite; incorporating additives selected from the group consisting of iron as Fe.sub.2 O.sub.3, silica (SiO.sub.2) and magnesium hydroxide Mg(OH).sub.2, calcium hydroxide Ca(OH).sub.2 or a combination of both, in order to react and integrate dolomite impurities as the desired silica (SiO.sub.2), iron (Fe.sub.2 O.sub.3), and alumina (Al.sub.2 O.sub.3), in the dolomite; wholly mixing these additives with the ground dolomite in a mixer machine; compacting the mixed materials in order to form briquettes; sieving the briquettes of compacted material to eliminate fines; burning the briquettes to a temperature of 1,700 to 2,200.degree. C. to guarantee a complete sintering; cooling the briquettes and sieving the cooled briquettes.

  • Patent number: 5811069
    Abstract: A long term stabilized magnesium hydroxide suspension which can be stored for at least six months without substantial agitation and without undergo substantial settlement nor solid hard substrate formation, comprising a solid content of about 51% to 62%; a water content of about 38% to 49%; a viscosity of about 50 to 400 cp.; an average particle size of about 1 to 2.5 microns; a Mg(OH).sub.2 content of about 50% to 60%; an equivalent magnesium oxide content of 34% to 42%; and including an anionic polyelectrolyte as a dispersant agent, and which is obtained by washing, filtering and repulping magnesium hydroxide solids to obtain agglomerated solid particles, dispersing the agglomerated solid particles by comminution in a dispersing equipment, to reduce the particle size providing a dispersed product, grinding the dispersed product to additionally reduce the particle size to about 2 microns; and adding an anionic polyelectrolyte at a concentration of at least 25%, in an amount of about 0.5 to 1.
