Process for the production of sintered bauxite spheres
Patent
·
OSTI ID:6515532
A process is disclosed for producing high strength sintered bauxite spheres usable as fracture propping agents in oil or gas wells. Proppants are produced by continuous spray-granulation of an aqueous binder-containing aluminous ore suspension to form granules which are subsequently sintered. Suitable starting materials include ores of high aluminum silicate content.
