Abstract
A mixture of dry ingredients capable of forming a crosslinked polymer upon hydration for use as a fracturing fluid in processes for recovering minerals from subterranean formations. The dry mix comprises a polysaccharide, a crosslinking agent selected to become active after the polysaccharide has been substantially hydrated, and a pH-adjusting agent to facilitate the crosslinking reaction. The mix is hydrated while being pumped and reaches maximum viscosity in the subterranean formation.
