A process for separating ore particles from gangue particles comprises the steps of (1) conditioning the particles with an agent comprising a compound having both a surface-selective functional group and a detectable moiety, to selectively coat either the ore particles or the gangue particles, to the substantial exclusion of the other; (2) detecting the coated particles; and (3) separating the detected, coated particles from the substantially uncoated particles. In one embodiment, the detectable moiety is fluorescent and detecting is performed under ultraviolet radiation.

Sorting of ores with detectable compounds

The instant disclosure relates to a method of tracing the flow of a solution for extracting values from an ore, wherein such extraction leaves behind an extracted ore, which method comprises

Identification of fluid flow under in-situ mining conditions

Organophosphorus acid compounds react by a metathesis reaction in a liquid media with tetravalent metal ions to yield layered crystalline to amorphous inorganic polymers having the empirical formula M(O.sub.3 PR).sub.2 where M is the tetravalent metal and R is an organic group covalently bonded to phosphorus.
