To process ore or mineral to increase its concentration of valuable minerals, especially in mining; to receive a benefit.
From Latin 'beneficiatus,' past participle of 'beneficiare' (to do a favor or benefit). In mining, the term was specialized to mean 'to make ore more valuable by processing.'
Mining engineers use 'beneficiate' constantly when describing how they turn low-grade ore into concentrated material—it's a word that makes manual processing sound like chemistry and science.
