Se.aration of targe. e.e.e.ts or mine.als from the.r host rock or ore.is e.se.tial to succe.sful mining ope.ation. The.ine.itable.loss of a portion of the.de.ire. mate.ial that accompanie. e.ch ste. in the.e.traction proce.s must be.docume.te. to de.e.op the.ope.ational protocol. Supe.position of the.characte.istic X-ray fluore.ce.ce.spe.tra of he.d (crushe. rock ore.particle., pre.proce.sing) and tail (post-proce.sing particle.) sample. provide. a dire.t visual comparison of re.ative.pe.k size., and the.e.y the.re.ative.conce.trations, of e.e.e.ts of inte.e.t. If the.he.d and tail pe.ks are.ide.tical, none.of the.e.e.e.t was re.ove.e. in the.e.traction proce.s. At the.othe. e.tre.e.if the.tail pe.k “flat line.”, i.e., the.e.is no pe.k, the.e.was 100% re.ove.y of that e.e.e.t. Standardle.s visual comparison is valid if the.same.mass of ide.tical starting mate.ial is incorporate. into the.he.d and tail sample.analysis pucks, and XRF analytical conditions are.ide.tical. The.conside.able.time.and e.pe.se.of acquiring and calibrating the.standards associate. with XRF analysis of 75 or more.e.e.e.ts are.avoide., a significant advantage.during initial broad scre.ning of an e.pe.ime.tal e.traction proce.ure. Full quantitation by XRF or an alte.nate.te.hnique.can proce.d at a late. proje.t stage. if de.ire.. The.approach re.ains and pre.e.ts all fe.ture. of the.original data, thus e.iminating que.tions about data quality, standards and the.r calibration, and data manipulation in proce.sing from raw counts to conce.trations in printout table.. This form of display is ide.l for both the.mining profe.sional and such le.s te.hnical groups as corporate.staff, inve.tors, re.ulators, and the.public. e.ample. pre.e.te. he.e.n are.for he.p le.ching;the.protocol can be.applie. as we.l to any of the.othe. traditional ore.proce.sing and be.e.iciation proce.ure., e.g., gravity conce.tration, magne.ic and e.e.trical se.aration, froth flotation, and ore.sorting.
