Rare Metals Corporation (RMC) E-Mail: raremetalsrmcgoldsample preparation for assaying copper ore sample,Assay - InvestopediaThe process of analyzing a physical sample to determine its composition. In financial markets, the term assay usually refers to the chemical analysis of a mineral or ore sample to ascertain its content of precious metals or minerals, such as gold, copper, or uranium.John Frank
The goals of this application study are to: • Compare assay results from prepared samples with those from unprepared samples. • Compare assay results of portable XRF from prepared/unprepared samples with lab assay data. • Identify copper-molybdenum (Cu-Mo) anomalous zones at depth using portable XRF assay data.
Standards were prepared in either 2% HNO3 (copper, silver) or. 15% aqua regia (gold, palladium, platinum) to simulate the dissolution of a button sample after fire-assay sample preparation. Results and Discussion. The ability to accurately measure low concentrations was assessed by establishing low-level calibration.
Copper ore samples were prepared for analysis via a proprietary sample preparation procedure, which resulted in solutions containing 10-15% acids with dissolved solid contents up to 4000 mg/L. The digested samples were analyzed with a PerkinElmer. AAnalyst™ 400 atomic absorption spectrometer, operating in.

Jan 17, 2017 . Conventional preparation and assaying procedures were used. Copper is analyzed by multi acid digestion and atomic absorption spectroscopy. Gold is assayed using a fire assay procedure. Specific gravity is systematically measured on core samples. The Candelaria Copper Mining Complex implements.
Ore grade analysis provides a higher dissolution for samples with a higher metal concentration. This is a more precise method than the trace geochemistry.
