How to sample calcite ore
Calcite (and Aragonite) Common Minerals University
Since calcite can have so many appearances, the simplest way to determine whether a sample contains calcite is to test its reaction to a dilute acid like household vinegar Calcite will readily react with acid to ‘effervesce’, 2021年6月1日 Mineral distributions can be determined in drill core samples from a Carlintype gold deposit, using microXray fluorescence (µ XRF) raster data MicroXRF data were Quantitative Mineral Mapping of Drill Core Surfaces I: A Method In porphyry deposits, ore minerals are in small veins within a hydrothermally altered host rock, generally a porphyritic felsic to intermediate composition intrusive rock Porphyry ores are not particularly highgrade, but the deposits 932: Hydrothermal Ore Deposits Geosciences Calcite, like most carbonates, dissolves in acids by the following reaction CaCO 3 + 2 H + → Ca 2+ + H 2 O + CO 2 The carbon dioxide released by this reaction produces a characteristic effervescence when a calcite sample is treated with Calcite Wikipedia
