quantitative analysis of silver in ore search results

Quantification of gold and silver in minerals by laser ...

Oct 01, 2017  The possibility of qualitative, semi-quantitative and quantitative determination of precious metals gold and silver in ore and surrogate samples using conventional LIBS was demonstrated. For surrogate samples, the LODs for gold (Au I 267.59 nm) and silver (Ag I 328.06 nm) are of the order of 1 μg/g.

Cupellation Process - Gold Refining Machine

Cupellation (fire assay) is a quantitative analysis technique that is used for determining the amount of precious metals such as gold and silver in ore, concentrate or any other alloy. This process is based on the principle that precious metals do not oxidize or react chemically in high temperatures. By the way since the past, there has been ...

Assaying Ores, Concentrates, and Bullion

The value of a quantitative analysis depends on how representative the sample is of the total bulk of material to be tested. No ore or mineral deposit is uniform throughout; consequently, an analysis of a sample consist- ing of a single specimen or a few randomly chosen pieces of rock is useless

Quantification of gold and silver in minerals by laser ...

The performance of laser-induced breakdown spectroscopy (LIBS) to identify and quantify gold and silver in ore samples was evaluated. Ores from a gold-producing mine and samples artificially doped with Au and Ag solutions to previously defined concentrations (surrogates) were prepared as 50-mm pellets prior to LIBS analysis. Silver detection and intensity measurement was straightforward for ...
