Detailed explanation of Shajin 999 standard detection method

During the process of gold refining and processing, Shajin is a common raw material.For sand gold with a gold content of up to 999, precision detection methods need to be used to ensure its purity and quality.This article will introduce the standard detection method of Shajin 999.

1. Sample and pre -processing

First of all, before the Salin 999 standard detection, sampling and previous processing steps are required.Under normal circumstances, a certain amount of samples are obtained from the raw materials, and the processing steps such as grinding, mixing, etc. to ensure the representativeness and uniformity of the sample.

2. Fire test method

The fire test method is one of the commonly used gold content testing methods.When conducting a fire test, first place the samples that are processed in the pupa, add an appropriate amount of melting agent (such as boric acid), and then melt the material and separate the yellow liquid phase through high temperature heating.

Then, after cooling, observe the color and morphological changes of the product, and determine whether it contains golden ingredients according to the characteristics of different elements in the fire test.

3. Chemical analysis method

Chemical analysis is another method that is commonly used in Shajin 999 standard detection.This method determines the composition and proportion of the element contained in it by dissolving the test substance and using a specific pharmaceutical reaction.

Specific operations include dissolving the substances to be tested in appropriate solvents, and add oxidant or repayment to a reaction to generate quantitative or seizure or concentration. Then use spectral instruments or other instruments to qualitatively or quantitative analysis of the substances.

4. X -ray fluorescent spectrum method

X -ray fluorescent spectral method is a non -contact, fast and accurate element analysis technology, which is widely used in the Sajin 999 standard detection.This technology uses X -ray to stimulate the material to generate feature X -ray fluorescent signals, and determines the composition and content of the material through the recorded instrument records and recognition of these signals.

In conclusion,

The detection of Gold Content in Sand Gold is Crucial for ENSURING ITS PURITY and Quality, ESPECIALLY When It Reaches the Standard of 999 Purity Level. Thods such as fire assay, chemical **** ysis, and x-ray Fluorescence Spectroscopy Are CommlyEmployed for this purpose.
