Foreword
YS/T 53 "Copper, lead, zinc ore tailings and chemical analysis method" is divided into three parts.
--- Part 1. Determination of the amount of gold fire assay enrichment - flame atomic absorption spectrometry;
--- Part 2. determination of gold by Flow Injection Micro - column separation -8531 fiber enrichment - flame atomic absorption spectrometry;
--- Part 3. Determination of the amount of silver by flame atomic absorption spectrometry.
This is Part 1.
This section is in accordance with GB/T 1.1-2009 given rules drafted.
The partial replacement of YS/T 53.1-1992, this portion of YS/T 53.1-1992 compared to the main changes are as follows.
--- Deleted TMK spectrophotometry;
--- Measured by the scope of 0.001g/t ~ 1.0g/t adjusted to 0.05g/t ~ 3.0g/t;
--- Omitted "reference standard" one;
--- Text format has been modified;
--- Complements the precision, quality assurance and control provisions.
The non-ferrous metal part by the National Standardization Technical Committee (SAC/TC243) centralized.

Copper, lead, zinc ore tailings and chemical analysis methods
Part 1. Determination of gold content
Fire Assaying Enrichment - Flame Atomic Absorption Spectrometry
1 Scope
YS/T of the provisions of section 53 of the copper, lead and zinc ore tailings and determination of gold content.
This section applies to copper, lead, zinc ore tailings and determination of gold content. Measuring range. 0.05g/t ~ 3.00g/t.
2 Method summary
Sample obtained by melting lead button ingredients containing precious metals, gold and silver together and then get blown ash particle. Together with the amount of grain mixed acid dissolved, the original flame
Absorption spectrometric method for the determination of gold content.
3 Reagents
