Foreword
Instead of the standard YS/T 96-1996 "bulk flotation of copper concentrate, lead concentrate of gold, silver analysis sampling and sample preparation method." This standard
YS/T 96-1996 compared to the present standard the following modifications.
--- Will lead concentrate portion omitted;
--- Increase the quality of forecasting terms, increasing the sampling terms of landing;
--- The 3.3 "and reduction of sub-sampling method according to GB 14262-1993 or GB 14263-1993 in 4.2" and 3.5 "in strict accordance with
This standard specifies the method for sampling and sample preparation "omitted;
--- The 3.6 components samples saved from the "proper" to "dry environment at room temperature";
--- 5.4.1 adds "sample mixing method";
--- The sample preparation procedure "full amount over 0.083mm sieve" to "the whole amount of free passage 0.09mm standard sieve";
--- Modified "5.3 sample preparation procedure" in the flow chart of sample preparation.
This standard by the National Standardization Technical Committee of non-ferrous metals and centralized.
This standard is drafted by. Daye Nonferrous Metals Company.
Participated in the drafting of this standard. Tongling Nonferrous Metals Group Holdings Co., Jiangxi Copper Group, Yunnan Copper Company.
The main drafters of this standard. Cheng Xi, Liu Zhengming, Hu Xinping, Bi Jianming, Kang Peng, Li Baodi, a micro Wu, Wu Zhiqing, He Zhenghua.
This standard replaces the standards previously issued as follows.

Bulk flotation gold in copper concentrates, silver
Analysis of sampling and sample preparation method
1 Scope
This standard specifies the bulk flotation of copper concentrate associated gold, silver analysis sampling, sample preparation methods.
Sampling and Preparation This standard applies to bulk flotation associated gold in copper concentrates (1g/t ~ 15g/t), silver (≤2000g/t) analysis, scope of application
Wai. Au. 1g/t ~ 15g/t, Ag. ≤2000g/t. Gold, silver content is not within the scope of copper concentrate a reference implementation of this method.
2 Normative references
The following documents contain provisions which, through reference in this standard and become the standard terms. For dated references, subsequent
Amendments (not including errata content) or revisions do not apply to this standard, however, encourage the parties to the agreement are based on research
Whether the latest versions of these documents. For undated reference documents, the latest versions apply to this standard.

3.3 standard gold, silver content (g/t) as the quality characteristics of copper concentrate.
3.4 component samples should be stored at room temperature for 3 months in a dry environment, for verification.
3.5 Sampling and sample preparation used equipment, tools and sample container filled must be kept clean and dry. Sheng sample container should be better seal to prevent test
Kind of deterioration.
