4.3　Sampling Design for Ore Beneficiation Test

4.3.1　Sampling design shall be prepared in terms of detailed geological survey or geological exploration report，mine construction plan and requirements from laboratory.

4.3.2　The samples that can represent the whole deposit shall be adopted for metallurgical testwork.During mining preparation phase，the representative samples from early stage production of 5 to 10 years shall be adopted.

4.3.3　When there are two or more sorts or grades of ore in the deposit that can be collected separately，the samples shall be collected separately.

4.3.4　The representativeness of sample shall be basically consistent with the feed ore.The samples shall include major and associated useful component content，mineral composition，ore structure，mineral dissemination size feature and oxidation degree etc.

4.3.5　Sampling design shall include sorts and quantity of samples，location of sampling points，sampling method，sampling construction，sample preparation，matching and packaging.
