| Abstract: | Dealing with the problem of representativeness of sampling for imported concentrates minerals with container shipment,the moisture distribution of different parts before and after unloading the cargo and the representativeness of shovel sampling with different sampling numbers and three common sampling tools were studied.We obtain results about the moisture distribution of different parts before and after unloading and the moisture difference caused by sampling numbers sampled with shovel.Also the differences of representativeness of sampling between different sampling tools are found. |
