How to minimize the error of the sample during the sample preparation process?

In order to minimize the error of the sample during the sample preparation process, the following four points should be achieved:

(1) Finalizing the sample by using a narrower;

(2) In the case of shrinking the sample, the relationship between the particle size level and the minimum particle size of the sample should be met, so that the retention sample can still maintain the representativeness of the original ore sample;

(3) In the shrinkage, it is necessary to prevent the loss of the sample and the contamination of foreign matter;

(4) The sample preparation room must be dedicated, the room is not affected by the environment (such as wind, rain, ash, light, heat, etc.), and it must be dust-proof, and the ground should be smooth and covered with steel plates.
