ActiveManganese and chromium ores - Experimental methods for checking the bias of sampling and sample preparation
锰矿石和铬矿石 校核取样和制样偏差的试验方法
Application Summary AI generated
This standard specifies experimental methods for verifying whether systematic errors (bias) occur during the sampling and sample preparation of manganese and chromium ores. It is applied in the mining and mineral processing industries to ensure the accuracy and representativeness of samples used for quality control, trade settlement, and metallurgical testing. The methods are critical for reducing disputes between buyers and sellers over ore grade and composition.
