特征元素增量法直接测定富镍矿石的品位

The measure on rich Ni ore by the characteristic chemical element increases the quantity method

采用便携式高分辨率能量色散X射线荧光仪和特征元素增量法对未知富镍矿石进行测定。实验结果表明：对含Ni为1％～3％的镍矿石，增量法分析的相对误差小于2％，达到部分允许误差限要求。

The application of high sensitive portable Energy dispersion x-ray fluorescence spectrometer （EDXRF） and the The characteristic chemical element increases the quantity method is used to measure the rich Ni ore,Tests on Ni ore which content 1%-3% show that the relativity error is less than 2%, Attain the part allows an error margin request.
