Anthropogenic antimony flow analysis and evaluation in ...

The index of ore (I 2.1) (Guo and Song, 2008) is equal to the ratio of the net import antimony concentrate (NIC) and domestic ore (DO) to the antimony yield from production (AY). Therefore, the ore index, which is represented by I 2.1, can be expressed by the following formula: (2) I 2.1 = NIC + DO / AY
