摘要
对黑钨矿与磁铁矿的复合聚团进行了扫描电镜研究，建立了复合聚团模型，推导了黑钨矿与磁铁矿粒间的磁作用能计算公式．计算结果表明，在颗粒间距为２５～１００ｎｍ以至更远的距离内，黑钨矿与磁铁矿颗粒之间存在着吸引势能，可相互吸引形成复合聚团；并从理论上较好地解释了黑钨矿与磁铁矿形成复合聚团的内在依据及复合聚团具有较大致密度和较高稳定性的原因．
Scanning electron microscope(SEM) study on the co-aggregation of wolframite and magnetite is done, a model is set up to describe the process of co-aggregation and a calculation formula for magnetic interaction between wolframite and magnetite is deduced in the paper. The calculation results show that When the distance between two particles is from 20nm to 100nm or more, only exists attraction potential energy between wolframite and magnetite particles and co-aggregation can be formed by the mutual attraction force. This conclusion can theoretically explain why co-aggregation can be formed between wolframite and magnetite and the aggregation has higher density and stability
