| Abstract: |
| 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 |
