铜矿石柱浸过程中颗粒群的收缩变形研究
Shrinkage Deformation of Particle Swarm in Leaching of Copper Ore
摘要
Abstract
Based on the geometric difference of intergranular structure before and after leaching by sulfuric acid ,the mesoscopic structure changes of particle swarm was studied .The development regular of mesoscopic structure parameters and mesoscopic mechanism of shrinkage deformation were discussed .The results show that during leaching ,shrinkage deformation of particle swarm is the result as combined change within particle morphology ,porosity and connection form and so on .The changes are realized by more than once self-organize process .When one of the characteristic parameters changes ,mesoscopic structure of partial swarm will also change ,which will lead to the change of metal leaching rate .关键词
