Feb 18, · Abstract The effects of shear strength on aggregation flotation processes for fine spodumene (particle size less than 19 μm) were investigated in this study. Sodium oleate was used as a surfactant and collector. The shear strength was controlled by varying the agitation speed of a selfmade stirring apparatus. The aggregation process was studied by measuring the continuous

The cumulative impact of habitat fragmentation results from the combined incremental effects of habitat loss, reduced patch size, increased edge, and patch isolation. The impacts are cumulative across scales and over time affect populations of organisms as well as individuals. These impacts are not related linearly to the extent of original habitat.
