A study on the relationship between critical surface tension of wetting and oil agglomeration recovery of calcite
In this study, it was investigated that the relationship between the critical surface tension of wetting of calcite and agglomeration recovery depending on pH and amount of collector (Na oleate). For this purpose, effects of pH and the amount of collector on the agglomeration recovery were investigated and, also, zeta potential measurements and Fourier transform infrared spectrophotometer (FTIR) analyses have been carried out to determine the adsorption type of Na oleate on calcite surface. In this paper, the decisive rules could not put down as evidence of agglomeration success with the critical surface tension of wetting value as in the flotation, because there are different liquids as water and oil (bridging liquid) in the agglomeration system.
