The tailing samples were mixed using a mechanical agitator for 20 min to ensure homogeneity. Representative samples were collected for the flotation and mineralogical analyses of raw ore. ... which is in contrast to that observed for the apatite–water system. During apatite flotation, the negatively charged sulfate ions …
In this study, the influence of anhydrite on the flotation behavior of apatite in a fatty acid system was systematically investigated using micro-flotation tests, solution …
The supernatant liquid was considered for all zeta potential measurements. In all experiments, the solution pH was adjusted using either 1 M HCl or 1 M NaOH as needed. 2.2.3. Flotation Experiments Preparation of the Flotation Feed. Tailing samples were mixed using a mechanical agitator for 24 h to ensure sample homogeneity.
The results of the confirmatory experiments of apatite flotation, which were performed using different types of water (freshwater, tailing dam water (without treatment) and water treated with DAF in different conditions) showed that the highest values of P 2 O 5 recovery and grade were obtained when the DAF process was performed with a pre ...
This article indicates that the introduction of submicron bubbles (known as nanobubbles, "NBs") to conventional flotation could improve the separation efficiency of valuable minerals from their associated gangue phases. Processing of materials that originated from tailings of industrial plants (with a wide range of particle size distribution, …
