Separation of Sodium Sulfate by the Flotation Method

The flotation characteristics of pure sodium sulfate crystal in the saturated solution with both sodium sulfate and sodium chloride were examined. On the basis of results obtained, separations of sodium sulfate from the recovered salts, which prepared from the imitative electrolyte, were carried out by using a FW-50 type flotation test machine. The results summerized as follows:US3917801A - Flotation of boric acid from sodium sulfate,,US3917801A - Flotation of boric acid from sodium sulfate obtained during the processing of borate ores - Google Patents.

The results showed that when sodium oleate was used alone, the three minerals floated well and were difficult to separate.

Flotation studies of fluorite and barite with sodium,

01/01/2019· SPS was used as a collector to study the flotation behavior of fluorite and barite with SHMP as a depressant. The flotation results showed that SPS performed well in an alkaline pulp even at a low temperature (5 °C), while the flotability of fluorite and barite were almost the same. At pH 11, the presence of SHMP obviously depressed fluorite rather than barite and SHMP exhibited good selective inhibition to fluorite. FlotationFlotation of sphalerite and pyrite in the presence of,,01/06/2001· The effect of sodium sulfite on pyrite flotation is more pronounced than on sphalerite flotation with flotation recoveries being reduced by half at a sodium sulfite concentration of 2×10 −4 mol dm −3.

Flotation of boric acid from sodium sulfate obtained,

For example, the Ph of the flotation slurry at 38°C. should be between 4 and 5, preferably about 4.5. To produce a slurry with a pH of 4.5 at 38°C., the pH at the temperature at which the reaction between the boron mineral and the sulfuric acid should preferably take place (80°C.) should be about 3.3.Lead recovery by flotation with sodium lauryl sulfate,Lead recoverable slag is of economic and environmental importance.
