It is a NaNO3 flotation solution with SpG 1.20 (not saturated) and will float most common eggs and oocysts, but will distort Giardia cysts. In the laboratory today, we will use ZnSO4 instead of NaNO3. Technique Mix about 5 gm of feces with 20 ml of flotation solution in a plastic cup or other suitable containers.

12.10.2015Figure 1 shows that pyrite exhibits good flotation performance at pH range of 4 to 9 when in the absence of CuSO 4, and as much as 80% of the pyrite can be floated.But at a pH range of 9 to 12, pyrite is depressed and the recovery decreases significantly with the increase in pH. The decrease in recovery is attributed to the formation of iron hydroxide on the pyrite

Flotation tests on pure samples illustrated that PGA has beneficial effects on magnetite depression (with negligible effect on quartz floatability) through reverse flotation separation. Flotation of the artificial mixture ground sample in the presence of PGA confirmed the benefits, giving a maximum Fe recovery and grade of 84.4 and 62.5%,
