CELESTITE-GYPSUM SEPARATION BY FLOTATION G. BULUT, S. ATAK and E. TUNCER ... Denver flotation cell using tap water. A pH adjustment was made with dilute NaOH or H 2 SO 4 solutions.
Too coarse ore particles (greater than 0.1mm) and very fine ore particles (less than 0.006mm) do not float well, and the recovery rate is low.. In the flotation of coarse particles, due to the larger weight, the shedding force of the ore particles increases.So, you need: (1) Use a sufficient amount of the most effective collector.
In this study, the selective adsorption mechanism of gypsum on the surface of dolomite is investigated using gypsum as a gangue mineral depressant in phosphate flotation.

Gypsum in ores with a high clay mineral content can change the flotation outcome. Gypsum inhibits the formation of bentonite network structures. Flotation in the presence of clay minerals depends on clay particle associations.
Flotation studies were also carried out in the Denver cell to obtain marketable celestite concentrates from an ore sample from same mine. Parameters such as pH, collector type and dosage were examined using microflotation tests. ... T1 - Celestite-gypsum separation by flotation. AU - Bulut, G. AU - Atak, S. AU - Tuncer, E. PY - 2008/4.
The flotation product easily leached to 46% Pb (with essentially no further lead loss), while the maximum with the original feed was ca. 39% Pb; apparently some refractory phases are rejected by flotation. Flotation alone did meet the <2% Fe criterion for the gypsum product using sulphonate at pH 3.2 giving a gypsum recovery of ca. 75%.
