Sep 23, 2020018332Sodium oleate is primarily used as a collector for calcite-apatite or calcite-scheelite separation. Calcite, scheelite, and apatite are sparingly soluble minerals and due to its solubility, it is difficult to measure the zeta potential below pH 7. ... C12GlyNa floated calcite with no effect on apatite flotation, whereas with C12MalNa2 ...
The hydrophobicity studies show that the selective separation of calcite and apatite can be obtained by using jojoba oil at a pH below 7.0. In this condition, the apatite is hydrophilic and calcite is hydrophobic, allowing their separation through froth flotation. Pequi, Caryocar brasiliense, is an oleaginous fruit with a strong and distinctive ...
Conventional flotation scheme is not successful for separation of dolomite from its mixture with apatite. Several processing methods utilizing both anionic and cationic collectors have been proposed to solve this problem, but they have yet to be tested on a commercial scale.

Flotation Separation Of Scheelite From Calcite Using. Flotation separation of specularite from chlorite using propyl gallate as a collector Xiangpeng Gao, a Fugang Zhao,b Mingyang Li ac and Yiming Hua Separation of specularite from iron-containing sili cate iron ore is challenging due to the similar surface properties of minerals and gangues.
The adsorption behavior of these new reagents on pure apatite and calcite mineral surfaces was studied using Hallimond tube flotation, FTIR and potential measurements. The relation between the adsorption behavior of a given surfactant on a specific mineral surface and its molecular structure over a range of concentration and pH values, as ...

Get Price carbonate depression in ...
Supernatants of apatite and even that of calcite depressed the flotation of calcite markedly in the pH range of 5 to 13. Addition of CaNO32, K2CO3, and K3PO4 also produced definite effects under various pH conditions. Apatite flotation was also affected by the mineral supernatants and by carbonate and phosphate solutions.
Apatite And Calcite Separation By Flotation. Jun 01, 2019 In this study, 2-phosphonobutane-1,2,4-tricarboxylic acid PBTCA was introduced as a depressant for the flotation separation of apatite from calcite. The micro-flotation test results showed that good floatability of both apatite and calcite were obtained at around pH 8.5 when using ...
