The flotation separation of salt type calcium minerals is problematic, due to the similarities in their same active Ca 2+ related site for interaction with anionic collectors and similar physicochemical characteristics such as solubility, zeropoint charge, surface speciation and Casite density. The work was performed to achieve effective and selective separation .
The phosphate ore flotation is achieved through the surface electrical behavior difference among apatite, dolomite and quartz, but it is usually affected by the dissolved ions from pulp, especially Ca2+ and Mg2+. The zeta potentials of apatite, dolomite, quartz, and phosphate ore in different solutions were measured to discuss the surface electrical behaviors of them in this study.

Jan 26, 2017· Global demand and consumption of rare earth elements and compounds have led to increasing research to further our understanding of their beneficiation and recovery. Monazite is the secondmost important rare earthbearing mineral that can be exploited. In this study, the surface chemistry of monazite in terms of zeta potential, adsorption density, and flotation responses using .
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.

In this study, the separation of calcite and apatite was achieved by the depressant sodium pyrophosphate (SPP). Microflotation results showed that when .
The flotation separation of scheelite from fluorite, apatite, and calcite has been intensively investigated over the past decades and remains, in the twenty first century, one of the most challenging problems in the froth flotation field.
The hydrophobicity studies show that the selective separation of calcite and apatite can be obtained by using jojoba oil at a pH below 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 ...
Cassiterite is the most common and important tinbearing mineral, and calcite, a primary gangue mineral is generally found in tin deposit. The flotation separation of cassiterite from calcite remains a challenge due to their similar response to traditional reagents. In cassiterite flotation, sodium oleate (NaOL) and sodium silicate (SS) have been widely used as a collector and a depressant ...
To explore the impact of PAMS on the flotation separation of apatite from dolomite, the flotation experiments on mixed apatite and dolomite minerals as feed were performed at pH, and the results are presented in Table 1. It is worth noting that the mass ratio of apatite and dolomite was 1:1 and the grade of P 2 O 5 was % in initial feed.
Jun 01, 2019· In this study, 2phosphonobutane1,2,4tricarboxylic acid (PBTCA) was introduced as a depressant for the flotation separation of apatite from calcite. The microflotation test results showed that good floatability of both apatite and calcite were obtained at around pH when using sodium oleate (NaOl) as collector.
Jun 15, 2020· In the flotation separation of apatite and calcite, fatty acid collectors are adsorbed on both mineral surfaces owing to the presence of the same calcium ions on the cleavage planes,, . Therefore, the floatability of both minerals is excellent and the flotation selectivity is very low.
Aug 01, 2020· The flotation separation of apatite from dolomite can be achieved under the reagent system of adding 20 mg/L SA followed by 1*10 −4 mol/L NaOl in pH 8–11. The contact angle tests and adsorption tests indicate that depressant SA absorbed onto both apatite and dolomite surfaces and the adsorption intensity of the latter was greater than that ...
selectively depress the flotation of apatite, thus realizing the separation of apatite from dolomite. Further, the selective depression mechanism of NaPP was studied through zeta potential .
apatite and calcite Separation By Flotation. CalciteApatite Flotation Columbia University. the effect of calcite supernatant on its own flotation is also to depress it significantly in this pH range (see Figure 3) Thus, while both the supernatants of calcite and apatite depress calcite flotation under s~ilar pH conditions, their effect is.
