Fluorite samples from the tungsten separation tailings of the Shizhuyuan Mine, Chenzhou, Hunan Province, P.R. China, were tested using a small-scale continuous flotation test unit, and ...
As shown in Table 3, after bulk flotation of fluorite and barite with valonea extract to depress calcite, 93.83% of the calcite remained in the tailing. Obviously, the depressing effect to calcite by valonea extract in the bulk flotation was striking. ..., but they could be reduced by several stages of scavenging the flotation tailings. At the ...
Fluorite is an important strategic mineral. In general, fluorite ores will contain a certain amount of calcite gangue mineral. Thus, they need to be separated from each other. For an economic separation, a reverse flotation process is used to float calcite gangue from fluorite. However, little information on the separation is available.
In addition, the flotation results of the tailings from Jiangxi containing fluorite and calcite, indicated that the grade and recovery of fluorite increased from 87.18% and 40.99% for 0...
A Study on Molecular Mechanics Analysis Flotation Collector in the Process Management Fluorite Tailing Mining Abstract: Recently, the natural mineral resources became short. In the process of fluorite floatation and tailing recycling, the key point is to find out collectors which have good selectivity to fluorite and effective inhibitor of gangue.
After flotation, the concentrate and tailing were collected, filtered, dried, weighed and the recovery was determined based on solid weight distributions between the two products. For artificial mixed minerals, mass ratio of fluorite and quartz was 1:1 for binary mixture (1 g fluorite + 1 g quartz).
The recovery scheme consisted of (1) grinding the ore to minus 48 mesh, (2) fluorite rougher and cleaner flotation, (3) desliming the rougher fluorite flotation tailings at 20 Jjm, (4) mica flotation, and (5) silicate rougher flotation. Acid-grade fluorspar, mica, free silica (Si02) sand, and low-grade beryl
The flotation circuit consists analysis of the sample. First, 200 g of dry sample together of rougher flotation and two-step cleaner flotation, achiev- with 2 l of water was mixed in a conditioning tank for ing the fluorite recovery of about 70%.
The flotation lasted for 5 min before the products (concentrate and tailing) were collected, dried, and weighed. The dry weights of the two products were measured and used to calculate the recovery. and the reported results were averaged over at least three repeated tests. The flowsheet for the micro-flotation experiments is presented in Figure 4 .
Recently, the natural mineral resources became short. In the process of fluorite floatation and tailing recycling, the key point is to find out collectors which have good selectivity to fluorite and effective inhibitor of gangue. Most reagents primarily come from agricultural byproduct and some chemical byproduct. However, the tailing mineral is complex and difficult to collect, which brought ...
The experiments results indicated a fluorite concentration with CaF 2 of 95.78%, as well as recovery of 64.34% for CaF 2, was obtained from the tailings (average CaF 2 grade of 25.65%) by an innovative flotation technique.
It is found that the mill tailings contain 14.92% of CaF2, 13.16% of CaCO3 and 0.49% of Zn. The use of new compositions of modifiers in flotation of fluorite allows production of standard grade concentrates with CaF2 content of 93.19–95.54% at the recovery of 52.75–30.15%. Zinc recovery is 38.84% with the yield of 42.11% Zn concentrate.
Flotation tailings of a polymetallic mine in Inner Mongolia contain fluorite resources. Due to the influence of the tungsten-tin flotation reagent and the ore embedded characteristics in the early stage, the fluorite flotation concentrate grade is up to 92%, and the recovery is about 30%. The fluorite resources in the tailings were not effectively recovered.
The flotation tests of the tailings were conducted on a laboratory flotation machine of XFD (Jinlin Exploration Machinery Plant, Changchun, China) at a speed of 1992 rpm. The flotation pulp of the tailings was obtained by adding 500 g samples and 1.0 L water, followed by stirring for 2 min.
The processing of fluorite mainly uses hand-selection, gravity separation and flotation, in which flotation is the most common. Come to Mining Pedia for the details flowsheet! 12:06:23

Fluorite is one of the common non-metallic minerals, the chemical formula is CaF 2.It is widely used in metallurgy, chemical engineering, ceramics, glass, casting and other industries. Common fluorite beneficiation methods mainly include manual selection, gravity separation and flotation, among which flotation is the most used. There are 8 main factors affecting the fluorite flotation effect.
In this study, the effect of artificial fluorite suspension as flocculant has been investigated using fluorite flotation tailing, organic matter after processing acrylic resin and microorganism after C. O. D treatment.
For single mineral flotation tests, the floated and tailing fractions were collected separately and dried afterwards before being weighed. For artificially mixed minerals flotation, the concentrates and tailings were assayed (Chinese standards GB/T 5195.1-2006) to acquire the grades of fluorite and barite, before calculating the recovery amounts.
In addition, the flotation results of the tailings from Jiangxi containing fluorite and calcite, indicated that the grade and recovery of fluorite increased from 87.18% and 40.99% for 0 days to 93.00% and 46.01% for 8 days, respectively, indicating that the separation of fluorite from calcite could be achieved via increasing the long-term ...

Fluorite and scheelite (CaWO 4) are both calcium-containing minerals that are commonly associated with each other in natural deposits (Wei et al., 2017a, Wei et al., 2017b). During the flotation of scheelite-fluorite ores, scheelite is usually floated as a froth product, while fluorite is recovered from the scheelite flotation tailings.
