The objective of this work was to effectively separate muscovite from gangue minerals present in a mica ore through the use of froth flotation with an amine collector and calcium lignin sulfonate depressant. The surface chemistry of the ore minerals in the presence of various flotation reagents was investigated followed by flotation tests …
MICA FLOTATION. The thickened deslimed pulp at 50% solids is conditioned with sulphuric acid for about 3 minutes at a pH of 1.5 to 2.0. This usually requires from 1 to 5 lbs. of sulphuric acid per ton of ore. After the short acid conditioning step the balance of the mica flotation reagents are added to the second conditioner tank.
depending on the ore properties. Usually, froth flotation takes place in phosphate enrichment processes, since it is cheap, convenient, and well developed. Nevertheless, it is a complex technique ... phlogopite, mica, titanium-augite, pyrite 14 600 Jordan Marine sedimentary N.A. N.A. 8 1000 Saudi Arabia Marine sedimentary N.A. N.A. 6.2 1400 ...
Take for example an albite ore from the Mugla–Milas region in Turkey, which contains high level of titanium and iron oxide minerals and small amount of mica minerals. Single-stage flotation with fatty acid based collector in an alkali medium can be effectively used to remove main colored impurities together from the albite ore.
In the first flotation stage, mica is removed with an amine collector. In the second stage, titanium and iron oxide minerals, such as ilmenite and magnetite, are removed using an anionic collector. In the third stage, feldspar is activated with fluoride ions and floated with an amine. ... Depending on the nature of the ore being treated and the ...
The influence of clay minerals on flotation performance has been extensively studied by making synthetic samples with different percentages of clays but the impact of a mixture of clays in an ore ...
Natural starch can be used to depress talc, mica, and sulfide minerals [10, 11]. It can also be used as the specific depressant for the reverse flotation of hematite. ...

mica. Mica exists in pegmatite ore bodies that, in most cases, contain either lithium or rare earth oxides. Biotite as a major mica mineral is rich in iron and magnesium and presents …
Mica ore flotation Flotation experiments on the mica ore were carried out in a 3 L Denver flotation cell at an air flow rate of 4.5 L/min using Cp-102a as frother. For each test a fresh batch of ore (500 g) was rod milled wet and then transferred directly to the flotation cell where the pulp level was adjusted to a set height by adding tap water.
When Ca(II) and Mg(II) were used as activators in the artificial-mixed-ore flotation experiments, concentrates with recoveries of 75.6% and 76.3% and Li2O …
Talc-magnesite ore from Hnúšt'a-Mútnik deposit in Slovakia was studied for the possibility of talc benefication using collectorless flotation. Ore samples were subjected to contact angle ...
Weathered pegmatite ores from Alabama, Georgia, and North Carolina and two schist ores, a California micaceous schist and an Alabama graphitic-mica schist, were studied in these investigations. Petrographic analyses of the various ores are given in table 1. The weathered mica pegmatite ores used in the investigations w…
Xu et al. reported that during the flotation of eclogite rutile ore, some of the gangue minerals like mica and apatite were easy to grind, and this generated vast amount of slimes from grinding process, which in turn lowered the flotation recovery of rutile due to the presence of those slimes (Xu et al., 2016).
Effect of play gangue minerals in sulfide flotation: Part 2: Mechanisms, Submitted to Minerals Engineering). The entrainment effects of mica were also evidenced to be concentration dependent. For coarser fractions of mica added to the ore pulp, where the degree of entrainment now increases with mica size, an increase in concentration of …

The copper ore flotation rate constants were 0.51 s −1 and 0.49 s −1 in the presence of 15 wt.% of kaolinite and 15 wt.% of illite, respectively, and 0.33 s −1 in the …
Once the mica ore has been ground into a fine powder, purification methods are employed to remove impurities and enhance the purity of the mica powder. ... Flotation uses chemical reagents to selectively separate mica from other minerals, while magnetic separation utilizes magnetic fields to attract and isolate magnetic minerals, leaving …
The efficacy of spodumene conditioning can also be impacted by poor performance of upstream operations such as desliming and mica flotation, or the presence of residual dissolved metal ions (Ca 2+ or Mg 2+) in the pulp that can activate silicate gangue minerals (Munson and Erickson, 1946, Cao et al., 2021, Quezada and Toledo, …
Merensky Reef ore was sourced from the Impala Platinum mine as run of mine ore and has been used in an extensive programme investigating the floatability of this ore (e.g. Wiese et al., 2005).The bulk samples were crushed, blended, riffled and split using a rotary splitter into 1 kg samples at the Centre for Minerals Research at the University …
The flotation method is mainly used in the recovery of crushed mica and fine-grained mica in the sand and gravel industry, especially the mica resources in the tailings. In actual production and application, the preliminary process flow should be determined according to the nature and characteristics of the actual ore.
Flotation tests were carried out on ore samples bearing muscovite, biotite and quartz. Using sodium carbonate and calcium lignin sulfonate, Browning and Adair …
