Recovery of feldspar from trachyte by flotation

Aug 01, 2006 In this study, recovery of feldspar from trachyte by flotation was studied. A feldspar concentrate containing 5.72% K2 O, 5.33% Na 2 O, 0.321% Fe 2 O 3 and 0.080% TiO 2 was obtained from a feed containing 5.20% K 2 O, 3.37% Na 2 O, 1.778% Fe 2 O 3 and 0.253% TiO 2 with an overall recovery of 22.4% by weight.

Application of different collectors in the flotation

Jan 01, 2004 The quality of feldspar concentrate (Table 2) measured by the total K 2 O + Na 2 O content was, in all three experiments, approximately the same (12.29%, 12.18% and 12.06% respectively). The content of Fe 2 O 3 in the feldspar concentrate obtained under these conditions in the flotation tests was 0.39%.

A separation process is provided for treating a feed material comprising silica, feldspar, and metal impurities, including at least one of mica, iron impurities, or refractory heavy minerals, to form one or more products for use in making glass. In the process, the feed material is floated in the presence of a depressant to inhibit the flotation of feldspar and thereby form a concentrate

Amine–oleate interactions in feldspar flotation

Jan 01, 2006 Flotation tests show that the amine concentration ought to be kept lower than 1.47 × 10 −5 mol/l (≈5 ppm) to prevent feldspar loss during metal-oxides flotation stage and hence dewatering/washing operation after mica flotation seems to be a crucial step.

Effects of Ultrasound on Desliming Prior to Feldspar Flotation

When the flotation products after ultrasonic pre-treatment were investigated, it was seen that the feldspar concentrate from the sample U1 contained 9.01% Na 2 O, 0.19% Fe 2 O 3, 0.15% TiO 2 and 0.47% MgO while the concentrate by conventional flotation yielded 8.40% Na 2 O, 0.23% Fe 2 O 3, 0.18% TiO 2 and 0.36% MgO.

Developing Effective Separation of Feldspar and Quartz

The results from flotation tests show that the Na 2 O and K 2 O grade of the feldspar concentrate is 10.24% and 0.29% after HF pretreatment, respectively. Meanwhile, the HF pretreatment can separate the feldspar and quartz at pH 2.

Processing Spodumene by Froth Flotation for Lithium Extraction

Mar 19, 2017 Pegmatite ores containing spodumene always contain several other minerals such as mica, feldspar, quartz, and iron and other silicates that have a tendency to concentrate with the spodumene. Weathering and surface oxidation of the rock also give rise to alteration products that interfere with flotation.

Introduction of feldspar beneficiation process

Feldspar minerals are formed uniformly and have stable quality. Potash feldspar and albite account for about 50-60%. Gangue minerals mainly include quartz, mica and iron-containing minerals. Generally, this type of ore deposits need to be processed by flotation to obtain feldspar concentrate. The main processes of beneficiation principles are:

Feldspar Mineral Processing ArrMaz

Feldspar ore is the main source of feldspar mineral concentrate or purified feldspar used in the manufacture of various grades of glass and ceramics including high-end ceramics and electronic-grade glass fibers. The glass and ceramic industries, in particular, are major consumers of feldspar, accounting for 95% of total consumption.
