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 ...

Scrubbing is used to remove these impurities of thin film iron and blocking impurities on the surface of quartz. Rod rubbing is an effective way to remove these impurities. The scrubbing concentration can be controlled between 50% and 60%, and the scrubbing time can be determined according to the properties, which can further reduce the ...

Flotation is an effective way to remove impurities in feldspar. On the one hand, impurities such as iron and titanium in feldspar can be removed. On the other hand, the separation of feldspar and quartz can be achieved, thus increasing the content of potassium and sodium.

When the iron-containing impurities in potassium feldspar are pyrite, mica or in the form of iron-containing alkali metal silicate minerals such as garnet, tourmaline and hornblende, the flotation method is mostly used to remove the impurities. The conditions for removing potassium feldspar impurities by flotation are as follows: 1.

2. Potash feldspar flotation process. When the iron-containing impurities in potash feldspar are pyrite, mica, or in the form of iron-containing alkali metal silicate minerals such as tourmaline and hornblende, the flotation method is often used to remove the impurities.

A process of removing iron impurities from ores, particularly useful for removing stains of iron impurities adhered to silica sand particles, comprises grinding the ore, washing and desliming the ground ore to remove the major part of the clay-type binder, attrition-scrubbing the deslimed particles to release further amounts of binder therefrom, washing and desliming to remove said binder ...

The quartz sand flotation method mainly removes iron-containing mineral impurities such as mica, feldspar, garnet and amphibole. A three-stage flotation process is used to remove iron-containing argillaceous, mica and feldspar minerals from quartz sand respectively. The quartz sand flotation method Advantages of the flotation method:

Process for removing iron from rare earth ore. May.31,2021. ... Generally, common mineral impurities in quartz sand, such as silicate minerals such as feldspar and mica, can be removed by flotation process to remove most of the mineral particles other than quartz sand and enrich quartz. ... The quartz sand flotation can not only remove mica and ...

The principal impurities in some feldspar ores are titanium and iron, which impart color and in turn degrade the quality of the ore. Mineralogical investigations on the majority of Turkish feldspar ores indicate that rutile and, scarcely, sphene are the major titanium minerals and iron mainly originates from mica minerals.
