During its mining, the Únanov-Tvořihráz deposit was considered a source of feldspar-bearing kaolin raw material because the waste after the kaolin processing is a material rich in feldspar grains . The present potential of these deposits is uncertain, and their evaluation would require further geological prospecting.
Feldspar is the name given to a group of naturally occurring alumino-silicate minerals containing varying amounts of potassium, sodium, calcium, and/or lithium. The feldspar group of minerals is by far the most abundant group of minerals in the Earth's crust, making up about 50% of all rocks. Feldspar minerals are essential components in ...
In order to ensure the long-term availability of feldspar and quartz resources, the separation process of quartz and feldspar should be optimized to efficiently utilize these minerals. Since feldspar and quartz are often symbiotic minerals, it is necessary to effectively separate these two minerals when sorting. The following will introduce the …

The feldspar storage is approximately 10 billion tons worldwide, mainly occurring in North America, Europe, and East Asia (Zhang, 2013). Take for example a typical feldspar deposit in Altay, NW China, where feldspar, including sodic plagioclase and K-feldspar, is the main mineral in pegmatites and. Mineral processing of feldspar …
The mining of feldspar is commercially viable because of its numerous uses. There are many companies in Nigeria that engage in the extraction, processing, and production of this mineral such as Stonehill Nigeria Limited, Onshore Frontiers Limited, and a lot more.
The economic analysis of this flotation process is based on the results of quartz and feldspar market research in Jingdezhen City conducted by Jinfeng Mining Co., Ltd in early 2023. The reagent cost analysis for the flotation process in this study and the flotation process with fluorine and acid is shown in Table 4 .

Feldspar is one of the most abundant minerals in the earth's crust. The feldspars include a range of compositions with the general chemical formula xAl(Al,Si) 3 O 8 where x can be sodium (Na) and/or calcium (Ca) and/or potassium (K). The sodium and potassium-enriched compositions are known as alkali feldspars, which are primarily used in glass …
