2. Feldspar is part of our daily life
Feldspars are primarily used in industrial applications for their alumina and alkali content. The term feldspar encompasses a whole range of materials. Most of the products we use on a daily basis are made with feldspar: glass for drinking, glass for protection, fiberglass for insulation, the floor tiles and shower basins in our bathrooms, and the tableware from which we eat. Feldspar is part of our daily life.
Feldspar is part of our daily life
The quality and value of the products are bound to the content of K2O, Na2O and coloring matter, namely iron and titanium oxides.

3. Three main end-members:
Feldspar is by far the most abundant group of minerals in the earth's crust
Most deposits offer sodium feldspar as well as potassium feldspar and mixed feldspars
Chemically, the feldspars are silicates of aluminium, containing sodium, potassium, iron, calcium, or barium or combinations of these elements.
Three main end-members:
Albite Ab NaAlSi3O8
Anorthite An CaAl2Si2O8
Orthoclase(K-Feldspar) Or KAlSi3O8
Solid solutions between K-feldspar and albite are called alkali feldspar.[2] Solid solutions between albite and anorthite are called plagioclase

4. High-intensity, dry, magnetic separation has been already applied to a variety of ores. In particular, iron, titanium and chromium-bearing impurities are removed from raw materials in the ceramic and glass industries. The removal of mica, tourmaline, and minerals improves the quality of the concentrate significantly

10. Flotation of Quartz
Quartz is a hydrophilic mineral. There are two types of quartz flotation. These are true and reverse
1- True Flotation
Generally cationic type collecters are use.
The pH is 8-10

11. RECOVERY-COLLECTOR CURVE
Fine quartz: µm

12. RECOVERY-DEPRESSANT-FROTHER CURVE

13. RECOVERY-FROTHER-CONDITION TIME CURVE

14. RECOVERY-FROTHERS CURVE

15. Reverse flotation

16. What is Graphite ? Graphite is one of the allotropes of carbon.
Unlike diamond, graphite is an electrical conductor.
Graphite holds the distinction of being the most stable form of solid carbon ever discovered.
It may be considered the highest grade of coal, just above anthracite and alternatively called meta- anthracite, although it is not normally used as fuel because it is hard to ignite

17. Types of Graphite
Amorphous Graphite
Flake Graphite
Vein graphite
