Feldspar - Minerals Education Coalition

Feldspar is mined from large granite bodies (called plutons by geologists), from pegmatites (formed when the last fluid stages of a crystallizing granite becomes concentrated in small liquid and vapor-rich pockets that allow the growth of extremely large crystals), and from sands composed mostly of feldspar.

11.27 Feldspar Processing - US EPA

A froth flotation process is used for most feldspar ore beneficiation. Figure 11.27-1 shows a process flow diagram of the flotation process. The ore is crushed by primary and secondary crushers and ground by jaw crushers, cone crushers, and rod mills until it is reduced to less than 841 µm (20 mesh). Then the ore passes to a three-stage, acid ...

Feldspar Group: Mineral information, data and localities.

Feldspar is the name of a group of aluminium silicate minerals and is collectively the most common mineral group found on the surface of the Earth. The major rock-forming minerals in the Feldspar group include albite, anorthite, orthoclase and microcline. In petrology the group is split into two major subgroups:

Feldspar - Digitalfire

Notes. Theoretically speaking, the term 'feldspar' refers to a family of minerals with a specific crystalline presence. However actual feldspar powders are made from crushed crystalline rock containing a mixture of aluminum silicates of sodium and potassium (with minor amounts of lithium or calcium). They normally contain 10-15% alkali (K 2 O, Na 2 O) and melt well at …

Feldspar Beneficiation & Flotation Process

Third stage flotation with hydrofluoric acid and amine acetate floats the feldspar and leaves a highly siliceous tailing. The first and second stages may be combined if the mica is not to be recovered. Owing to the diversity in mineral content of feldspar deposits, a separate reagent combination needs to be developed for each.
