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.
Feldspar is a kind of silicate minerals that contains calcium, sodium and potassium, there are many categories of Feldspar including albite, anorthite, etc. Feldspar mining process mainly applying the flotation process, and Feldspar mining machines mainly including jaw crusher, ball mill, spiral chute, and concentrating table, etc.

Most of the production from the MacDonald Feldspar Mine had came from the North face of the open pit.
MINROM recently reviewed a feldspar project from an old historical mining project situated in the Limpopo Province of South Africa. The mine focussed on the extraction of feldspar from a large zoned feldspar-mica pegmatite body. These historical mining operations involved a combination of open-pit and underground mining methods.

Aug 04, 2019· The quality of the “spar” decreased and the danger of mining increased, Lowell Presnell writes in “Mines, Miners and Minerals,” and the McKinney mine ceased operation in the 1950s
When Feldspar is mined its done from large granite amounts. The most common procedure in mining feldspar is blasting, drilling, and drop-ball done at a quarry, dividing and fine grinding in jaw crushers, cone crushers, vibrating feeders and rod mills. How is Feldspar processed Two ways of processing feldspar, being crushing and grinding.
Feldspar placer is inferior to pegmatite feldspar deposit in quality, but because the crushing and grinding operations are neglected in the mining and processing process, the cost of ore processing is relatively low, and it is also one of the important sources of feldspar concentrate at present.
Apr 29, 2017· Mining operations at this historical feldspar property were rather reported to have been continuous within that time of acquiring this property. Much of the Feldspar that came from this mine was taken from an open-cut, which was 100 feet long, 12 feet wide, and 25 feet deep. Production during that time of operating this property had amounted to

Mine Limpopo Province. We are the largest open-cast miner of Pegmatite Ore in Africa. Mined ore is washed and sorted into 3 constituent minerals
Feldspar Feldspar was first mined in North Carolina in 1911 in the Spruce Pine district, the main feldspar-producing district in North America. Original mining was from pegmatite bodies but current mining is from alaskite,a very coarse-grained, light-colored, feldspar-quartz-muscovite rock.

feldspar Feldspars are a group of rock-forming tectosilicate minerals that make up about 41% of the Earth’s continental crust by weight. Feldspars crystallize from magma as veins in both intrusive and extrusive igneous rocks and are also present in many types of metamorphic rock.
The feldspar mining operation uses the conventional open-mining system whereby the overburden is removed by bulldozer or backhoes followed by drilling and blasting. Crushing is then carried out with a jaw or cone crusher after which screening through different apertures are done such as 5mm or according to market requirement.
