Hand-selected Method Of Spodumene Beneficiation

The sorting of particle size is generally 10 to 25 mm

, determine the minimum size sorting, depending on economic efficiency.

Hand-selected produce lithium ore beneficiation methods used in the earliest history of the United States early in 1906 on the use of this method from the South Dakota Black Hills region pegmatite deposits in the production of spodumene concentrate. In addition to spodumene, but also hand-selected for the production of lithium mica, feldspar through the lithium, lithium phosphate rock, lithium aluminum ore.

U.S. South Dakota Black Hills area is the first U.S. lithium mining mining, has hand-selected method from the selected pegmatite minerals spodumene concentrate, and sometimes with recovery of some of the mineral feldspar, and heavy metals.

Black Mountain a deposit containing Li2O 1.5% ~ 1.7%, mainly by the mineral spodumene, quartz, feldspar, albite, muscovite, apatite and tourmaline components. 1948 hand-chosen selection method was 10.5% of the production of spodumene concentrate grade of 4.8% Li2O, the recovery rate of 30% to 40%, due to low economic efficiency, the reform of the process plant in 1949, 3.3 ~ 38 mm grain size to switch to heavy media beneficiation, 38 to 300 mm size fraction of ore are still hand-selected to remove waste rock.

Chinas 50 years in a mine and three mines in Xinjiang has been hand-selected production of spodumene concentrate, ore containing 1.5% ~ 1.8% Li2O, hand-picked concentrate grade 5% ~ 6% Li2O, 20% to 30% recovery rate.

Hand-picked law because of labor-intensive, low productivity, poor mineral indicators, a large waste of resources, has been generally replaced by flotation or other methods, but in the areas of cheap labor, is still a hand-picked from the coarse cloth embedded lithium ore production of lithium concentrates in important ways.

With its high quality products such as Cement production lineBall millMagnetic separatorHenan Hongxing mining machinery Co.Ltd has ascended in the front rank of the world in the exporting of mining equipments.
