On the basis of study on the ore property ofmagneticores containingapatite,The experiment results show that amagneticconcentrate having a recovery of 58.04%,a concentrate containing 60.38%Fe and yield of 10.90% after by means of two-stagesmagnetic separationat a grinding fineness of 75%-200 mesh of the first stage , grinding fineness of ...
Aug 01, 1988· The beneficiation ofapatitefrom low grademagnetite-apatiteore was studied.Wet magnetic separationfollowed by flotation was found effective. The effects of different grinds, pH, depressants and collectors at varying dosages were investigated.
A wet high-intensitymagnetic separatorwas used to remove iron bearing minerals. As results, 71% of iron was separated into themagneticfraction from the iron richapatitesample, while 92% of...
Magnetic separationtakes advantage of naturalmagneticproperties between minerals in feed. Theseparationis between economic ore constituents, noneconomic contaminants, and gangue.Magnetiteand ilmenite can be separated from their nonmagnetic rock-forming minerals of host rock as valuable products or as contaminants.
It is clear that the specificity and affinity of the Fe 3 O 4 @Cu-apatite NPsremained unaffected after recycling 4 times. Theseparationefficiency was respectively 97.1%, 92.3%, 90%, and 85.7% for four operation cycles, indicating that the Fe 3 O 4 @Cu-apatite NPshave excellentseparationefficiency. Fig.
For samples with excessive nonmagnetic sulphiderequiringelectrostatic separationof the zircon concentrate add $10 per sample *standard sample – granitoid or hard rock, 1 Kg or less, without excessive amounts of nonmagnetic sulphide(see above)
The only problem is, if you have very rare and small grains of zircon in sediment. Then I would suggest to make heavy liquid - bromoform separation first and to apply hand-picking only on obtained small quantity of heavy fraction (separating zircon from pyrite and the rest heavy minerals).
The beneficiation ofapatitefrom low grade magnetite-apatiteore was studied. Wetmagnetic separationfollowed by flotation was found effective. The effects of different grinds, pH, depressants and collectors at varying dosages were investigated. Various process parameters were optimized and the rougher concentrate was cleaned thrice for improvement in theapatitegrade.
Magnetic Separationas a Process . Where applicable, this process possesses all the advantages held by otherseparationprocesses, and, in addition, is independent of gravity. A prerequisite of success in anyseparationprocess is the existence of the minerals to be separated as free particles, and in thismagnetic separationconstitutes no ...
Electricalseparationis used frequently withmagnetic separationand gravityseparation. Flotation can be used for eliminate silycates out of the iron concentrate. Next effects exist in nature:
Apatiteminerals are readily floated using anionic collectors such as fatty acids. At LKAB (Luossavaara-Kiirunavaara AB) in Kiruna, Sweden, the dephosphorization of a magnetite ore is conducted usingmagnetic separationand flotation. In the flotation process, theapatiteminerals are floated with a fatty acid based collector.
Apatiteis mostly used for fission track dating (thermochronology). Frantzmagneticseparator:Magnetic separationis based on minerals`magneticproperties. Some of the largest andmagneticminerals (ferromagnetic minerals) are often removed via a handheld magnet before they are sent through themagneticseparator.
The first commercial production of phosphate rock began in England in 1847. A wide variety of techniques and equipment is used to mine and process phosphate rocks in order to beneficiate low-grade ores and remove impurities. The eighth chapter of this book deals withmining and beneficiation of phosphate ore. The principle and operating conditions of important parts of manufacturing process ...
The ore dressing of non-ferrous metal ore, such as copper, lead, zinc, sulfur, molybdenum and other mines, is mainly treated by flotation; some ferrous metals, rare metals and some non-metallic ores, such as graphite ore,apatite, etc. are also used for flotation.Magnetic separationmethod
