Feldspar imwe yemaminerari akajairika mukondinendi crust.Zvikamu zvaro zvikuru zvinosanganisira SiO2, Al2O3, K2O, Na2O zvichingodaro.Iine potassium, sodium, calcium uye shoma shoma ye barium uye mamwe alkali simbi kana alkaline pasi simbi.Seyakarongeka isiri-metallic mineral resources, feldspar zvicherwa zvakaparadzirwa zvakanyanya pasi pevhu, uye ndiyo inonyanya kugoverwa silicate rock-forming minerals kunze kwequartz.Inenge 60% yavo inoitika mumatombo magmatic, 30% mumatombo emetamorphic, uye 10% mumatombo e sedimentary, ane huremu hwose hwe50% yehuremu hwose hwepasi.Kune isomorphism yakagadzirwa zvakanaka mu feldspar minerals, uye kemikari. kuumbwa kunowanzo kuratidzwa naOrxAbyAnz(x+y+z=100), apo Or, Ab uye An inomiririra zvikamu zvitatu zve potassium feldspar, albinite uye calcium feldspar, maererano.
Kunyungudika kwefeldspar kunowanzoita 1300 ℃, density inenge 2.58g/cm.3, Mos kuoma 6.5, iyo chaiyo giravhiti inochinja-chinja pakati pe 2.5-3, brittle, compression kuramba, yakanaka grindability uye kukura kuita, nyore kupwanya.Good kemikari kugadzikana, ngura kuramba, kunze kwepamusoro sulfuric acid uye hydrofluoric acid;Inobatsira kunyunguduka basa, inowanzoshandiswa se flux mu ceramic uye girazi indasitiri;Low index of refraction and birefraction.Ine girazi rinopenya, asi kazhinji ine ruvara rwakasiyana nokuti ine tsvina.Mazhinji emaminerari efeldspar anoshandiswa sezvigadzirwa zvegirazi uye ceramic industry, uye inogona zvakare kushandiswa pakurapa fetireza, abrasives uye maturusi, girazi faibha uye mamwe maindasitiri.
02 Zvinhu zvinokanganisa feldspar mhando
Chekutanga ndicho chinhu chine kugona kudhaya, senge Fe, Ti, V, Cr, Mn, Cu, nezvimwe.
Mumamiriro ezvinhu akajairwa, Fe neTi ndiwo makuru ekudhaya zvinhu, zvimwe zvinhu zvirimo zvidiki kwazvo, chena dhigirii haina pesvedzero.
Chikamu chechipiri iminerari yakasviba, yakadai sebiotite, rutile, chlorite uye zvichingodaro. Zvinyorwa zvemaminerari erima mumamineral rocks zvakaderera, asi zvine simba guru pahutano hwe feldspar concentrate.Rudzi rwechitatu ndiyo organic carbon deposited with feldspar, iyo inopa ore grey-black color.Muzhinji, iyo organic kabhoni iri nyore kubviswa pakupisa kwepamusoro, uye kuchena kune zvishoma.Zvinhu zvikuru zvezvigadzirwa zveindasitiri isimbi, titanium, uye iron, uye pamusoro pechigadzirwa chichaonekwa mavara matema, iyo calcium yemukati yakanyanyisa, pamusoro pechigadzirwa hachina kuenzana, saka kuvandudza kunaka kwemaminerari ematombo akareba, kushandiswa kwedombo refu, zviri mukati memaminerari akasviba uye. calcium inofanira kuderedzwa, kunyanya kubviswa kwe iron oxide.
Kuvepo kwesimbi mufeldspar kunonyanya kuve nemhando dzinotevera: 1. Inonyanya kunzi monomer kana kuti aggregate yehematite, magnetite uye limonite ine particle size ye> 0.1mm.Iine spherical, tsono-yakafanana, inoputika kana isina kukwana, yakapararira zvikuru mumaminerari e feldspar uye iri nyore kubvisa.Chechipiri, pamusoro pefeldspar yakasvibiswa ne iron oxide nenzira ye seepage, kana pamwe nekuputika, minerals uye cleavage joints ye feldspar. kupinda mukati, iyo iron oxide inoumbwa nedhayi yesimbi inowedzera zvakanyanya kuoma kwesimbi kubviswa.Chechitatu, iripo muchimiro chesimbi-inotakura gangue minerals, yakadai sebiotite, limonite, pyrite, ferrotitanium ore, amphibole, epidote uye zvichingodaro.
03 Inowanzo shandiswa nzira dzekubatsira dzefeldspar ore
Parizvino, iyo huru nzira yekuyerera kwemumba feldspar ore kucheneswa kunowanzo "kupwanya - kugaya kupatsanurwa - kupatsanurwa kwemagineti - flotation", maererano neyakasiyana feldspar mineral utsvina yemukati uye gangue mineral embedded maitiro, uye kupatsanurwa kwemaoko, deudging, classification uye mamwe mabasa.
(1) kupwanya nekukuya
Kupwanya kwefeldspar kwakakamurwa kuita hutsinye hwekupwanya uye kupwanya kwakanaka.Mazhinji ores anofanirwa kupinda mukati memaitiro maviri ekupwanya kwakakasharara nekupwanya kwakanaka.Kupwanya kwakawanda kweshaya, kupwanya michina inonyanya kukanganisa mhando crusher, sando rudzi crusher, impact type crusher, nezvimwe.
Kukuya kwefeldspar kunonyanya kukamurwa kuita kugaya kwakaoma uye kunyorova.
Kubudirira kwekukuya kwemvura kwakakwirira kudarika kukuya kwakaoma, uye chiitiko che "kunyanya-kugaya" hachisi nyore kuoneka.Midziyo yekukuya inonyanya bhora, rod mill, tower mill, sanding mill, vibration mill, airflow mill, nezvimwewo.
(2) Kuwacha nekubvisa
Feldspar ore iri mukuita kuumbwa kwakawanda kana kushoma ichange iine imwe nhanho.Kugeza kunonyanya kubvisa tsvina yakaita sevhu, madhaka akanaka uye mica mu feldspar.Kugeza kunogona kuderedza zviri muFe.2O3mune ore, uye zvakare kuvandudza zvirimo zveK2O uye Na2O.Ore washing ndeyekuparadzanisa kubva kune yakakora-grained zvicherwa pasi pekuita kwekuyerera kwemvura nekutora mukana wehunhu hwediki diki saizi uye kunonoka kugadzika kumhanya kwevhu, madhaka akanaka uye mica.Iyo inowanzo shandiswa ore yekuwachisa muchina wekukwesha, vibrating screen uye ore washing tank.
Chinangwa chikuru chekubviswa kwedhaka ndechekubvisa marara ekuzvarwa kubva kune ore uye yechipiri ore yepakati yepakati yekuputsika kwekukuya, uye kudzivirira kuitika kwekutevera kusarudzwa kwehupfu.Iyo inowanzo shandiswa deputer midziyo ine hydraulic cyclone, classifier, centrifuge uye depuff.
(3) kupatsanurwa kwemagineti
Uchishandisa mutsauko wemagineti pakati peakasiyana ores, nzira yekubvisa iron pasi pekuita kwekunze kwemagineti inonzi magnetic separation.Feldspar haina magnetism, asi Fe.2O3uye mica mufeldspar ine magineti asina simba, saka pasi pemamiriro ekusimbisa ekunze magineti, Fe2O3, mica uye feldspar inogona kuparadzaniswa.Parizvino, iyo inowanzoshandiswa yemagineti yekuparadzanisa midziyo muChina inonyanya kusanganisira isingawanzo pasi pasi roller magnetic separator, permanent magnet drum. remagineti separator, rakanyorova remagineti ndiro remagineti separator, yakatwasuka mhete yakakwira gradient magineti separator, electromagnetic slurry yakakwira gradient magineti separator uye superconducting yakakwirira kusimba magineti separator.
(4) flotation
Flotation nzira inoreva kuwedzera kweanogadzirisa mumiriri, muunganidzi, anopupuma mumiriri uye mamwe maajenti mukukuya mbishi zvinhu pulp, kuitira kuti tsvina yesimbi inonamirwa nebubble, kuitira kuti iyo uye pulp mhinduro, uyezve mechanic kukwesha kunze, kuti. iyo tsvina yesimbi uye yakasvibirira yakasvibiswa poda separation.Flotation inzira inobatsira yekubvisa tsvina yefeldspar.Kune rumwe rutivi, inogona kubvisa tsvina yakadai sesimbi uye mica, uye kune rumwe rutivi, inogona kuwedzera zvinyorwa zve potassium uye sodium.Kana iyo mineral yakasiyana, sarudzo yekutora mumiririri yakasiyana, asi reverse flotation process. inogona kugamuchirwa.
