Bauxite hmoovkev loj hlob puag:
Guizhou yog lub chaw tsim khoom tseem ceeb ntawm bauxite nyob rau hauv Suav teb, suav txog li 1/5 ntawm lub teb chaws reserves, uas Qingzhen thiab Xiuwen muaj bauxite reserves loj tshaj plaws thiab qib siab tshaj plaws. Tom qab ua tiav, bauxite tuaj yeem siv los tsim cov cement thiab cov ntaub ntawv refractory, thiab tseem tuaj yeem siv rau hauv kev lag luam aluminium, nonferrous hlau smelting thiab abrasive kev lag luam.
Lub Qingzhen Mage Mine, uas bauxite mining thiab sib sib zog nqus ua hauv paus nyob ntawm, yog mine ntawm Guiyang Refractory Factory. Thaum Lub Rau Hli 2007, ib lub tuam txhab hauv Shenzhen tau ua tiav tag nrho cov cuab yeej ntawm Guiyang Refractory Factory, txoj cai tswjfwm kev lag luam poob nyiaj. Raws li lub hauv paus ntsiab lus ntawm "vitalizing lub Tshuag thiab optimizing qhov increment", lub tuam txhab tau nqis peev ze li ntawm 200 lab yuan los tsim Mage Mine hauv Qingzhen. Nws cia siab tias thaum kawg ntawm xyoo 2009, lub tuam txhab yuav muaj peev xwm tsim tau 404000 tons / xyoo hauv Guizhou, nrog cov nyiaj tau los ntawm kev muag khoom ntawm 310 lab yuan, thiab tom qab ntawd dhau los ua cov khoom lag luam loj tshaj plaws nyob rau sab qab teb ntawm Yangtze River. thiab thaj tsam nruab nrab thiab sab hnub poob ntawm Tuam Tshoj.
Kev tsim kho ntawm bauxite mining thiab sib sib zog nqus ua hauv paus ntawm Guiyang Refractory Cog, nyob rau hauv Maige Township, Qingzhen City, tau pib. Peb cov kab hluav taws xob ua hluav taws xob nrog cov khoom tsim tawm txhua xyoo ntawm 60000 tons ntawm high-alumina clinker yuav tsim los ua qhov loj tshaj plaws bauxite sib sib zog nqus ua hauv paus hauv Guizhou xeev. Guizhou xav kom dhau los ua qhov loj tshaj plaws bauxite sib sib zog nqus ua hauv paus hauv Suav teb.
Keeb kwm ntawm bauxite:
(1) Xiuwen hom carbonate ancient weathering crust allochthonous tsub zuj zuj subtype bauxite deposit, tseem hu ua carbonate ancient weathering crust allochthonous accumulation subtype bauxite deposit. Nws cov keeb kwm muaj feem xyuam rau carbonate karst tom qab huab cua puag thaum ub. Thiab vim hais tias muaj ob peb meters tuab lacustrine hlau lenticular deposit ntawm cov bauxite thiab lub hauv paus carbonate bedrock, cov bauxite tsis tau sau nyob rau hauv situ, tab sis cov tom qab huab cua crust nyob ze ntawm lub pas dej ze ze ntawm lub pas dej qhuav yog migrated thiab accumulated nyob rau hauv ntau qhov chaw. Hom kev tso nyiaj no yog ib txwm ntawm Xiaoshanba bauxite deposit hauv Xiuwen County, Guizhou. Vim hais tias lub hauv paus bedrock yog carbonate pob zeb, aluminium-nplua nuj calcium-laterite eluvial txheej tsim los ntawm huab cua feem ntau hais tias yuav ntev lub sij hawm yaig, uas yog, lub sij hawm ntev huab cua, qhov ntau thiab thicker aluminium-nplua nuj calcium- cov pob zeb hauv av tsim los ntawm huab cua, cov bauxite ntau dua, cov av nplaum tsawg dua, cov qib ore ntau dua, thiab cov thickness ntawm cov ore ntau dua.
(2) Xin'an hom carbonate ancient weathering crust nyob rau hauv-situ tsub zuj zuj subtype bauxite deposit, tseem hu ua carbonate ancient weathering crust nyob rau hauv-situ tsub zuj zuj subtype bauxite deposit, yog ib yam ntawm Zhangyaoyuan bauxite deposit nyob rau hauv Xin'an, Henan. Bauxite ntawm hom kev tso nyiaj no yog ncaj qha them rau ntawm karst yaig nto ntawm carbonate pob zeb, thiab yog khaws cia hauv qhov chaw. Nyob rau hauv ntau zaus, nws yog sau nyob rau hauv karst qhov tsua thiab tov thoob. Lub cev ore tsis ntev (ntau pua meters), tab sis nws tuab yog loj (40 ~ 60m). Yog tias qhov yaig cuam tshuam rau lub sijhawm luv luv, feem ntau tsuas yog calcareous eluvium tsim, nrog me ntsis kev tsiv teb tsaws thiab kev thauj mus los. Txawm hais tias cov ore zoo me ntsis tsis zoo, lub txaj ore yog ruaj khov thiab cov thickness hloov me ntsis.
(3) Pingguo hom carbonate ancient weathering crust nyob rau hauv-situ tsub zuj zuj - niaj hnub karst accumulation subtype bauxite deposit. Nws tseem hu ua carbonate ancient weathering crust in-situ accumululation - niaj hnub karst accumulation subtype bauxite deposit. Lub overlying thiab hauv qab bedrock ntawm deposit yog limestone nyob rau hauv ib tug tuab ntawm pua pua meters. Tom qab Quaternary karst, limestone thiab bauxite ore yog weathered rau tom qab thiab bauxite ore fragments poob mus rau hauv ore ntau. Kev tsim cov xwm txheej ntawm hom kev sib xyaw ore no feem ntau yog: muaj qee qhov teev ntawm cov txheej txheem ore, muaj cov xwm txheej tsim nyog, yuav tsum muaj cov limestone tuab saum toj thiab hauv qab ntawm lub txaj ore, thiab av nplaum shale nyob rau sab saum toj thiab hauv qab. ore txaj yog nyias.
(4) Zunyi hom aluminosilicate ancient weathering crust accumulates subtype bauxite deposit nyob rau hauv situ. Kuj tseem hu ua aluminosilicate ancient weathering crust in-situ accumulation subtype bauxite deposit, the underlying bedrock is fine clastic rock or basic volcanic rock, and is the bauxite deposit of the underlying bedrock lateritized weathering crust in-situ accumulation (ob peb nqes hav deposits). Txoj cai ore-forming txoj cai ntawm hom kev tso nyiaj no yog: thawj zaug, muaj qhov hloov pauv tshwm sim nrog lub hauv paus bedrock, thiab muaj kev yaig tsis tu ncua nrog cov strata overlying, yog li lub thickness hloov tau zoo heev, thiab muaj ntau oreless skylights; Qhov thib ob, lub thickness ntawm lub txaj ore, qhov loj ntawm lub cev ore thiab qib ntawm cov ore nyob ntawm qhov ntev ntawm kev yaig thaum lub sij hawm mineralization thiab seb lub hauv paus hauv paus yog yooj yim weathered. Yog tias qhov yaig cuam tshuam rau lub sijhawm ntev, lub hauv paus hauv paus eroded thiab weathered feem ntau yog pob zeb zoo nkauj, av nplaum shale, thiab tsuas yog ib feem ntawm nws yog carbonate pob zeb. Lub txaj ore feem ntau yog tuab, loj hauv nplai, thiab cov ore zoo yog qhov zoo, tab sis tus naj npawb ntawm cov pob zeb tsis muaj skylights nce. Yog hais tias lub hauv paus bedrock eroded thiab weathered yog weathered basalt, lub ore txaj thickness thiab ore lub cev loj yuav loj, thiab cov ore kuj yuav nplua nuj. Yog hais tias lub hauv paus bedrock yog weathered basalt, tab sis lub sij hawm yaig luv luv thiab huab cua tsis tiav thaum lub sij hawm mineralization, lub thickness ntawm lub ore txaj, qhov loj ntawm lub ore lub cev thiab qhov zoo ntawm cov ore yog tsis yooj yim sua kom tau raws li qhov zoo tagnrho. .
