Barite chofunika, mwachibadwa zikuchitika, mchere barium ofotokoza. Barium, chiwerengero atomiki 56, zichokela dzina la Greek kutanthauza lolemera. Barite imatchedwanso baryte. Mayiko zofunika kwambiri zimene madipoziti malonda barite panopa anapeza ndi United States, China, India ndi Morocco. Barite mkulu osalimba ndi mankhwala inertness kuti zinthu mchere abwino ntchito zambiri.
Mankhwala chilinganizo cha barite ndi BaSO4. Iwo ali mkulu enieni kufunika kwa 4.50 g / cm3. Ake Mohs kuuma ndi 3.0 kuti 3.5. Barite, zomwe zingapezeke yosiyanasiyana kuphatikizapo chikasu, bulauni, woyera, buluu, imvi, kapena ngakhale colorless, ambiri ali ndi vitreous kuti ngale luster.
Barite zingapezeke molumikizana ndi onse zachitsulo ndi madipoziti nonmetallic mchere. Kukhala chuma yotheka kwa m'zigawo, barite zambiri ayenera kukhala nkhani osakhala mu gawo la. Mitundu ya madipoziti umene zambiri zopezeka monga mtsempha, yotsalira, ndipo bedded. Mtsempha ndi madipoziti yotsalira akuchokera Madziwo, pamene bedded madipoziti ndi nyanja.
Major madipoziti mu United States apezeka Georgia, Missouri, Nevada ndi Tennessee. mu Canada, mchere wakhala ncho mu Yukon Gawo, Nova Scotia ndi Newfoundland. mu Mexico, madipoziti barite akhala inapezeka Hermosillo, Pueblo, Monterrey ndi Durango.
Mafuta ambiri a barite omwe amakumbidwa amagwiritsidwa ntchito ndi mafakitale a petroleum ngati chinthu cholemetsa popanga matope.. Barite imawonjezera mphamvu ya hydrostatic ya matope obowola kuti athe kubweza madera omwe ali ndi vuto lalikulu pobowola.. Kufewa kwa mcherewo kumathandizanso kuti asawononge zida zobowola pobowola ndikupangitsa kuti ikhale ngati mafuta.. American Petroleum Institute (API) wakhazikitsa mfundo zogwiritsira ntchito barite pobowola matope.
Dry Barite Beneficiation
STET ali lonse woyendetsa lonse ndi zinachitikira malonda processing barite kuchotsa gangue monga silicates, chitsulo, and alumina. Low-grade barite beneficiation with a specific gravity between 3.5 - 4.0 has been successfully upgraded using the STET process to product API-grade barite.
STET angasonyeze kuti youma electrostatic kulekana ndondomeko amapereka ubwino ambiri pa miyambo yonyowa processing njira (flotation) kuphatikizapo:
Kusokoneza makampani atsopano nthawi zonse kumakhala kovuta. cha ku Switzerland Zida & Technology ndi Ramadas Minerals Pvt. Ltd. ku India kumvetsetsa bwino vutoli. Ramadas Minerals adalumikizana ndi STET kuti achite kuyesa kwa barite otsika / zitsanzo za quartz zopangidwa ku mgodi wa barite wa APMDC ku Andhra Pradesh, India. Zinthuzo zinali zotsika tailings mankhwala kuchokera ndondomeko migodi. Inali ndi silica yochuluka kwambiri kuti ingagulitsidwe ngati chinthu chapamwamba cha SG barite, ndipo anali kupangidwa m’mavoliyumu aakulu. Chomwe chinali chofunikira chinali njira yosinthira zinyalala zamigodi kukhala zogwiritsidwa ntchito. Kunyowa processing (flotation) inali imodzi mwaukadaulo womwe ukuganiziridwa.
Kuyesedwa pa malo oyendetsa STET kunawonetsa zotsatira zabwino zolekanitsa za ufa wa barite. Olekanitsa STET anatha kukwaniritsa cholinga cha +4.20 SG barite kudutsa gawo limodzi lolekanitsa.
Wolekanitsa STET anali woyenera mu nyumba yomwe ilipo, yomwe poyamba idapangidwa kuti ikhale ndi malo oyandama. The STET olekanitsa unsembe zinachititsa kwambiri kupulumutsa malo, mogwirizana ndi malo oyandama omwe adapangidwa kale. Kuphatikiza apo, kutsika kwakukulu kwa ndalama ndi ndalama zoyendetsera ntchito kunapezeka.
Lumikizanani ndi STET kuti mudziwe zambiri za kukonza kowuma kwa barite.
