Iko kukosha uye kushandiswa kweiyo mineral bauxite, aluminium ore.

Tenga natural bauxite muchitoro chedu

Bauxites zvicherwa zve sedimentary zvine aruminiyamu yakawandisa. Ndiyo inonyanya kukosha yealuminium uye gallium munyika. Dombo racho rinonyanya kuumbwa nemaminerari ealuminium, gibbsite, boehmite uye diaspore, yakasanganiswa nesimbi mbiri oxides, goethite uye hematite, iyo aluminium mineral kaolinite uye shoma shoma yeanatase uye ilmenite.

kudzidziswa

Zvirongwa zvakawanda zvekuisa bauxite zvakarongwa.

Vadász (1951) anosiyanisa latitic (silicate) ores kubva karst bauxite (carbonate):

• Carbonate bauxites inonyanya kuwanikwa muEurope, Guyana, uye Jamaica pamusoro pematombo ecarbonate (limestone uye dolomite), kwaakaumbwa nemamiriro ekunze ekunze uye kuunganidza kwakasara kwevhu - ivhu rakapararira - iro rakanyungudutswa sezvo maramu eraimu ainyungudika zvishoma nezvishoma panguva yemakemikari. weathering.
• Matombo ekupedzisira anowanikwa kunyanya munyika dzinopisa. Iwo anoumbwa neperitization yeakasiyana silicate matombo akadai segranite, gneiss, basalt, syenite uye schist. Kuenzaniswa ne-iron-rich lateites, kuumbwa kwematombo aya kunotonyanya kutsamira pamamiriro ekunze akanyanya munzvimbo ine mvura yakanaka kwazvo. Izvi zvinobvumira kaolinite kunyunguduka uye gibbsite kuti iwedzere. Nzvimbo dzine aruminiyamu yepamusoro-soro dzinowanzova pasi pepamusoro pesimbi. Aluminium hydroxide mune latitic deposits inenge yangova gibbsite chete.

Panyaya yeJamaica, kuongororwa kwevhu kwechangobva kuitika kwakaratidza mazinga akakwirira e cadmium, zvichiratidza kuti matombo anobva kuMiocene ash deposits kubva munguva pfupi yapfuura kubva kuzvikamu zvekuputika kwakanyanya muCentral America.

bauxite kubva kuAustralia

Kugadzirwa

Australia ndiyo ine mugadziri mukuru, ichiteverwa neChina. Muna 2017, China ndiyo yaive yakakura kugadzira aruminiyamu, ichiverengera ingangoita hafu yekugadzirwa kwepasi rose, ichiteverwa neRussia, Canada neIndia.

Kunyangwe kudiwa kwealuminium kuri kukura nekukurumidza, nzvimbo dzinozivikanwa dzematombo ematombo dzakakwana kuzadzisa kudiwa kwenyika kwealuminium kwemazana emakore akawanda. Kuwedzera kushandiswa kwealuminium, iyo ine mukana wekudzikisa mari yemagetsi ekugadzirwa kwealuminium, ichawedzera zvakanyanya pasi rose.

Kushandiswa uye kukosha kwebauxite uye kuporesa zvinhu

Kushandiswa uye kukosha kwebauxite

Dombo rinogona kushandiswa mukufungisisa uye rinogona kubatsira nemamiriro ezvinhu angave achikunetsa.

Inogonawo kukubvumira kuziva zvinangwa zvevamwe. Iyo inozivikanwa kubatsira kuwedzera manzwiro ekufara uye kuvandudza kugara zvakanaka.

Iyo haiite ipapo ipapo, asi kana ikachengetwa pedyo, simba rayo rinoshanda sechinhu chinokurudzira nekufamba kwenguva.

Nekubatsira kuti usunungure nyaya dzepfungwa dziri kukutadzisa kuzadzisa zvaunoda, zvinogona kukubatsira kuburitsa manzwiro anokushatirisa kana kutsamwira mamiriro ehupenyu.
