Sulfide mineral deposits originate in two main processes, ob leeg uas muaj txo tej yam kev mob: (1) sib cais ntawm ib immiscible sulfide yaj thaum lub sij hawm thaum ntxov ntawm crystallization ntawm yooj yim magmas; thiab (2) tso tawm los ntawm aqueous brine daws ntawm qhov kub thiab txias hauv 300–600 ° C (572–1, 112 ° F) ntau thiab ntawm …

Sulphide mineralization yog dab tsi?

Cov mineralogy ntawm sulfides yog ntau haiv neeg nyob rau hauv thaum ntxov carbonatite-series pob zeb, tshwj xeeb tshaj yog nyob rau hauv lub cheeb tsam ntawm phoscorites thiab calcite carbonatite, qhov twg sulfides yog tshwj xeeb tshaj yog nplua nuj (kwv yees li 5 vol %).

Sulphate thiab sulfide minerals txawv li cas?

Sulfide (British English kuj sulphide) yog ib qho inorganic anion ntawm sulfur nrog cov tshuaj formula S2- los yog ib tug compound uas muaj ib los yog ntau tshaj S2- ions.… Cov sulfate los yog sulphate ion yog polyatomic anion nrog cov mis empirical SO2-4. Cov ntsev, kua qaub derivatives, thiab peroxides ntawm sulfate yog dav siv hauv kev lag luam.

Sulphate minerals siv rau dab tsi?

Ntau qhov tso nyiaj ntawm sulfate minerals, xws li barite thiab celestite, yog siv rau npaj cov ntsev ntsev Ntau lub txaj ntawm sulfate minerals yog mined rau chiv thiab ntsev npaj, thiab txaj ntawm cov ntshiab gypsum yog mined rau kev npaj ntawm plaster ntawm paris.

Vim li cas sulfides zoo ore minerals?

Qhov tseem ceeb tshaj plaws, cov sulfides yog pab pawg tseem ceeb tshaj plaws ntawm cov ore minerals vim tias lawv yog lub luag haujlwm rau cov concentration ntawm ntau yam hlau raws li mineable deposits. Lawv kuj yog qhov chaw muaj kuab paug, xws li huab cua, dej saum npoo av, lossis av.
