Chemical formula of galena
In 1973, another study found that chemical analysis of garnierite samples yields non-stoichiometric formulae that can be reduced to formulas like those of talc and serpentine. The authors suggested a talc monohydrate formula of (Mg,Ni) 3 Si 4 O 10 (OH) 2 ·H 2 O for the talc-like garnierite. A third study found Mg, Si, Fe, Ni and Al in the ...Galena is the primary ore mineral of lead. Worked for its lead content as early as 3000 BC, it is found in ore veins with sphalerite, pyrite, chalcopyrite, tennantite-tetrahedrite, etc. and in skarns, as well as in sedimentary rocks where it may replace carbonate beds or be deposited in pore spaces. The crystals are bright when fresh but often ...Expert Answer. Galena is a major lead ore mineral and has the chemical formula Pbs. What is the percentage of lead in galena?
