For determination of total molybdenum in its ores,the sample was heated with HCl and fumed with mixed acid of HNO3 and H2SO4(8+2) to dryness.Instead of the alkali fusion,the residue was treated with 150 g·L-1 NaOH solution to transform molybdenum into molybdate,and content of total molybdenum was determined in the supernatant.For dissolution of different phases of molybdenum ore,a separate sample was first heated with aqueous ammonia to dissolve the molybdite(MoO3),and insoluble residues… CONTINUE READING
