| Abstract: | The swatch was melt with the sodium hydroxide and the sodium peroxide mix melting agent,lixiviated with acid,dryly filtered,prepared into solution in a volume.The silicon dioxide content in the manganese ore was determined by ICP-AES.The standard sample(metallurgy department standard sample 505)was measured by this method with the RSD of 1.08% and the mean content value of 33.93%(recommendation value of standard sample is 33.58%). |
