PROCEDURE FOR DETERMINATION OF GOLD IN ORE AND CONCENTRATES |
摘要 |
FIELD: metallurgy. ^ SUBSTANCE: procedure for determination of gold in ore and concentrate consists in oxidising burning and in successive cinder melting with fluxes, oxide of lead and reducer for production of gold-lead alloy. Further, there is performed cupellation, and gold bead extraction and weighting. Also, oxidising burning is performed with addition of oxide or peroxide of calcium or barium at amount of 110-130 % of stoichiometric required for binding sulphur into sulphate of calcium or barium at temperature 400-700C during 30-60 minutes. Produced cinder is melted for production of gold-lead alloy. ^ EFFECT: more accurate determination of gold. ^ 1 tbl |
