Northwest Lead And Zinc Smelter Electrolytic Zinc Processing Cost Analysis And Control

The paper anal yses theore tically the material and power consumpt ion in main sequencesof hydro--meta1lurgy of zinc, closely combines the reduction of refining cost ofelectro1ytic zinc. with the process control of the whole zinc hydro-metallurgy (especially with analysis of process technological conditions andphysi--chemistry process), meanwhile puts formrd feasib1e measures for reducingrefining cost of e1ectrolytic zinc in 1ight of nearly three years' productivepractice of the Northwest Leadgyinc Smelter.The paper analyses the smelting process control of main seqUences of zinchydro--metallurgy, analyses and studies measures and means for reducing refining costof e1ectrol ytic zinc from vie' point of sme1ting speciality, closely and orgnnica11ycombines financiaI accounting with smelting specialty so as to kep away from narrowand sing1e ana1ytic mode of the two specia1ities in the past in accordance with threeyeas' refining cost of e1ectrolytic zinc of the Northwest Leadaxinc Smelter.As sost 'of the main adriinistrators of zinc hydro--meta11urgical sme1ters in ourcountry are from smelting special ities, the paper has a certain directive functionto the ddministrators of zinc hydro--metallurgical smelters with their costadrii n istrat ion.
