| Abstract: | On the basis of the metallurgy of nonferrous metals,the technology of
direct refining of cyanide goldslime initiates the operation of controlled electric potential in
whole technological course,carrying out successfully the secondary separation of base metals
from precious metals.As a result,the removing rates of base metals as Cu,Pb,Zn come to more
than 99%,the gold content of solution is lower than 1g/m3,the purity of high quality gold and
silver bullions produced directly all come to over 99.9%,the direct recovery rate of Au is greater
than 99% and the synthetic recovery rate of Au and Ag is more than 99.95% |
