cyanide leaching of gold - mine engineer

arsenic and antimony do present a larger problem by reacting with the cyanide and using up all of the excess oxygen leaving little or no oxygen to effect the dissolution of gold carbonaceous gold ores can have the carbon adsorb the gold onto its surface and as a result will not be recovered from the pregnant solution

how arsenic affects cyanidation leaching of gold - metallurgist

mar 18 the influence of arsenic in the cyanidation of gold ores is explained by w b blyth has he is of the opinion that the presence of arsenic in an ore does not necessarily cause that ore to be refractory to cyanide treatment he thinks the idea arose from the fact that arsenic is so often accompanied by antimony
