Leaching of a silver bearing sulphide by-product with cyanide, thiourea and chloride solutions

open access: yes, 1995
The aim of this research was to increase the value of sulphide tailings assaying 1000-1500 g/ton Ag per tonne and high arsenic (about 13%) content. The sulphides were characterized and it was verified that silver occurs both as mathildite, AgBiS2, and in

Noncyanide leaching of an auriferous pyrite ore from Ecuador [PDF]

open access: yes, 2000
journal articleGold leaching of an auriferous pyrite ore from the Portovelo deposit in Ecuador indicates that noncyanide leaching systems, such as thiocyanate and thiourea, are not as effective as the traditional cyanide system.
