Cyanidation is use sodium cyanide solution to soak finely ground ore particles, so that the precious metals are dissolved into solution then use activated . their processes basically include the following steps: (1) from the cyanide pulp or solution with activated carbon adsorption leaching of gold, production (3) the use of a.
In the field of Copper metallurgy, we can design production line according to different Copper ore specification and customer requirement. . At the existence of Na2(SO3)2 and NaOH, Ag will dissolve into solution as Ag (SO3)23 , while Au, Pb, Pt, Pd stay as leaching residue which will go Pb separation process later. The Ag.
