  • How is Sodium Cyanide Consumed during Gold

    5.Cyanide Adsorption by Slime. The iron sulfide in ore will produces ferric hydroxide during cyanidation process. The silicate of ore forms colloidal silicon oxide in an alkaline medium. They all have a certain adsorptionbility for cyanide, so that the cyanide will lost along with the leaching residue. 6.Consumption of Cyanide by Other Materials

    2014-6-19 · This paper is a brief overview of the role of inducing the nucleated electro winning of copper by using iron electrodes in electrocoagulation (EC) process. Cyanide compounds are widely used in gold ore processing plants in order to facilitate the extraction and subsequent concentration of the precious metal. Owing to cyanide solution employed in gold processing, effluents generated have high

  • Should cyanide still be used in modern-day mining?

    Additionally, the cyanide-free biocatalyzed leaching process from YES Technologies, is said to be 200 times less toxic than cyanide. All three of these alternative gold separation processes are fairly nascent technologies and not as cheap or well-established as cyanide, although they could be serious contenders as a replacement in the future.

  • Cyanidation of a copper-gold ore ScienceDirect

    1997-8-1 · The Sceresini process and the ammonia/cyanide leaching process have reached commercial scale in the recent years (Zheng et al., 1995), while efforts are still underway for the development of thiourea and thiosulfate leaching processes. Thiourea leaching of a copper-gold ore showed moderate success (Lacoste et al., 1996).

  • leaching cyanide process gold extraction

    This process of dissolving the gold using cyanide is known as leaching. Sometimes some other precious metals can also be leached along wit. h the gold, for example silver. This process of leaching is done in leaching tanks or by heap leaching where sodium cyanide is dripped onto a heap of gold ore and left to percolate its way.

  • Ore processing Waihi Gold

    Ore is stockpiled (1) at the processing plant, and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed, and lime is added (2) to raise the pH of the ore. Following crushing through a jaw crusher (3), the ore is fed into the semi autogenous grinding (SAG) mill (4)
