The presence of gold telluride minerals may render an ore refractory, the extent of this depends on the telluride mineral present and the mineralogical association 3. Gold, silver, and gold/silver-telluride minerals in ores dissolve more slowly than native gold in cyanide solutions, which results in less efficient gold extraction 4.

Gold CIL processing plant Carbon in Leach (CIL) process is widely used in the mining industry and in particular, it is an integral step of gold processing in gold extraction. Normally the CIL process can concentrate gold from 2.53.5 g/t in ore to 2000 to 6000 g/t on carbon.
Jan 23, 2012 Step 7 Processing (on-site) Once ore is extracted, processing it into pure gold must be done. Ore is first crushed and then undergoes various processes depending on the nature of associated minerals. Processing low-grade ore is relatively simple while higher grades require more extensive processing. Step 8 Refining (off-site)
