The head grades of the two ores tested are provided in Table 1, and the modal analysis is given in Table 2. The data indicated that both ores were predominantly nonsulphide gangue. Ore A had about twice as much - gold as Ore B, and contained significantly more pyrite (that is, 3.2% compared to 0.1%). Both ores contained trace levels of copper.

Hydrometallurgical Processing of Gold Ore | Journal of The …

The gold grade in the original ore, calculated from the dough balance, is 2.07 g/t. The gold in the ore is mainly distributed in large grades, so more than 60% of the metal is in the + 1 mm grade. Due to the fact that the bulk of gold in the ore is concentrated in large grades, there is a high probability of finding unopened metal in it.

Gold Refinery Process: From Raw Material to Pure Gold

Gold smelting is an essential process in the journey from raw material to pure gold. Smelting is the process of heating and melting the gold concentrate to separate it from other impurities and achieve a higher level of purity. This crucial step plays a significant role in transforming the gold concentrate into a more refined and usable form.

Refractory gold-ores are characterized by low gold recoveries in direct cyanide leaching. The reasons for low recovery are sulphides, carbon or arsenic due to encapsulation or absorption effects. Oxidizing roasting of such ores prior to leaching is an effective step to increase gold recovery typically to levels well above 90%.
