    Unit 100 – Size Reduction of Ore The BFD of the overall process is shown in Figure 1. The PFD for Unit 100, shown in Figure 2, is designed to reduce 41.5 tons/hr of gold ore from a feed range of 2-5” to 160 microns. The mined ore is fed using a Grizzly Feeder, F-101, into a Jaw Crusher, J-101, where 80% of the ore is crushed to 1.75” or ...

    Gold Refining From Gold Ore to Dor 233 World Gold Council

    From ore to dor . More gold is recovered by cyanidation than by any other process. In cyanidation, metallic gold is oxidised and dissolved in an alkaline cyanide solution. When gold dissolution is complete, the gold-bearing solution is separated from the solids. With ores of higher gold content (greater than 20 grams of gold per tonne of ore ...

    The complexity of this processing depends in part on the grade of the ore. Low-grade ore is relatively simple to process while high-grade ore is a more extensive and complicated process. Completing Off-Site Refining; Once the initial processing is done on-site, the gold is transported to an off-site refinery to undergo further refining.

    For materials containing a relatively high concentration of gold or platinum group metals, the ‘inquartation process’ may be employed. In this, the material is melted with additional silver or copper to form an alloy with 25% gold, which is then melted and converted to high surface area grain to facilitate dissolution in nitric acid.

    The amount of tailings generated is dependent on the ore grade, (proportion of valuable minerals in the ore). For example, if the cut-off grade in the ore is 1 % Copper, 99 percent of the total ore would be deposited as tailings. Iron ores generally have higher grades than sulfide or gold ores, often going over 50 per cent or more.
