2019-6-28 Once the gold ore has been removed from underground and brought to surface, an entirely new challenge begins in separating the gold from the waste material. The separation process is particularly difficult due to the usually low quantity of gold relative to waste. Common gold grades are in the same magnitude as about 5 g/t, or 0.000005% gold ...

The work of Freer , following on from Bohme and Kilian , showed how successful this route is for optimizing the mill power draw and throughput of a gold ore mill. Given the breakage characteristics of most ore waste systems and widespread use of autogenous and semi-autogenous mills, the potential for this type of sorting appears enormous.

When separating waste rock, the terms potentially acid generating rock (PAG, or acid forming rock, PAF) and non-acid generating rock (NAG, or non-acid forming rock, NAF) are often used. This classification is further explained in lecture 5. A collection of rocks taken from a waste rock pile.

The process of heap leaching extracts gold from ore by piling up crushed ore and applying a leaching agent to permeate through the pile, separating the gold from the ore. While this method has been used for decades with success, it has been greatly improved by the addition of an agglomeration drum to the process before the heap.

Read MoreMining lower grade ore requires the extraction and processing of much more ore to get the same amount of gold. Partially due to cyanide, modern mines are. much larger than before cyanide was used; create vast open pits; and; produce huge quantities of waste. More than 20 tons of mine waste are generated to produce enough gold for a typical ring.

2016-10-28 In panning large samples, only one or two specks of gold could be seen, although the ore contained from 1 to 2 ounces per ton. This ore yielded only about 40 per cent, on being amalgamated, but over 90 per cent, was dissolved out by leaching the raw ore with cyanide of potassium, and similar results were obtained by chlorination.

Read MoreMercury is also extensively used in the gold mining process as an amalgam for separating gold from ore. When mercury is combined with gold silt, it causes a reaction that separates the gold from the ore. This amalgam is then heated in order to evaporate the mercury and leave the gold pieces.
Read MoreA stark difference in gold ore vs. printed circuit boards (PCBs) is that a rich gold ore might have 0.5 – 1.0 oz of gold per ton of ore, but computer PCBs contain 3 – 8+ oz gold, 15 – 20+ oz silver, 500+ lbs copper per ton of boards, plus multiple other base and precious metals. Given the commodity nature of electronics such as computers ...

Removing the gold-bearing rock from the ground is just the first step. To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel.
