There are several steps in the mining process of Platinum, the first one being extraction of the Platinum ore and bringing it above ground, there are two ways of doing this the first and older way is to blast the ore free with explosives. The second way is to use drilling equipment to remove the ore, this is then transported away to Platinum ...

The Mining Process. Gold at Macraes is known as 'refractory ore', which means it is ultrafine and resistant to the typical cyanide leach process. The mining process at Macraes is circular and follows a cycle of exploration, mining, processing and rehabilitation and closure. With a 30year history of development spanning fluctuating gold ...

With this flow configuration a large portion, approximately 70%, of the gold and silver dissolved in the grinding circuit will flow via the thickener overflow directly to the precipitation circuit. The four meter diameter x meter high leach tanks are sized for a total retention time of 48 hours at 45% solids.

The gold mining operation stage represents the productive life of a gold mine, during which ore is extracted and processed into gold. Processing gold involves transforming rock and ore into a metallic alloy of substantial purity known as doré typically containing between 6090% gold. During its life, a number of factors such as the ...

this mining operation. The process is currently unprofitable with a gold price around 300 per ounce. Process Description 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 tons/hr of gold ore from a feed range of 25" to 160 microns.

Heap Leaching Flow Chart Incorporating Agglomeration into the Heap Leaching Process. The agglomeration of the fines in the heap leaching process allows for enhanced, even percolation of a heap. If left untreated, smaller fines can accumulate in the spaces between larger particles, inhibiting flow of the leaching solution (see figure 2).

Carbonin leach (CIL) is a simultaneous leach and absorption process. The simultaneous leach and absorption phases of the CIL process were developed for processing gold ores that contain pregrobbing materials such as natural absorptive carbon. These reduce the gold yield by attracting gold meant for the activated carbon.

Gold flotation. Flotation process is widely used for lode gold processing. In most cases, the flotation method has a good effect in sulfidecontaining gold ore with high floatability. In addition, the flotation process is also used for polymetallic goldbearing ores such as goldcopper, goldlead, goldcopperleadzincsulfur ore.

Gold mining was first carried out in alluvial areas. Processing system is also very simple to do that is by panning using a tray, which then developed with gold mining wave table, and followed by gravity separation method using the amalgamation process with the capture of mercury.

Step #9 Mine reclamation. After a few years, gold reserves in the mine will be exhausted. In the old days, the mine would be boarded up and abandoned. Today though, a reclamation project is done to try and return the land to its previous natural state as much as possible anyway. As you can see, the process of taking metal ore from the ...
