There are a few theories on how gold originated but the main consensus is that the majority of gold nuggets originate from Primary gold deposits.
Eluvial gold disintegration of rock at the site where it originates - not there through water movement
are essentially primary gold broken down by weathering and erosion and transported by gravity or water movement over many millenia of geological time.
The landscape of Western Australia was very different millions of years ago, in fact, prospectors would be thankful that the changes over geological time have exposed so much primary ore lodes in Western Australia.
Constant weathering, geological upheavals, redeposition of material in the WA ancient landscape over the millions of years has lead to amazing opportunities to find gold in this state for the modern knowledgeable Gold prospector.
What does all this mean - basically where you find gold, or where it has been found in the past is a good indication of further gold that can be found in that area.
It is important to understand and interpret the gold you find and the local geological environment so you can try to determine what type of gold it is, whether it is alluvial gold or eluvial gold and how it got to the spot where you found it.
These are clear Red Flashing Light signals to you that there may be a primary source of gold nearby.
Alluvial Gold and Eluvial Gold - The Important Differences That May Lead You to the Motherlode
Introduction alluvial gold mining is means mined from land surface or river or underground. JXSC gold mining machine suit for various types of gold raw material alluvial gold placer gold sand gold river gold gold tailing, etc. The main gold processing includes feeding, washing, sieving, rough separation, final concentration, and refining. Because the gold density is much bigger than other minerals, so mainly use gravity separation.
Feeding have various kinds of feeding way, depends on the plant and material conditions . have choices of vibrating hopper feeder, hopper, industrial conveyor belts, or wheel loader and excavator feed directly. Usually will make some grizzly bar on feeding machine or hopper to remove big waste stones
Washing this process is for wash clean the clay and mud in raw material, most popular used are gold trommel scrubber washer and gold washing trommel screen.
Gold trommel scrubber is for washing raw material that with much sticky clay, trommel screen is for wash raw material that with no sticky clay.
Sieving after washing, need to sieve out some bigger waste material, the under screen slurry will go to the next machine. This process can use a trommel screen or vibration screen or high-frequency vibration screen.
Primary concentration this process is for rough gold concentration, can use gold centrifugal concentrator or gold jig separator. The concentrated ore from them will go to final concentration machine.
Final Concentration the concentrated ore from jig machine or centrifugal will go to gold shaking table for the gold final concentration, can get high purity gold.
Tailing recovery usually will use a gold sluice box to recovery tailings that coming from centrifugal machine. So can get more gold.
Refining if some customer needs very very high purity gold and need to smelt to the gold bar for sale, they can use a gold smelting furnace to smelt gold dust to a gold bar.
The most effective process flowchart and most suitable process equipment s are always recommended as per customers request and gold ore conditions and process capacity.
