Trying to gather some ideas for recirculating sluice water. Of course my issue is muddy water. This increases the water viscosity and less very fine gold will drop out of the flow. Just wondering what tricks others may have tried that worked. I don't have a couple of 1000 litre tanks or a settling pond.

Glot, may have a solution, you may even know what I'm talking about. A long time ago on a friends dairy farm, he showed me a flow through filter they use to remove all the dirt out of the system now I'm not sure if the filter is used for the milk or water. But when i was shown dirty water from a puddle was used, with in the foot also long filter sock the dirty water come out at drinking quality so they say but it was clear and I couldn't see any Merck to it. Maybe worth a search they are a disposable filter and from memory they are only few dollars each well 15years ago now but the idea is there to explore.

Any filtering material would clog up within minutes.
Settling tanks would be the answer incorporated with a settling agent.

Flying Scott You would need a combination of both settleing ponds and filters. The filters i suggested will do alot of good work they are designed to remove micro- material not stones etc. Clay is the enermy here no clay we wouldn't have issues haha |

What types of things are there to aid settling? I know aluminium sulphate works wonders but almost impossible to buy in small quantities. Settling tanks/ponds work a treat if you have the room and money. I may go down that line but in a small way. I am also thinking a longer sluice may help. Have a long run of passive matting of some sort on the tail end with very slow shallow water flow over it. Not sure if this would be any advantage or not. It would collect most of the heavies and then they could be re run later with clean water. Opinions?

How muddy would the water have to be, before the fine gold would not settle in to a riffle or carpet, some where along the sluice ?
Would you say a thick soup !
Having some water to add to the mix may help, there must be a point to where it needs to go through a dry blower, or some system that is water less.
Back in the forum some where was a discussion with Flying Scott on the alternative to using Mercury, was it borax or similar. Would that help ?

Flying Scott I haven't seen an agent, that drop the material out of the water. Scrap my idea of a filter whats the chemical called? It'd work ace in clean up sluice or miller table help settle that last little bit. A wise man once said i am my worse enermy' im always right until i can see the clear picture haha Cheers mate |

Settling agents are quite expensive and none retrievable.

Just a small cyclone unit but can't figure out what he is using it for. |

Check out some of his other clips.
He is highbanking dry areas and recirculating his water. The cyclone helps his water last longer by separating the majority of the debris.

If you know a water or sewage treatment plant operator in your area, I'm sure he would lend you some Aluminium sulphate (alum). Its good stuff to use but for the best results it needs a small amount of contact time and mixing with the incoming water.
Cheers from a retired operator

The old blokes did not have anything like that. They used sluices with corduroy matting. You can buy such matting at Clark Rubber etc. You will just have to reverse the riffling's and make your sluice boxes to suit. The sluice should be about 5 metres long and a half metre wide with a steel letter box crash box.It should be fed slowly. The water will do the work. Let it run and finally let it clear. When you have a build up of black sand at the end stop and wash your mats. Run it at about 1 inch to the foot no more. The crash box serves to break your material up. It should only have about a 12mmm slot. It will work. Forget highbanking. There aint no virgins in heaven, there aint no virgin patches of gold, and there aint no beer in heaven so drink it now. donny
