    does that mean theres a possibility the gold is still in the sand when you sell it or do you you clean gold out first

    I am sure they have a bottom line as far as size of concentrate shipping but I really am not sure what that is. I will be talking with them in the coming week and will find out for you. All I know is they will process a tandem load. They use a cyanide leach on the gold concentrate but because my concentrates are very high in sulphides they roast them first to break down the sulphides and release the micro gold they contain. After the cyanide leach they recover the gold with a carbon in pulp process as described below.............

    Loading gold into carbon



    Leached pulp and carbon are transferred in a counter current flow arrangement between a series of tanks, usually numbering 4 to 6. In the final tank, fresh or barren carbon is put in contact with low grade or tailings solution. At this tank the fresh carbon has a high activity and can remove trace amounts of gold (to levels below 0.01 mg/L Au in solution).

    As it moves up the train, the carbon loads to higher and higher concentrations of gold, as it comes in contact with higher grade solutions. Typically concentrations as high as 4000 to 8000 grams of gold per tonne of carbon (g/t Au) can be achieved on the final loaded carbon, as it comes in contact with freshly leached ore and pregnant leach solution (PLS). This can be measured by comparing the amount of gold extracted from the carbon to the amount of carbon used.

    [edit] Removal of gold from carbon

    The final loaded carbon then is removed and washed before undergoing "elution" or desorption of gold cyanide at high temperature and pH. Ethanol can also be used to desorb gold from activated carbon, but safety concerns have slowed its acceptance in the gold extraction industry.


    I am still actively looking at other refining processes that I may be able to set up in my shop which is only 30 minutes from my mine. I am considering putting in a small plant using the new bio leachants but I wont make that decision until the end of the coming season. It may just be more bother then its worth.

    I wanted to post this extract from an old minister of mines report from Canada.It speaks to the possible values of Black Sands.I have had to edit the names of the creeks and rivers out because I am in the process of waiting for my own assays from samples I took there to come back. If they are any where close to this old reports statements I will be claiming what is surprisingly open to claim ground.

    Seems to me that casual miners (most of us on here) should encourage our local prospecting club to gather everyone's black sands as a fundraiser for the club...pay your annual dues with sand! The club could likely accumulate enough to be worth getting it assayed and processed. What do you all think of this? Anyone done it?

    Excellent idea Kevin - If all clubs contributed to the pot, then make one shipment per year, I'm sure they could finance their X-mas parties anyway! Some
    clubs do a version of this now with aluminum cans.

    I think I might have to mention this idea to my club. We're having several beach outings this year and the area has literally tons of black sand. Of course I think there is a law out here that says you can't remove more than 10 gallons of material, but if everyone had 10 gallons of black sand, that would be well over a ton! Might be interesting to see what that would be worth.

    Thanks guys, I am going to promote this idea here in Denver too. If each of you takes 10 gallons, you will be amazed since 5 gall of wet black sand is over 200 pounds!!

    That stuff is dense ya know!

    Tell me about it! First time I tried to go beach prospecting, I lugged half a bucket of BS half a mile from the beach to my car. NEVER doing that again!! I thought my arms were going to fall off! It wasn't until after I got back that the old timers tell me to take a wagon with me... Lesson learned!

    Is that 1/2" EMT electrical tubing? I was an electrician for over 20 years so I recognize the set screw coupling in front of the wheel, I just don't see how EMT could hold up to pulling 2 or 3 hundred pounds around at a time. I agree with fullpan it is very cool!

    Good eye Meagen's Dad

    I'm surprised at how well it has held up so far but will most likely replace it with GRC when the EMT fails.
    The only problem so far has been a twisting of the long handle when extreme weight is being hauled.

    I'm sure it's just a matter of time until the handle fails.
