    My advice is - the majority of readers of this thread will be lucky to accumulate a 5-gal bucket of bs in two or three seasons, therefore, the cost of assays
    and processing do not seem economical. I once had assay done on dredge cons bs and sure enough high gold content. But after trying to lug a half 5 gal.
    bucket up 500 ft to truck - just dumped the other bucket - no regrets. At least wait til you have two or three full buckets before taking that step (or
    PM prices double)

    I can get more than 5 gallons a week in my dredge. Closer to two gallons a day. As for the economics of refining it, I don't know if it would be worth it. Never had them assayed.

    .......you may be surprised?

    Fullpan,you are so right.....most five gallon buckets handles can not hold much over a half bucket

    I had a guy come by the house years ago wanting to buy straight Bs.I didnt know what to even charge so i said $1 a lb....he said fine and that he wanted at LEAST a five gallon bucket,and had $50......I laughed when I told him $50 was not going to get him a 5 gallon bucket!!He says...well whats one full weigh?I said I dunno try to pick one up........he strolled over all cocky and about pulled his arm outta socket when he went to just one hand lift it up!!!

    Well, I might send some off to be assayed just for grins. The problem is transportation. Let's say my BS assays well, then how do I transport hundreds, or thousands of pounds to a refinery willing to buy it? Transport cost and time could easily depreciate the majority of any values.

    Jason - I'm talking about the leftover bs after cycling through at least 2 rounds of gold extraction.

    Kuger - had many buckets rendered worthless (except for using as a stool) when as a noob, I tried to carry too much dirt in
    them and ripping the standard handles off. Bs buckets full weigh about 400lbs, haha!

    It is true if you are a recreational panner and get only a pound or two of blacksand a year it is just not worth bothering with. However if you get even a 5 gallon bucket of it it is. As far as the trucking to a refinery eating any potential profits from refining the blacksands lets look at my numbers because that is exactly what I will be doing. Based on the various assays I have had done the average grade of my blacksands is 1644 grams per ton gold plus silver values of 103 grams per ton.That is 53 ounces gold and 3.3 ounces silver per ton. I will be shipping the sands to a refinery in Trail which is about 230 miles from my claims. I got a quote for trucking a tandem dump and pup trailer load of this material which came in at $1800. per load. Refining cost are $300 per ton.The load will be 30 tons each.Cost then are 30x$300 =$9,000. plus the trucking $1800 dfor total cost of $10800 per load. Now lets look at gross proceeds. Refinery tells me to expect a minimum 85% recovery of assayed values [they never get 100%] so the numbers are this. 53 x $1600 =$84,800 per ton 3.3 x $30. = $99 per ton .
    So gold and silver gross per ton value $84,899.00 x 30 ton per load = $2,546,970.00 X 85% =$2,164,924.50 minus cost of shipping and refining of $10,800 =$2,154,124.50 . gross profit per truck load of blacksands. That is worth fussing over. Based on recovery of blacksands at my mine I will have a load a month to send to refinery. This revenue is almost equivelant to the proceeds from the coarse gold mined on my claims. Below is a picture of the gold I recovered from just twenty pounds of my concentrates using mercury. It is only about 25% of contained assay values but it proves that invisible micron gold can add up to very visible profits.Click image for larger version.

    describe their recovery process?

    Well I found this some time ago when trying to research potential BS values. Without paying the assay fee of course. Lets see if this works... OK seems to be working for now.

    Taken from: (source)

    Bulletin - Google Books






    It goes on with a few more pages like this..
    Then there are a few pages like this..


    And continues on until page 164..
    If you use the link at the top of this post it takes you to Google books where the text is more legible.
    The first page looks like this and the material relevant to this thread begins on page 150 as shown above.
    Funny thing is I posted this link in it's own thread a couple weeks ago and hardly anyone noticed as there was little discussion.
    Anyway big thanks to all who have contributed to this black sand thread, especially the pros thanks for keeping the dream alive!

    What else could be done with black sand? First extract every trace of gold out of it, box it up with a funnel and send it to current administration with a note telling them where to pound it!
    What ever you do with it just get all the gold out of it......
