    Something for the small operator

    I was at the Elko Nevada Mine Expo last week and talked a little to these guys at LNW Engineering. Not many manufacturers who come to the event cater to smaller operations, but once in a while you'll see one. I thought their concept looked like it would be something in the way of efficient recovery. It would have been better if they'd had it up and working to give any potential prospects how good thier equipment is, as that's what most miners I deal with lead me to believe, when they tell me prove it and I'll consider your claim.

    That is a Knudsen bowl concentrator and they have been around a long time. They probably didn't have it running because all you would see is concentrates.

    Yeah I was telling that guy it looked like a previous design, but couldn't think of what it was called. He knew what what it was, but his is scientifically engineered he said. I did once see this shaker table running cons at a show.

    An ICON 150 is $8900 shipped on Ebay all day long. So unless they have a better price point and it works as well as the iCON, I don't see it doing well.

    I have 4 of these at my mine, they work well but need mercury in them to be really effective. I always run a test pan afterwards and see no color whereas when using a sluice I always see a bit of color. We call them separators or coil bowls. I buy mine for $1200 each USD

    If they need mercury added to them, then they are really not that effective. I do know that the iCON 150 works great as long as the water pressure is kept consistent.

    Sure, without mercury they operate at around 80 percent on old rubber liners and around 90 percent on new liners. Just researched the icon 150, says it does 2 tons per hour and the cost of the unit is $8000 on eBay. The separators I use also do around 2 tons per hour and cost $1200 each.

    Just thought I would put that out there as not every small scale miner can afford $8000.

    If you wanted to run without mercury, you can put a 2 meter expanding sluice after the separator and you could probably achieve 95%.

    Huh, I asked that guy at LNW how much, but he wouldn't tell me and just said, that depends. Anyway I thought it was neat someone would have something for the smaller operations. Maybe you can post a video of this coil bowl in action sometime pczim. It be interesting to see what it can do.

    Mercury isn't for me. I'm crazy enough as it is. Lol.

    To me mercury just presents too many problems just as cyanide does. Sure it can be used effectively and safely but all it takes is one slip up and it's all over. And with the lack of experienced miners here in the States everything has to be dumbed down to the lowest common denominator.

    I saw an old Mercury Retort in an indoor antique mall. The vendor thought was a cast iron Dutch oven. I didn't buy it, because it was hundred bucks. If it had been like twenty to thirty I might have.
