 Hi, I'm Charlie Comstock with Model Road at Hobbyist Magazine and I'm here in the Cascade County Narrow Gauge Layout with Dave Klune. Have you ever had any desire to put sound in buildings? Just fix sound effects? Well, I do have sound in one building and that is the Stamp Mill, has a sound in the lights. Oh great. So let's take a look at that. Okay. This is the M&M Mining Company's Black Rock Concentrator. It starts by the ore being brought in by one ton rolling buckets cars and dumped into a bin up here where it's crushed to size and then fed into some stamp, 20 stamps here is called a 20 stamp stamp mill and it uses a cyanide process to process the gold. The gold is crushed in the stamps and it goes through a pan that has mercury on it and it gets the larger pieces of free gold that hears to the mercury. The rest of it washes off the bottom of this plate there and is directed to a pump, a sand pump here that pumps the slurry of crushed ore up to a separator inside this building here and it separates the fines from the sand and the sand is separated out through a cyclone and brought over to some outdoor metal tubs that circulate and there's two of them and then the fines are sent to this wood tub here and it has air blowing through it separates it and is mixed with a weak solution of potassium cyanide and then from there it is pumped to these various vats that over a period of time extract the gold ore the cyanide itself dissolves the gold and silver ore and it starts here goes to the next one goes to the next one and so on and so forth till it gets down to the last one and then it is extracted the uh pregnant liquor they call it the liquid is pumped to a gold tank here and is fed into a uh building here that has boxes of zinc and the ore water and everything pass over the zinc the zinc absorbs the gold and silver whereas the water passes out and is returned to the uh holding tanks within the mill recycled and uh then the gold ore is held in these iron boxes of zinc and then about once a month they are taken out and they are cleaned in a vat of sulfuric acid now this is the same potassium cyanide and sulfuric acid they used to kill people with so you know that the people that worked here probably didn't enjoy a long life so that's the reason for this tall smokestack or vent is to vent off those fumes and uh if this is a properly modeled and long lived mill all the vegetation around here would be dead because of the gas anyway after it's been washed in sulfuric acid excuse me it is again pumped to a building here that has a dryer in it and the dryer dries the ore and it is put in cans and shipped out on the railroad the cans are about 80 pounds and they're loaded in each end of the boxcar over the trucks to about 25 tons and are shipped to a further refining where they acid part the silver and gold the gold and silver are approximately 98 pure and that's again this is the boiler room with the boilers smokestack and this is the the gold room where they process the the ore I mean the gold ore into the buckets and ship it out and that's somewhat very abbreviated the process of the gold ore this took about 10 years of research and about three years of construction do you believe that there's any such thing as a completed model railroad I don't I think there's probably always something to do if nothing more you could take the trees off and re re finish the scenery new techniques new ideas so I think there's lots to do we're not done by a long way so if you had any advice for uh newcomers to the hobby what would that be you don't need a gymnasium like john armstrong said you know for every square foot of bench work it only takes an hour to build for every square foot of scenery it's 10 10 hours to build so you just figure your square footage and add 10 to it and that would give you a kind of an idea of what the building the scenery if you go to an acceptable level so yeah well thank you very much for having us Dave and it's been a real pleasure coming here and looking at this layout you obviously have more than average levels craftsmanship in you well thank you very much for coming by and we'll go run some trains okay great all right
