how much does an inground pool cost?




limetemple


medium size


Answer
Medium size would be an 18 x 36. Costs of construction can vary enormously. Expect that size pool to start at about 18,000 canadian dollars for a vinyl inground. A concrete (gunite) pool would be about 28 grand to start.
Extra costs can be incurred if the access to the dig is difficult, material has to be trucked father away to dump, if the area the dig is in is in a high water table or is very rocky.. The toys you want with the pool, like water falls or adjacent hot tubs. The pool equipment packages can vary from basic to hi tech advanced remote wall unit controls in the house for heat, automatic pool cleaner controls and even one touch and forget, timed pool fill valves.

Can anyone tell me how Automatic Gold Dredgers work?

I have been trying to figure out how something that separates the gold from the mud/sand work??

and i am getting NO WERE, lol.

Can someone explain it to me?



Answer
No prob, I live in gold country. There are the floating self sustaining dredges. They are fairly small dredges on floats. They are usually anchored. There's a suction hose that acts similarly to an automatic pool cleaning device. It moves around the bottom and deposits the silt i.e. mud/sand into a shaker box where water is continually run through. Since gold is more dense/heavier than sand/mud it tends to not be washed away. It all has to do with the periodic table of elements and their mass. What it comes down to is a filtering action where the heaviest particles stay and the lighter slag is washed away. There's also a less autonomous system where a diver uses the suction hose and manually vacuums the bottom. Hope it helps.
