TenOunce Tone said:Have you had a chance to use your screens and blue bowl yrt Headsup. I found an old tea infuser in the kitchen today. It has s real fine stainless mesh. I put some black sand and in and gave it s shake.. low and behold some really small gold was in the ultra fines... had a look with yhe 10x loupe and there is a fair bit of really fine gold in there.. will have a bit more of a play in the daylight and see uf i can get a pic through yhe loupe..
Judt goes to shiw how much hold we throw out!!
I was looking at this spiral gravity trap design today. It is a comervial scale device. 50+ ton an hour but it catches down to 30 micron. I will put a link to it soon.
never seen commercial scale in the spiral bowl machine . i did see some fibreglass spiral things once that looked like a waterslide at the funpark except they were about 3 feet in diameter and 8 feet high , there was about 40 of them used in a mine but i dont know what metal / mineral they were processing
interested to see the one you found
my fine mesh sieves are still on their way from albakirkee . USA
