Tungsten rings gold ring zoned wall coating strength test results show that tungsten gold ring hardness, not easy to scratch, do not wear, good gloss, strong metal.

First pump 60 mesh sieve shaker set under the sand formulated taking the weight ratio of solid and liquid slurry of 20% and pumped to the top of our nylon spiral chute processing so that the slurry flowing down naturally video seen, on the inside of the mineral with a large proportion of particles containing gold, iron ore, tungsten and tin of black sand, and other minerals.Outside next to a light particle, the outermost is muddy water, can spiral off the mud, if applied in the coal mine, but also the separation of pyrite, lower ash content of coal gangue, coal washing works well.
