Tailing Dry Stacking,the helper of water saving in

This system realizes the tailing water recycle use, and reduces consumption of raw water. Experiments show that: in ore dressing plant of an annual tailings emission of 1000000 tons, Xinhai tailings dry stacking system recycles 2000000 tons water per year. By 1.5 yuan / T, the annual savings of water charges 3000000 yuan / year.
