metal processing facility and slurry tailings

    What are Tailings?, Although tailings are composed of materials such as silica, which is a somewhat sought-after material, it may contain highly toxic metals that can pose an extreme environmental hazard Additionally, most of the processing methods involve the use of cyanide and copper sulfate, which are ,Historic Mills and Mill Tailings as Potential Sources ,, Historic Mills and Mill Tailings as Potential Sources of Contamination in and near the Humboldt River Basin, Northern Nevada , mineral-processing facilities (smelters, mercury retorts, heap- , and most tailings emerged as a wet slurry, tailings tended to be placed in arroyos or stream channels that carryThe final tailings slurry produced by the process ,, In a metal processing facility, the final tailings slurry produced by the process is thicken in a caisson and thickener and pumped out of for disposal The density of the slurry that leaves the thickener must be maintained at a set point of 75% Proximity switches are installed on the outletTailings, The water removed can thus be reused in the processing cycle Once a storage facility is filled and completed, the surface can be covered with topsoil and revegetation commenced , In paste tailings the percent of solids in the tailings slurry is increased through the use of paste thickeners to produce a product where the minimal separation .Article Slurries: A Solid Challenge, Article Slurries: A Solid Challenge , After the nickel is removed from the slurry at the processing facility, the tailings (also a slurry) can be transported to the , the solids in the slurry will continuously scrape against the port of the valve, like a metal ,.
