4 <br /> r t <br /> r' <br /> 1 <br /> f f. <br /> FIGURE 1. - Water jet. <br /> t <br /> polymers have been tried in the Bureau laboratory. Best conditions and effec- <br /> tive rates of application have been determined for most of the promising mate- <br /> rials. The more effective chemicals of those tested are listed below in order <br /> of effectiveness based upon the cost in cents for the amount of reagent <br /> required to stabilize 1 square yard. An overlapping of costs resulted because <br /> some reagent requirements varied for different tailings. General conclusions <br /> derived from the comparative data are as follows : <br /> k^� <br /> ` 1. Coherex,4 a resinous adhesive, furnished good wind-resistant tailing <br /> --� surface when applied in quantities equivalent to 240 gallons per acre and cost <br /> ing approximately $65 per acre, but good resistance to water jet testing was <br /> • not achieved until reagent quantities costing $650 per acre were applied. <br /> 4Reference to specific company or brand names is made for identification only <br /> and does not imply endorsement by the Bureau of Mines. <br />
