    摘要: The present invention relates to a one-part polymer grout composition tintable to any desired color upon request, as well as to a method of tinting the grout composition. Advantageously, the present one-part polymer grout compositions may be tinted using any of the multiplicity of commercially available universal colorants, according to fandecks of color based upon the same, or by visual or computerized color matching. Similarly, since conventional universal colorants may be employed, the equipment utilized to tint and agitate paint in order to provide any desired color may be utilized to tint the present grout compositions. A kit is also provided, comprising the tintable grout composition and instructions for tinting the grout composition according to the method.

    摘要: A process for treating a tailings stream comprises (a) contacting (1) a gelling agent and (2) an activator with said tailings stream to produce a gel; (b)entrapping solids including sand and clay, and other solid particles with the gel; and (c) allowing the gel to strengthen and solidify to produce a trafficable deposit; wherein the tailings stream comprises water and solids, which solids comprise sand, clay and other solids particles, and wherein 5% by volume to 100% by volume of the solids have a particle size less than 0.05 mm, based on the total volume of the solids. The process may further comprises spreading the gel produced in step (a) or the trafficable deposit produced in step (c) over a surface. The present invention is particularly useful to treat tailings streams produced in processes to extract bitumen from oil sands ores.
