Abstract

See full text

A process for treating a tailings stream comprises (a) contacting a deionized silicate solution with a tailings stream whereby the solids are entrapped within a gel produced from the silicate solution; and (b) allowing the gel to strengthen and solidify. The process may further comprise spreading the gel produced in step (a) over a surface. The present invention is particularly useful to treat tailings streams produced in processes to extract bitumen from oil sands ores.
