Abstract: A system and method for tailings disposal is disclosed. A coarse tailings feed stream and a coarse tailings crusher for crushing the coarse tailings feed stream is provided. A crushed coarse tailings stream may be produced by the coarse tailings crusher, and a disposal stream comprising the crushed coarse tailings stream may be discarded as geotechnically stable waste product. The system and method may further provide a fine tailings stream and a thickener configured to thicken/dewater the fine tailings stream and produce a thickener underflow fine tailings stream. The system and method may provide a mixer configured to mix the thickener underflow fine tailings stream and the crushed coarse tailings stream to form a combined tailings disposal stream. Dewatering apparatus may also be provided.

Abstract translation: 公开了一种尾矿处理系统和方法。 提供粗尾矿进料流和用于粉碎粗尾矿进料流的粗尾矿破碎机。 可以通过粗尾矿破碎机生产破碎的粗尾矿物流，并且包含破碎的粗尾矿物流的废物流可以作为岩土工程稳定的废产物被丢弃。 该系统和方法可以进一步提供精细尾矿物流和增稠剂，其构造成使细尾矿物流增稠/脱水，并产生增稠剂下溢的细尾矿物流。 该系统和方法可以提供混合器，该混合器配置成混合增稠剂底流细尾矿料流和粉碎的粗尾矿料流以形成组合的尾矿处理料流。 也可以设置脱水装置。
