Abstract

A method for treatment of mining waste. The method comprises adding the mining waste and a flowable solidifier to a container. The flowable solidifier comprises one of a flowabie geopolymeric former and a flowable cement former, or a combination thereof. The flowable geopolymeric former possesses the ability to produce a geopolymeric reaction by itself or in combination with the mining waste. The flowable cement former possesses the ability to produce a cement solidifying reaction in which concrete is formed. The method further comprises combining the mining waste with the flowable solidifier into a formable combination, and solidifying the formable combination by allowing the geopolymeric reaction and/or the cement solidifying reaction to form a solidified combination.
