Abrégé
The present invention relates to stable ionic xanthate compositions in aqueous solution for prolonged periods of time that are useful as collector reagents in the froth flotation process. The stable ionic xanthates of the present invention are dissolved in aqueous solution at their maximum water solubility (28-30%), being highly stable and safe ionic products, preventing the instability and flammability of the solid products which allows safe handling, both for operators in mining work and for the environment.

Abrégé
The invention relates to a method for forming blasthole stemming for mining, which comprises charging a blasthole with a two-component mixture of resin and catalyst, wherein the two-component mixture produces a stiff foam in situ, and once hardened, the two-component mixture is then detonated. The invention also relates to a system for forming blasthole stemming for mining in order to carry out the method; the mixture used as blasthole stemming for mining that comprises the two-component mixture of resin and catalyst, wherein the resins are based on formaldehyde; and to a method for charging and detonating a mining blasthole by using the two-component mixture.
