Cryogenic liquid samplers are provided to address problems of fractionation of cryogenic liquid during volatilization. The sampler includes an inner volume and a useful internal length, a cryogenic liquid inlet conduit in fluid connection with an inlet valve, a weir tube in fluid connection with the inlet valve, wherein the weir tube comprises at least one weir hole, wherein the weir tube extends a predetermined distance into the inner volume, a cryogenic liquid outlet conduit in fluid connection with inner volume and in fluid connection with an outlet valve, and a purge tube in fluid connection with the outlet valve.
Methods for sampling cryogenic liquids to address problems of fractionation of cryogenic liquid during volatization. One embodiment of the method includes: closing both the inlet valve and the outlet valve, connecting a cryogenic liquid source to the cryogenic liquid inlet conduit, and introducing cryogenic liquid into the cryogenic liquid inlet conduit; opening both the inlet valve and outlet valve, thereby introducing cryogenic liquid into the sampler vessel inner volume, the cryogenic liquid has a free surface; closing both the inlet valve and the outlet valve after cryogenic liquid flows from the purge tube; disconnecting the cryogenic liquid source from the cryogenic liquid inlet conduit; opening the inlet valve, thereby allowing cryogenic liquid to flow from the cryogenic liquid inlet conduit; and closing the inlet valve after the free surface in the sampler vessel inner volume drops below the top of the first cryogenic liquid level, and the cryogenic liquid flow stops.
A product is chilled or at least partially frozen by descending against a counter-current flow of liquid nitrogen in a vertical freezer containing an immersion bath of liquid nitrogen and the chilled or at least partially frozen product is extracted from the bath. The product may optionally be a liquid, semi-solid, suspension or slurry.

Abrégé
3/ton consumed by the treated ore, the surface of the iron sulfide particles may be partially or even totally oxidized, thus allowing better separation. As a consequence, the iron content is decreased, and the grade of the mineral value such as zinc, copper, and nickel increases. Also, sulfide emissions during heat treatment or further processing of the minerals are decreased due to decrease iron sulfide content.
