ABSTRACT:
A chemical reagent is mixed with the mixture to form a resultant reaction mixture under substantially nonoxidizing or oxygen-free conditions. A continuous movement of the resultant reaction mixture is established through a flotation zone while maintaining substantially quiescent flow conditions during the continuous movement thereof. A first outlet is used to discharge a free or unimpeded flow of material collected at the upper surface of the liquid carrier medium within the flotation zone. A second outlet is used to discharge an impeded flow maintained at a lower flow rate than the free flow from said first discharging outlet. The chemical reagent is composed of a liquid hydrocarbon, a reducing material and an activator material. A trough shaped vessel has a discharge end with an upper outlet means and a lower outlet means. The vessel has a structural configuration effective to provide the continuous, substantially quiescent movement of the mixture through the vessel. Mineral value fines subject to having an oxygen-controlled surface condition constitute the selected particulate material being extracted from the mixture of liquids and solids. These selected materials include bituminous coal fines, anthracite coal fines, molybdenum sulfide values, sulfur and graphite.
