    摘要: Methods of increasing the rate of separating hydrophobic and hydrophilic particles by flotation have been developed. They are based on using appropriate reagents to enhance the hydrophobicity of the particles to be floated, so that they can be more readily collected by the air bubbles used in flotation. The hydrophobicity-enhancing reagents include low HLB surfactants, naturally occurring lipids, modified lipids, and hydrophobic polymers. These methods can greatly increase the rate of flotation for the particles that are usually difficult to float, such as ultrafine particles, coarse particles, middlings, and the particles that do not readily float in the water containing large amounts of ions derived from the particles. In addition, new collectors for the flotation of phosphate minerals are disclosed.

    摘要: A single dose of additive contributes to three consecutive fine coal unit operations, i.e., flotation, dewatering and reconstitution, whereby the fine coal is first combined with water in a predetermined proportion so as to formulate a slurry. The slurry is then mixed with a heavy hydrocarbon-based emulsion in a second predetermined proportion and at a first predetermined mixing speed and for a predetermined period of time. The conditioned slurry is then cleaned by a froth flotation method to form a clean coal froth and then the froth is dewatered by vacuum filtration or a centrifugation process to form reconstituted products that are dried to dust-less clumps prior to combustion.

    摘要: A reagent and a method for using the reagent for treating a solid material disposed in a liquid medium and having an oxygen-controlled surface condition. The reagent includes a liquid hydrocarbon, a reducing material and an activator material. The liquid hydrocarbon has a specific gravity different from the specific gravity of the liquid medium. The reducing material is present in an amount sufficient to establish a reducing environment around the solid material for breaking the oxygen control on the surface of the solid material. The activator material is present in an amount sufficient to establish an electrostatic charge on the solid material after the oxygen-controlled surface condition has been broken. A more specific feature of the invention is directed to the method of flotation of extremely fine bituminous coal having an oxygen-controlled surface condition. The reagent is useful in froth flotation processes and in bath flotation and separation processes.

    摘要: A multi-stage float sorting device includes a first flotator float-sorting ores mixed with water based on a difference in density, and a second flotator provided with a column extending in a top-down direction, one side of which communicates with the first flotator to receive primary concentrates, and float-sorts the primary concentrates based on a difference in density to obtain secondary concentrates. The second flotator includes a washing water jetting section provided at a top of the column to jet washing water, a gas sparger provided at a bottom of the column to jet an inert gas, and an opening and closing section located between the washing water jetting section and the gas sparger to partition an inside of the column into upper and lower regions, and form an opening for rising secondary concentrates in the column according to a pressure state of the lower region.
