摘要： @ An improved method and apparatus for froth flotation separation of the components of a slurry, having particular utility for the beneficiation of coal by the flotation separation of coal particles from impurities associated therewith, such as ash and sulfur. In this arrangement, a forward product stream is formed in which a mixture of the particulate matter slurry and the chemical reagents is sprayed through a nozzle at a first relatively low pressure onto the surface of water in a forward stream flotation tank to create a floating froth phase containing therein a first quantity of the particulate matter. The remainder of the particulate matter slurry separates from the froth phase by sinking in the water, and the froth phase is separated as a first product. The remainder of the particulate matter slurry is then directed to a scavenger product stream in which the separated slurry is sprayed through a second nozzle at a second higher pressure onto the surface of water in a second scavenger stream flotation tank to create a floating froth phase containing therein a second quantity of the particulate matter. The second froth phase is then separated as a second product. The amounts of the products recovered in the first and second product streams are substantially independently adjustable by controlling the first and second spraying pressures.
摘要翻译：一种用于浮选分离浆料组分的改进方法和装置，其特别用于通过煤颗粒与其相关的杂质（例如灰分和硫）的浮选分离来选矿。在这种布置中，形成正向产物流，其中颗粒物质浆料和化学试剂的混合物以第一相对较低的压力通过喷嘴喷射到前向流浮选罐中的水表面上以产生浮动泡沫其中含有第一量的颗粒物质。剩余的颗粒物质浆料通过沉入水中与泡沫相分离，并且泡沫相作为第一产物分离。然后将剩余的颗粒物质浆液引导至清除剂产物流，其中分离的浆料在第二较高压力下通过第二喷嘴喷射到第二清除剂流浮选罐中的水表面上，以形成含有其中第二量的颗粒物质。然后将第二泡沫相分离为第二产物。通过控制第一和第二喷射压力，在第一和第二产物流中回收的产物的量基本上可独立调节。
