摘要： A method of treating a clay to remove therefrom titanium mineral impurities comprising the steps of mixing an aqueous slurry of said clay having a high solids content with an activator and a collector for the titanium mineral impurities; conditioning the aqueous clay slurry at said high solids content for a time sufficient to dissipate therein at least 25 horsepower hours of energy per ton of solids; adding to the conditioned aqueous clay slurry a polyacrylate salt deflocculant; subjecting the conditioned aqueous clay slurry undiluted containing the polyacrylate salt deflocculant to a froth flotation process and removing the titanium impurities with the froth; and recovering clay having a reduced titanium minerals impurities content.

摘要： A high intensity conditioning mill for conditioning aqueous pulp containing particles of clay and mineral impurities preparatory to subjecting the pulp to froth flotation comprising a conditioning vessel for containing the body of aqueous pulp, a plurality of generally horizontal baffles mounted within said vessel and dividing the interior thereof into a plurality of chambers, each baffle being formed with a central, circular hole, inlet means for feeding aqueous pulp to the lowermost chamber, outlet means for removing conditioned aqueous pulp from the space above the uppermost baffle, a rotatable, generally vertical drive shaft centrally positioned to rotate in said vessel and extending generally concentrically through each hole in each baffle and a plurality of impellers mounted on said shaft and generally positioned within a hole of the horizontal baffle, the impellers being of a size relative to said holes sufficient to provide passageways for the aqueous pulp from each chamber to each adjacent chamber whereby the aqueous pulp is caused to flow from the lowermost chamber to the space above the uppermost baffle while being subjected to the action of the impellers.
摘要翻译：一种用于调节包含粘土和矿物杂质颗粒的含水纸浆的高强度调理磨机，其准备对纸浆进行泡沫浮选，所述浮浆包括用于容纳纸浆体的调节容器，安装在所述容器内的多个大致水平的挡板，每个挡板形成有中心的圆形孔，用于将水浆送入最下室的入口装置，用于从最上面的隔板上方的空间去除调节的含水纸浆的出口装置，可旋转的大致垂直的驱动轴中心地定位成在所述容器中旋转并且大致同心地延伸穿过每个挡板中的每个孔，以及安装在所述轴上并且大体上定位在所述水平挡板的孔内的多个叶轮，所述叶轮的尺寸相对于所述孔足以为每个室的水浆提供通道每个相邻的室，由此使水浆从最低的室流到最上面的挡板上方，同时受到叶轮的作用。
