Powdered zinc substitution replacement host machine used in the job, when the replacement of zinc powder was added to the system, the replacement reaction begins simultaneously during delivery, but in the displacement machine is more complete reaction. In addition to completing the displacement reaction, the replacement machine also separates the solid and liquid to obtain a filter cake and a lean liquid. The replacement machine mainly includes a plate filter press and a displacement filter.
The plate and frame filter press is intermittently operated, and the suspension flows under pressure to the side filter group, mainly consisting of a set of filter frames, filter plates and electric compression to form a separate filter. room. After the filter press is pressed, a layer of diatomaceous earth filter layer is placed on the filter cloth, and a certain amount of zinc powder is placed outside the filter cloth, and finally the noble liquid with the zinc powder is added. The displacement reaction is completed after the suspension has passed through the filter layer. The gold mud cake generally contains 3 to 4% water.
The plate and frame type replacement machine is a relatively new type of equipment. It has a cone-bottomed agitation tank with a plate-and-frame filter and a jacket bag. There is a propeller stirrer in the tank. The noble liquid is pumped into the tank by the pump, and the pump is used to suck out the liquid from the annular gathering space of the outer frame of the connecting plate frame. The displacement reaction is carried out while stirring in the tank, and the liquid is passed through the displacement layer to complete the final displacement due to pump suction. The lean liquid is pumped away through the collecting pipe, and the gold mud is continuously sucked onto the filter layer, and the gold mud is discharged from the bottom discharge port, and the gold mud product is obtained by filtration.
