Described herein is a method for filtration of a solid-liquid composition. The method may include passing the solid-liquid composition through a filter to form a filter cake on the filter and sonicating the filter cake. A filtration system is also provided for filtering a solid-liquid composition. The filtration system includes a filtration device and a sonication device.

A filtration recovery method for filtering and recovering a liquid containing a filtering object that includes: sinking a filtration recovery device including a filtration filter having a plurality of through-holes, an inlet for introducing the liquid, an outlet for discharging the liquid, and a holder having a flow path communicating the inlet and the outlet, and the filtration filter is arranged in the flow path, into the liquid containing the filtering object contained in a liquid storage container with one end side of the holder provided with the outlet so as to capture the filtering object with the filtration filter; introducing the liquid from the outlet of the holder of the filtration recovery device; closing the outlet of the holder of the filtration recovery device; and recovering the filtering object together with the liquid held in the holder of the filtration recovery device.

This disclosure pertains to a process and circuit for producing enhanced manganese-zinc filter cake compositions, and more specifically to a wash process and circuit that produces manganese concentrations of 36-45 wt. % and zinc concentrations of 15-17 wt. % while lowering chloride content to below 3 wt. %. The process and circuit involve sequential washing, drying, repulping, and dewatering of polymetallic filter cakes derived from saline feedstocks, facilitating effective downstream recovery of refined manganese and zinc products.
