Problems solved by technology
According to one embodiment, a copper recovery apparatus includes a precipitation tank configured to make a drainage containing copper ions be alkalinity and precipitate copper hydroxide grains in water, a filter aid supplier for supplying an aid composed of magnetic particles or condensed matters and having an average diameter of 0.5 [mu]m to 20 [mu]m, a mixing tank configured to mix the filter aid with a water to produce a suspension, a solid-liquid separator(3) provided with a filter (33) of which the interior is divided into an upper space and a lower space, a suspension supplying line(L7,L2) configured to supply the suspension to the upper space of the separator from the precipitation tank and form a pre-coating layer composed of the aid on the filter, a processed water supplying lines (L2) making the processed water containing hydrogen copper oxide particles pass through the pre-coating layer and the filter via the separation tank and the solid-liquid separator to thereby capture the hydrogen copper oxide particles on the pre-coating layer and supply filtering liquid to the lower space; a peeling water supplying lines (L31,L11) for supplying a peeling water used for peeling the pre-coating layer from the filter to the upper space of the solid-liquid separator; a separation tank (4) configured to receive the detached matter of the pre-coating layer discharged together with the detaching water from the separator to magnetically separate copper hydroxide grains and filter aid, a copper recovery line (L8) configure to discharge and recover the detaching water containing the hydrogen copper oxide particles from the separation tank, and an aid returning line (L5) configured to return the separated filter aid to the filter aid supplier from the separation tank.
