この発明はメッキスラッジから有用金属を高品位で回収

、収率。As is well known, when electroplating copper strips continues for a long time, sludge containing the plating solution composition and other substances accumulates at the bottom of the plating tank. If a large amount of this sludge accumulates, it will float in the plating solution.
This sludge must be periodically discharged because it adversely affects the quality of the plating. However, this discharged sludge contains a considerable amount of plated metal, and collecting and reusing this plated metal is important from the perspective of resource conservation, and there has been a conventional method for recovering useful metals from plated sludge. Various techniques have been proposed. Carbon reduction method and hydrogen reduction method are known as effective techniques for recovering useful metals from plating sludge.These methods reduce metal oxides contained in sludge, but the yield is low. .
回収物の純度の点から水素還元法が好ましい。The hydrogen reduction method is preferred in terms of the purity of the recovered material.

、回収金属中にこれが混入し、回収金属の品位を低下さ

った。However, in the well-known 7-Erostane type electrolytic Sn plating, organic substances such as phenol sulfonic acid (PSA) and brighteners (EN, ENSA) are included as essential components. Treatment using the reduction method has the disadvantage that organic substances are decomposed and partially carbonized in the hydrogen reduction process, and this is mixed into the recovered metal, lowering the quality of the recovered metal and deteriorating the properties of the recovered metal.

９００℃が適当で、所定時間還元処理する。Plating sludge is appropriately discharged from plating tanks, drag-out tanks, water washing tanks, etc. This plating sludge is dried in a desired manner. After drying, roasting is usually performed in a rotary kiln, but other furnaces may be used. The roasting process is carried out in an oxidizing atmosphere, but at low temperatures it is difficult to thermally decompose and remove organic matter, while at too high a temperature useful metal oxides will sublimate rapidly. 600 to 1000°C (preferably below 850°C) for a suitable period of time. It is possible to obtain powders or granules with properties suitable for hydrogen reduction such as tin oxides and tin oxides.This roasted product is then subjected to hydrogen reduction, but the atmosphere is Although a high hydrogen concentration is preferable, for example, a mixture of 5% or more H2 and the balance N2 may be used.The temperature is 500~
A suitable temperature is 900°C, and the reduction treatment is carried out for a predetermined period of time.

が推奨される。In this hydrogen reduction, as a method for storing the roasted material and recovering useful metals, the tilting method, that is, a method in which the roasted material is placed uniformly on an inclined plate and the reduced metal is allowed to flow downward and be recovered, can be adopted. In addition to this method, the mesh container storage method is recommended as a method that has a large contact area with the gas and has good workability.

回収される。That is, after the roasted product H is stored in the mesh container 3, the mesh container 3 is placed in the hydrogen reduction furnace 2 and heated and reduced with hydrogen. The metal is reduced by the hydrogen passing through the roasted material screen 4, and the molten reduced metal drips from the porous plate 5 and is collected in the metal collection tray 6.
