Provided is a method for processing electronic and electrical device component scrap, which can improve an efficiency of sorting of raw materials fed to the smelting step from electronic and electrical device component scrap, and reduce losses of valuable metals. A method for processing electronic and electrical device component scrap which includes sorting electronic and electrical device component scrap by wind powder sorting to remove plate-shaped materials containing valuable metals included in the electronic and electrical device component scrap, and then sorting the resulting sorted objects by magnetic sorting.

Method for processing electronic and electric device component scraps

Provided is a method for processing electronic and electrical device component scrap, which can improve an efficiency of sorting of raw materials fed to the smelting step from electronic and electrical device component scrap, and reduce losses of valuable metals. A method for processing electronic and electrical device component scrap which includes removing powdery objects contained in electronic and electrical device component scrap prior to a step of separating non-metal objects or metal objects from the electronic and electrical device component scrap containing the metal objects and the non-metal objects, using a metal sorter including: a metal sensor, a color camera, an air valve, and a conveyor.

Method for processing electronic/electrical device component scraps

Provided is a method for processing electronic and electrical device component scraps, which can selectively recover a substrate scrap including a substance intended to be recovered. A method for processing electronic and electrical device component scraps, including separating a substrate with lead wires contained in the electronic and electrical device component scraps before sorting the electronic and electrical device component scraps by magnetic sorting.

An object of the present invention is to provide a sputtering target that can suppress a generation amount of fine nodules which lead to an increase in substrate particles during sputtering, and a method for producing the same. A ceramic sputtering target, the sputtering target having a surface roughness Ra on a sputtering surface of 0.5 &#x3bc;m or less and an Svk value measured with a laser microscope on the sputtering surface of 1.1 &#x3bc;m or less.

Sputtering target and producing method thereof

Provided is a method for removing wire-form objects, a device for removing wire-form objects, and a method for processing electronic/electrical apparatus component waste, which can efficiently sort wire-form objects from sorting target objects having various shapes. The method for removing wire-form objects includes: arranging a filter in a vibrating sieve machine, the filter including a plurality of rods extending at distances in a feed direction of a raw material; and placing a raw material containing at least wire-form objects and plate-form objects onto the filter, and vibrating the filter to sieve out the wire-form objects under a sieve.

Method for removing wire-form objects, device for removing wire-form objects, and method for processing electronic/electrical apparatus component scrap

In the electrolytic refining of lead in a sulfamate bath, the production of a white residue is suppressed, and a decrease in the lead concentration in the electrolytic solution is suppressed. A method for electrolytically refining lead in a sulfamate bath, comprising performing electrolytic refining at a decomposition rate of sulfamic acid controlled at 0.06%/day or less.
