Proposed is a separation method of black powder of an automotive waste secondary battery. More particularly, a method of separating a black powder (Ni, Co, Mn, Li C)+metal (Cu, Al) compound extracted from an automotive waste secondary battery through magnetic separation and particle separation is proposed. The separation method of black powder of an automotive waste secondary battery according to an embodiment of the present disclosure includes: (a) extracting black powder+metal compound from a waste secondary battery; (b) separating the black powder+metal compound into black powder and a metal compound through particle separation; and (c) separating Co and Ni, and non-extracted Mn, Li, and C by extracting Co and Ni from the black powder through gravity separation.

A method and apparatus to reclaim metals from scrap material such as automobile shredder residue (ASR) that, after separating out light density components, separates out friable material such as rock and glass by crushing and screening operations to generate a high metal content product.

The present invention describes a process for removing uranium from a copper concentrate by magnetic separation (low and high field) to reduce the uranium content to commercially acceptable levels.

A method and apparatus to reclaim metals from scrap material such as automobile shredder residue (ASR) that, after separating out light density components, separates out friable material such as rock and glass by crushing and screening operations to generate a high metal content product.

A method for recovering a valuable substance is provided. The method includes a thermal treatment step of thermally treating a target containing a valuable substance using a continuous furnace configured to thermally treat the target while moving a target storing unit, in which the target is stored, such that the target storing unit is not contacted by a flame that is for thermal treatment, and a valuable substance recovering step of recovering the valuable substance from a thermally treated product of the target obtained in the thermal treatment step.

A modified selective recirculation circuit has a loading stage, a stripping stage and a filtering stage for use in processing a feed stream or slurry containing mineral particles. The stripping stage forms a first loop with the loading stage, a second loop with the filtering stage. The loading stage has a loading mixer and a loading washing screen. The stripping stage has a stripping mixer and a stripping washing screen. The loading mixer receives the slurry and causes barren media in the circuit to contact with the slurry so that the mineral particles in the slurry are loaded onto the barren media. The media is directed to the stripping stage where the mineral particles are removed from the media. The barren media is recycled to the loading stage. The stripping solution recovered from the filtering stage is returned to the stripping stage and the mineral particles are discharged as concentrate.

Provided is a method for efficiently separating copper from nickel and cobalt from a sulfide containing nickel and cobalt together with copper. The present invention is a method for separating copper from nickel and cobalt, the method comprising pulverizing a sulfide containing copper and nickel and cobalt into a predetermined size and then stirring the resultant product under the condition having an oxidation-reduction potential (a reference electrode: a silver/silver chloride electrode) of less than 100 mV using an acid solution to perform a leaching treatment. In this separation method, a leach liquor in which nickel and cobalt are leached and a leach residue containing copper sulfate are produced as the result of the leaching treatment.

The present invention provides a manufacturing method of crude copper from low-grade copper sludge, one embodiment of the present invention comprises the steps of: (1) calcining a low-grade copper sludge (step 1); (2) producing a mixture by adding at least one selected from a group consisting of binder, flux and combinations thereof to the calcined low-grade copper sludge (step 2); (3) producing a briquette by compression molding the mixture (step 3); (4) melting and reducing by charging the briquette into a submerged arc furnace with adding flux (step 4); and (5) separating crude copper and slag produced by melting and reducing (step 5).
