A system and method for reducing pollutants in garbage leachate is disclosed. The system comprises multiple modules such as a screening module, a pH adjustment and mixing module, a separator module and a disinfection module operationally connected to each other. The screening module is configured to filter the leachate and the pH adjustment and mixing module is configured to adjust the pH of the filtered leachate to a predefined value. The leachate is mixed with a chemical or metal oxide composition, and the pollutants in the leachate are adsorbed by the chemical composition to provide a purified leachate. The separator module is configured to separate the adsorbed pollutant from the purified leachate. The disinfection module is configured to filter and disinfect the purified leachate to produce purified water. The method implemented using this system for reducing pollutants in a leachate is efficient and economical.

A device for separating weakly magnetic first particles, for example hematite particles, from mixture (912) comprising the first particles (913) and less magnetic second particles (914) is presented. The device comprises first magnetizing equipment (901) for producing magnetic field and for moving the mixture so that mutually opposite polarity portions (N, S) of the magnetic field sweep the mixture in a sweeping direction and thereby deflect the direction of movement of the first particles towards the sweeping direction and away from the direction of movement of the second particles. The device comprises also a supply equipment (932) for supplying the mixture to the carrier equipment with the aid of gravitation and a second magnetizing equipment (931) connected to a feed box (920) for producing second magnetic field for deflecting a direction of movement of the first particles differently than a direction of movement of the second particles when the mixture is moved by the gravitation towards the carrier equipment so as to generate, to the mixture arriving at the carrier equipment, a concentration gradient of the first particles. The pre-concentration of the first particles simplifies their separation form the mixture.

Proposed is a process for separating a leach residue from which a hematite-containing material that can be used as a raw material for ironmaking can be obtained, and provided is a production process of hematite for ironmaking from the leach residue. The process for producing hematite for ironmaking using, as a raw material, the leach residue in a slurry state obtained from a hydrometallurgical plant for nickel oxide ore utilizing a high pressure acid leach process comprises in sequence: a first step of separating the leach residue in a slurry state into an overflow and an underflow using a wet cyclone; a second step of separating the overflow into a strong magnetic component and a weak magnetic component using a strong-magnetic-field magnetic separator utilizing magnetic force; and a third step of sintering the separated strong magnetic component at a temperature of 1150 to 1350 C. to form a sintered body.
