摘要： A method of processing waste lead-acid batteries includes a crushing step, a sorting step, a plastic fragment treating step, and a plastic bit recycling step. Through the four steps, waste lead-acid batteries are turned into lead fragments, high-density plastic fragments, and plastic bits, which are recyclable as reusable materials, respectively. Moreover, waste liquid and waste gas in the waste lead-acid batteries are sent to a waste liquid treating equipment and a waste gas treating equipment, respectively, for further appropriate treatment. Therefore, the method may appropriately recycle useful materials of the waste lead-acid batteries and prevent the waste liquid and the waste gas from polluting the environment.

摘要： A separation device includes a first shredding unit, a first separation unit, a second shredding unit, and a second separation unit. The first shredding unit shreds a processing target containing a first material and a second material. The first separation unit rotates a first tubular portion in a state in which the processing target shredded by the first shredding unit is accommodated therein, thereby separating the second material passing through first holes from the processing target. The second shredding unit shreds the processing target from which the second material passing through the first holes is separated by the first separation unit. The second separation unit rotates a second tubular portion in a state in which the processing target shredded by the second shredding unit is accommodated therein, thereby separating the second material passing through second holes from the processing target.

摘要： The present invention relates to a method for treating a plastic and/or paper waste material having steps including collecting a plastic and/or paper waste material, preferably paper, and highly preferably a release coated cellulose or polymeric sheet material. The material already includes a selected new-use additive preferably selected from flame retardant, hydrophobic material, pesticide, herbicides, minerals, nutrients, and/or mixtures thereof. The method includes the step of preparing the collected material by mixing, separating foreign bodies like metals, etc., and feeding it to a grinding station. The method also includes the step of, in one or several grinding stations, shredding and grinding the materials into small pieces.

摘要： A method of pulverizing solid material for the purpose of extracting metals which may otherwise not be recoverable and/or cost prohibitive using conventional means and processes, said method comprising the steps of: using a gas to create a fluidized flow of previously crushed solid material; transporting the fluidized flow of solid material to an apparatus which induces a high velocity flow stream in a constricted low-pressure stream; causing a rapid acceleration on a rotational angle of the crushed solid material resulting in increased interparticle collisions and collection of solid particles; and ejecting the material at a high rate of speed from the apparatus to a focal point where the material is pulverized.

摘要： This invention relates to a process for recovering value metals from sulphide ore, including steps of crushing ore in a primary crusher (14) to a size of about 40 cm and less, passing the crushed ore through one or more of the following pre-beneficiation processes such as bulk sorting (16) and screening (20) followed by coarse floatation (46/50), or gravity separation or magnetic separation. A waste stream (54) from the pre-beneficiation process/es with a particle size greater than 100 μm is stacked in a heap (26) and subjected to a heap leach. This integrated process utilises the pre-beneficiation techniques best suited to the characteristics of a particular orebody; and during the pre-beneficiation simultaneously creating a low grade stream that yields significantly higher recoveries than achievable by normal heap leaching of low grade run of mine ore.

摘要： A method of preparing an aluminum metaphosphate (ALMP) particulate product includes charging a milling chamber of a ball mill with grinding media and loading an ALMP feedstock into the milling chamber. The ALMP feedstock is milled with the grinding media into ALMP particles at a particle reduction index in a range from 0.25 to 0.5. At a plurality of time steps during a period in which the milling is carried out, a fine fraction of the ALMP particles is removed from the milling chamber while a coarse fraction of the ALMP particles remains in the milling chamber for additional milling. An ALMP particulate product with a particle size distribution having a median particle size in a range from 100 μm to 700 μm is prepared from the ALMP particles removed from the milling chamber.
