摘要： The present invention relates to a method and apparatus for removing and recovering copper by treating an acidic waste liquid containing copper ions such as an etching waste liquid resulting from etching a copper printed board in an etching solution of cupric chloride and a waste liquid after renewing a plating bath liquid in producing electrolytic copper foil. In particular, a copper recovering method of recovering copper from a copper-containing acidic waste liquid includes adding a liquid mixture of a copper-containing acidic waste liquid and an oxidizing agent to an alkaline agent solution while a pH of the alkaline agent solution to which the liquid mixture has been added is being controlled so as never to decrease to seven or lower, and by obtaining a solid material whose main component is copper oxide.

摘要： A system and method for recovering a metal value from a metal-bearing ore material are provided. A metal-bearing ore can be mixed with certain substances and to form an agglomerated ore. In an intermediate state, between agglomeration and heap formation, bacteria can be added to the metal-bearing ore material to produce an augmented ore. The augmented ore can then be formed into a heap. Bacteria from the heap may be fortified to assist in bacterial growth.

摘要： A solvent extraction settler arrangement comprising a mixing unit for preparing a dispersion from mutually immiscible solutions and a settler having a feed end and a discharge end. The settler is arranged to separate solution phases from a dispersion fed from the feed end while the dispersion flows towards the discharge end. The arrangement further comprises a feeding device located at the feed end for feeding the dispersion prepared by the mixing unit to the settler. The feeding device comprises an elongated feed launder having a first end for receiving the dispersion from the mixing unit, and a second end. The feed launder extends alongside the feed end of the settler. The feed launder has a form of a conical tube with a cross-section converging towards the second end and an inclined bottom ascending towards the second end. A plurality of feed pipes are arranged along the length of the feed launder at a distance from each other, each feed pipe having a third end opening to the inner space of the feed launder at the bottom to receive the dispersion from the feed launder and a fourth end opening to the settler to conduct the dispersion to the settler.

摘要： Mechanical visbreaking and pyrolysis between counter-rotating coaxial centrifugal impellers in a continuous radial counterflow process minimizes wastewater discharges. In one example, a cataclastic shear retort comminutes, shear thins, and shear heats an axial feed, such as tar sand, oil shale, coal tailings, distillation bottoms, or lignite. Pyrolyzing the feedstock in this shear retort yields a product stream of gases, naphthas, and oils which first mixes with the feedstock and then is axially extracted, while spent solids are simultaneously extruded from the periphery as coked devolatilized residue, such as char sand for upgrading soil to terra preta. Recirculation of shear-heated solids in long residence time within the shear retort brings heat from the spent solids at the periphery to the feedstock without an external heated sand loop. CO2 emissions from combustion to heat water for oil extraction are eliminated.

摘要： A nickel recovery loss reduction method that makes it possible to reduce nickel recovery loss by lowering the concentration of fine floating solid components in overflow liquid in precipitating and separating treatments, and consequently to further reduce a nickel recovery loss, a hydrometallurgical method for nickel oxidized ore to which the nickel recovery loss reduction method is applied, and a sulfurizing treatment system. The present invention is a nickel recovery loss reduction method in a sulfurizing step for blowing hydrogen sulfide gas into a nickel containing sulfuric acid aqueous solution to generate nickel-containing sulfides and a barren liquid, and the nickel-containing sulfides with the average particle size adjusted to a predetermined size or larger are added as seed crystals to the sulfuric acid aqueous solution. It is more preferable to adjust the average particle size of the nickel sulfides to be added as seed crystals to 55 μm or more.
