    摘要： A process for the recovery of nickel and/or cobalt from a nickel and/or cobalt containing solution comprising: (i) contacting the nickel and/or cobalt containing solution with metallic particles of at least one metal that is more electronegative than nickel and/or cobalt thereby enabling a cementation process to occur between the nickel and/or cobalt in the solution and the metallic particles to produce a nickel and/or cobalt cementate; and (ii) separating the nickel and/or cobalt cementate from the metallic particles thereby producing a slurry including nickel and/or cobalt cementate.

    摘要： The invention relates to a method and apparatus for controlling a continuous metal removal in conjunction with a zinc preparation process, in which the metal removal is performed in one or more reactors (11a-c), in conjunction with the reactor, the redox potential (16a-c) and the acidity and/or basicity are measured, and based on the measurement results, the process variables (17a-c) of the metal removal are adjusted towards the desired direction. According to the invention, the redox potential measurements (16a-c) are performed from the sludge produced in the reactor in conjunction with the outlet pipe of the reactor outside the reactor, and the measuring instrument (16a-c) is purified at predetermined intervals.

    摘要： A process for recovering scandium economically with high efficiency by concentration and separation from an oxide ore containing nickel and a small amount of scandium as well as a large amount of iron and/or aluminum comprises the steps of acid leaching the oxide ore under a high-temperature, high-pressure oxidative atmosphere while restraining leaching of the iron and/or aluminum, thereby selectively leaching substantially all nickel and scandium from the ore, recovering the nickel from the resulting leaching solution as a precipitated sulfide while not precipitating the scandium as a sulfide but leaving the total amount thereof in the solution, and then adjusting the pH of the solution with a precipitant to recover the scandium from the solution as a high-concentration scandium hydroxide or carbonate by concentration and separation.

    摘要： A nickel recovery process capable of decreasing nickel remaining in a byproduct by recovering nickel from the byproduct of electrolytic nickel manufacturing process by chlorine-leaching, and also, capable of simplifying a cementation step simultaneously, is provided. In a nickel recovery step S60, a nickel recovery step S70 and a nickel recovery step S80, nickel is recovered in each step from S 0 slurry, residue flaker and chlorine-leached residue, which are byproducts of electrolytic nickel manufacturing process by chlorine-leaching, by using an aqueous solution containing 80 g/L to 390 g/L of chlorine and 30 g/L to 70 g/L of copper.
