    摘要： A process for producing arsenous acid is disclosed. The reactants include an organic solvent containing 5 valent arsenic, a reducing agent and an additional component selected from the group consisting of water and an aqueous solution. The organic solvent containing 5 valent arsenic contacts and reacts with the reducing agent in the presence of the water or aqueous solution in order to directly produce arsenous acid from the organic solvent containing 5 valent arsenic. The process is a simple and economical process for producing arsenous acid.

    摘要： In a method for leaching gold from copper sulfides, the sulfide ores are first subjected to leaching of copper, thereby producing a leaching residue having 7.9% or less of the copper content. This leaching residue is mixed with a leach liquor, which contains the chloride ion and ferric ion and has 1.9 or less of pH.Gold and copper can be effectively leached from the copper sulfide ores. Ordinarily used oxidizing reagents such as hydrogen peroxide or nitric acid are not used. The gold, copper and iron can, therefore, be leached in a single process and by using an identical leaching liquor. The rate of gold leaching reaction can be enhanced by the co-presence of either copper or bromide ion or both together with the chloride and iron ion.

    摘要： The copper sulfide ore is leached in the halide bath without using a special oxidant but with the use of only air. The copper and gold in the copper sulfide ore can be leached at high leaching ratio.The treating steps are as follows. (1) Copper leaching process (CL). The raw material is charged into the first acidic aqueous solution, which contains cupric chloride, ferric chloride, 7 g/L of hydrochloric acid, and sodium chloride. The post-leach liquor contains copper in cuprous state ions and copper in cupric state ions. (2) Solid-Liquid separation step. The resultant solid and liquid of CL step are separated. (3) Air oxidation step (OX). Air is blown into the post solid-liquid separation liquor. The copper in cuprous state ions are oxidized to the copper in cupric state ions. The iron leached in the step (1) is oxidized. Simultaneously, the impurities leached in the step (2) are precipitated. (4) Copper extracting step (CEX). The copper is recovered from the post-liquor of the step (3) (5) Gold recovering step (AL). The residue separated in the step (2) is added to the leach liquor similar to that of the step (1). The steps (1) and (5) are carried out under the atmospheric pressure and at the temperature of boiling point or lower, while blowing air into the leach liquor.

    摘要： A process of leaching gold comprising the steps of: a) leaching copper from copper sulfide ore material that contains gold or contains silicate ore containing gold until the copper grade is reduced to 7.9 wt % or less; b) mixing the resulting material having a copper grade of 7.9 wt % or less with a gold leaching solution selected from the group consisting of a first solution containing chloride ions and ferric ions, and a second solution containing chloride ions and iron ions, the iron ions having been oxidized to trivalent ferric ions by air bubbled into the second solution; c) adjusting the pH of the gold leaching solution to 1.9 or less with stirring to leach at least gold in the material into the gold leaching solution by the oxidative activity of the ferric ions contained in the gold leaching solution, wherein the concentration of gold is reduced by selectively removing gold from part or all of the gold leaching solution during gold leaching. This process efficiently leaches at least copper and gold from a copper sulfide ore.

    摘要： In an image forming apparatus, a rotary developing device or revolver has a plurality of developing sections each storing a developer of particular color thereinside. The revolver is rotatable to sequentially move the developing sections to a preselected developing position so as to develop toner images sequentially formed on an image carrier. Toner cartridges are each removably mounted to the respective developing section. Only one of the cartridges located at a preselected replacing position can be pulled out and replaced. A toner cartridge is prevented from being accidentally mounted to the developing section located at the replacing position and whose cartridge has already been replaced.
