  • Publication number: 20220355313
    Abstract: Provided is a mineral processing method that can efficiently separate a copper mineral and a molybdenum mineral. A mineral processing method includes a conditioning step of adding a disulfite to a mineral slurry containing a copper mineral and a molybdenum mineral and a flotation step of performing flotation using the mineral slurry after the conditioning step. By selectively enhancing hydrophilicity of the copper mineral with the disulfite, the hydrophilicity between the copper mineral and the molybdenum mineral can be differentiated. Thus, the molybdenum mineral can be selectively floated, and the copper mineral and the molybdenum mineral can be efficiently separated.

    Abstract: Disclosed herein is a method for separating an arsenic mineral from a copper-bearing material, including the steps of grinding a copper-bearing material containing arsenic, adding water to the copper-bearing material to prepare a slurry, and adding a flotation agent including a depressant, a frother, and a collector to the slurry and blowing air into the slurry for performing flotation to obtain a copper concentrate, wherein the depressant is a chelator. As the chelator, a polyethyleneamine or the like is used. Particularly, when triethylenetetramine is used as the chelator, the amount of triethylenetetramine to be added is preferably 1 to 10 equivalents relative to the amount of soluble copper generated by oxidation of the copper-bearing material, and the pH of the slurry is more preferably adjusted to 7 or more but 8 or less before the slurry is subjected to the flotation.

  • Patent number: 8116626
    Abstract: In an optical transmission apparatus, levels of signal lights obtained by demultiplexing a WDM signal and corresponding to channels are detected, based on which a channel in which a signal is transmitted and a channel in which no signal is transmitted are determined. An attenuation amount of a channel in which no signal is transmitted in a predetermined range from the channel in which the signal is transmitted is set to a value equal to an attenuation amount of the channel in which the signal is transmitted. An attenuation amount of a channel in which no signal is transmitted out of the predetermined range from the channel in which the signal is transmitted is set to a value larger than the attenuation amount of the channel in which the signal is transmitted. The signal lights are attenuated based on the values and multiplexed.

  • Patent number: 8021495
    Abstract: Provided are a simple and inexpensive cleaning apparatus and a method for cleaning capable of effectively cleaning the outer wall surface of a pipette. A pipette to be cleaned is positioned in a concave portion of the cleaning apparatus, and a cleaning liquid passed through inside of the pipette strikes an inner circumferential surface of the concave portion and bounces therefrom to splash against the outer wall surface of the pipette, thereby cleaning the outer surface. With above arrangement, without using an ejection apparatus of cleaning water, effect equivalent to that with the ejection apparatus can be attained. Furthermore, both the inner wall surface and the outer wall surface of the pipette can be cleaned by a single operation using the same cleaning water, thereby attaining easy internal cleaning work and short cleaning time.
