There is provided a method for separating an arsenic mineral from a copper-bearing material containing arsenic, such as a copper ore or a copper concentrate, to obtain a copper concentrate with low arsenic grade.The method for separating an arsenic mineral from a copper-bearing material by flotation includes adding a flotation agent containing a depressant, a frother, and a collector to a slurry composed of a copper-bearing material containing arsenic, and blowing air into the slurry to float a copper concentrate, wherein the depressant is sodium thiosulfate. The sodium thiosulfate is preferably added in an amount of 10 kg or more and 200 kg or less in terms of sodium thiosulfate pentahydrate per ton of copper-bearing material to be subjected to flotation. Further, the oxidation-reduction potential of the slurry to be subjected to flotation, as measured against a silver/silver chloride reference electrode, is preferably −10 mV or more and 50 mV or less.
摘要:
A liquid chamber receives liquid flows from a liquid receiving unit. A first urging member urges a deforming portion of the liquid chamber. A lever provided on the liquid container side increases the displacement of the deforming portion. A sensor detects the displacement. A transmitting member transmits the increased displacement to the sensor. A second urging member provided on a liquid consuming apparatus side urges the transmitting member. When the liquid container is installed in the liquid consuming apparatus, the transmitting member comes in contact with the lever member due to the urging force of the second urging member, and the lever member is pushed against the deforming portion. In this manner, it is possible to divide the liquid detection system into the liquid consuming apparatus side and the liquid container side.

A production process of a thick-film tape-shaped RE-type (123) superconductor having a high critical current value. The production process has the steps of providing a composite substrate having Gd2Zr2O7 and CeO2 stacked in that order onto a Hastelloy substrate, coating a raw material solution prepared by dissolving a trifluoroacetate of Y and Ba and a naphthenate of Cu onto the composite substrate, heat treating the coated composite substrate by calcination, then subjecting the calcined assembly to intermediate heat-treatment at a temperature below the temperature of heat-treatment for superconductor production, and then heat treating the assembly in an argon gas atmosphere under conditions of highest heating temperature 760° C., water vapor partial pressure 13.5%, and oxygen partial pressure 0.09% for superconductor production to produce a tape-shaped RE-type (123) superconductor having a YBCO superconducting film having a thickness of more than about 2 μm.

A cartridge includes a casing, a printing material containing portion, a printing material flow path and first and second insertion holes formed in a front face of the casing. A rod used for detection of the out-of-printing material state is inserted into the first insertion hole, and a printing material supply tube is inserted into the second insertion hole. The first insertion hole is located on the front face at a middle position between a first side face and a second side face of the casing.

A method of manufacturing a tape-formed oxide superconductor, in which a tape-formed wire material (6 in FIG. 1) is extended between a pair of reels (5a and 5b). Besides, a reactive gas is supplied form the gas supply ports of a reactive gas supply pipe (3a) vertically to the upper side film surface of the tape-formed wire material (6), so as to react the film body of this tape-formed wire material into a superconducting layer, while at the same time, a gas after the reaction is discharged from the gas discharge ports of discharge pipes (4a and 4b) for discharging the gas after the reaction. Likewise, the reactive gas is supplied vertically to the lower side film surface of the tape-formed wire material (6), so as to react the film body of this tape-formed wire material into a superconducting layer, while at the same time, the gas after the reaction is discharged from the gas discharge ports of discharge pipes (4c and 4d) for discharging the gas after the reaction. Even when the tape-formed wire material (6) is large in area, the tape-formed oxide superconductor has superconducting characteristics being uniform in it widthwise direction, and it can be manufactured at high speed.

A printing apparatus includes a recording head that prints an image and an ink cartridge that stores ink to the recording head. The ink cartridge includes an ink pack and an ink-end sensor that detects an ink-end point based on the pressure of ink supplied from the ink pack. The ink pressure corresponding to the ink-end point detected by the ink-end sensor is set to a first pressure that is the minimum pressure near an outlet of the ink cartridge at which the recording head can print an image of predetermined quality. A determining unit permits starting of a printing or cleaning operation in response to a command issued before the ink-end sensor detects the ink-end point and prohibits starting of a printing or cleaning operation in response to a command issued after the ink-end sensor has detected the ink-end point.
