Abstract: A process of water-granulating copper smelting slag can readily suppress elution of As from the copper smelting slag. A process of water-granulating a copper smelting slag with granulation water in a circulating system, includes granulating the copper smelting slag with the granulation water; settling suspended solids from the granulation water circulating in the system in a settling tank followed by discharging part of the granulation water through the settling tank from the system; and feeding supplementary water having a concentration of As of 0.01 mg/L or less into the system in such an amount that the total amount of the granulation water circulating in the system is kept constant; wherein the amount of granulation water discharged through the settling tank is such that As eluted from the copper smelting slag after water granulation is 0.01 mg/L or less.

Abstract translation: 铜熔炼渣的造粒工艺可以很容易地抑制砷从铜熔渣中的溶出。 在循环系统中用造粒水对铜冶炼炉进行造粒的方法，包括用造粒水造粒铜熔渣; 从系统中循环的造粒水在沉淀池中沉淀出悬浮固体，然后将部分造粒水通过沉淀池从系统中排出; 将浓度为0.01mg / L以下的补充水补给体系中循环的造粒水的总量保持不变的量; 其中通过沉降槽排出的造粒水的量使得在水造粒后从铜熔炼炉渣洗脱出的As为0.01mg / L以下。

Abstract: A corrosion evaluation device for performing a quantitative evaluation of corrosion by measuring a quantity of decrease in the thickness of a magnetic material which is covered by a non magnetic material or a magnetic material which is not covered by a non magnetic material which includes: a magnetic field generating device for generating such a magnetic field that includes the magnetic material in a magnetic path, a Giant Magnet-Resistive effect (GMR) sensor provided with a GMR sensor for detecting a magnetic flux leakage with regard to the magnetic material and converts a change in the magnetic flux into an electrical signal, a thickness reduction calculation portion for calculating a quantity of decrease in the thickness of the magnetic material based on the electrical signal. The corrosion evaluation device precisely performs a quantitative evaluation of corrosion even when the magnetic material, which is to be evaluated, is covered by a non magnetic material.
