A robust ORP sensor for high temperature hydrometallurgy

UBC开发了一种强大的电化学设备，用于测量湿法冶金氧化过程中遇到的极端环境的氧化还原电位（ORP）。氧化还原电位是任何氧化过程中的关键工艺控制参数，但由于现有技术不可靠，目前尚未对其进行原位监测。虽然该设备的主要目标是高温和高压氧化过程，但该探头几乎可用于所有湿法冶金操作。探头设计简单而坚固-确保其性能优于所有当前可用的技术。该探针还可以测量与ORP平行的原位铁浓度。该提案提出了一项计划，以开发在采矿业广泛使用的探头。

UBC has developed a robust electrochemical device to measure the oxidation-reduction potential (ORP) of the extreme environments encountered in hydrometallurgical oxidation processes. The ORP is a critical process control parameter in any oxidation process but it is not currently monitored in-situ because existing technology is unreliable. While the main target for the implementation of this device is high temperature and high pressure oxidation processes, the probe can be used in virtually all hydrometallurgical operations. The probe design is simple and robust - qualities that ensure that it outperforms all currently available technologies. The probe can also measure in-situ iron concentration in parallel to ORP. This proposal sets out a plan to develop the probe for widespread use in the mining industry.
