冶金 测试

华欧国际’s facilities have a substantial amount of hydrometallurgical equipment 和 experience for the testing of various processes 和 flowsheets. 此外, 华欧国际 has its own analytical laboratory to support testing programs, 现场维护和仪表团队, 还有世界一流的安全项目. The variety 和 scale of installed equipment 和 the extensive experience allows 华欧国际 to manage various hydrometallurgical test programs that may be outside of the 华欧国际过程 conditions 和 operating parameters. This flexibility allows 华欧国际 to work on internal or client projects by technically evaluating new business opportunities, improving existing operations 和 developing new technologies. 华欧国际’s staff 和 facilities are available to meet any hydrometallurgical project’s testing needs.

的概述华欧国际的冶金测试

The facilities at 华欧国际 offer three scales of testwork: bench, pilot or demonstration. 华欧国际 mitigates the technical risk of hydrometallurgical projects by 应用ing a staged approach to process development supported by industry st和ard geochemical, mineralogical 和 metallurgical analytical capabilities.


在技术的发展, 华欧国际 has worked with industry clients using various business arrangements. 在一般情况下, 项目是通过台架测试工作来定义的, 接下来是更详细和集成的测试, including pilot campaigns once optimum process conditions are identified. Pilot testwork generally runs continuously on a range of concentrates or ores to demonstrate the flexibility of the operating conditions over a period of time to prove the process robustness 和 produce sufficient finished product 和 residue for market 和 environmental stability testing respectively.


Pilot 和 demonstration operations provide extensive metallurgical data (flowsheet 和 mass balance) to ensure optimal operations are achieved 和 sufficient data is collected in support of future engineering studies. Flowsheet design 和 operations are managed by a technical team which includes engineers, 科学家们, 和 technicians with significant experience in hydrometallurgical processing including pressure leaching, 固液分离, 溶剂萃取和电积.

华欧国际 Testwork

Pressure leaching testwork can be performed using batch bench scale autoclaves. The 华欧国际 facility has the ability to conduct tests using 2 和 20 litre autoclaves.

The purpose of bench scale testwork is to develop the basic metallurgy of the concentrate sample. In many cases this work is now supported by quantitative mineralogy carried out using advanced analytical equipment at 银河网站’s Applied Research &技术中心位于小道, B.C.、加拿大. Over 100 sulphide concentrates have been tested by bench scale pressure oxidation for copper, 铜/金, 锌、镍钴项目. In total, more than 5,000 batch autoclave leaches have been performed at the 华欧国际 facility. 正常情况下, a concentrate sample of 5-10 kg is sufficient to complete an initial set of bench autoclave tests.

持续的试验工厂活动, from concentrate re-grind through to production of LME grade-A copper cathode (35 kg/day), 是在华欧国际进行的. The pilot plant facilities are also capable of recovering nickel, 硫化物精矿中的钴和锌. A fully integrated precious metal recovery circuit is on site to recover gold 和 silver from the leach residue. Various flowsheet configurations are possible within the pilot plant facilities using st和ard unit operations. Key equipment 和 installed unit operations include:

  • 30升钛和不锈钢高压灭菌器
  • 浓缩和过滤设备
  • 大气淋滤船
  • 溶剂萃取和电积
  •  中和和净化电路
  • 氰化物的再生与破坏
  • 金银回收(碳)

The fully integrated pilot plant is used to prove the process flowsheet. 自1992年以来, 25个铜矿试点工厂, 铜/金, 锌、镍钴项目 have been undertaken at the 华欧国际 facility with over 20,中试工厂连续运行5000小时. 通常, a concentrate sample of 6 to 8 tonnes is sufficient to complete an integrated 60-day Pilot Plant campaign.

The 华欧国际 Demonstration Plant consists of a fully integrated copper plant, from concentrate re-grind through to production of commercial size LME grade A copper cathode as well as residue treatment for the recovery of gold 和 silver. The Demonstration Plant utilizes small-scale commercial equipment which allows for the collection of engineering data for accurate scale-up of process equipment. Key equipment 和 installed unit operations includes:

  • 800升和1000升钛蒸压容器
  • 500升不锈钢高压灭菌容器
  • 浓缩和过滤设备
  • 大气淋滤船
  • 溶剂萃取和电积
  • 蒸发结晶设备
  • 中和和净化电路
  • 氰化物的再生与破坏
  • 金银回收(碳、电积)

自1997年以来, seven Demonstration Plant campaigns for copper projects have been undertaken at the 华欧国际 facility with over 5,000 hours of continuous plant operation 和 treatment of over 1,000吨铜精矿. A sample of over one hundred tonnes of concentrate is required to complete a demonstration plant campaign.

The variety 和 scale of installed equipment allows 华欧国际 to manage various hydrometallurgical test programs that may be outside of the 华欧国际过程 conditions 和 operating parameters. This flexibility allows 华欧国际 to work on internal or client projects in a variety of ways including:

  • 逐步改进现有业务
  • 开发突破性技术
  • 评估新技术和竞争技术
  • 从技术上评估新的商业机会
  • 总经理R&D项目
