CESL冶金测试概述

The facilities at CESL offer three scales of testwork: bench, pilot or demonstration. CESL mitigates the technical risk of hydrometallurgical projects by applying a staged approach to process development supported by industry standard geochemical, mineralogical and metallurgical analytical capabilities.

In the development of technologies, CESL has worked with industry clients using various business arrangements. In general, a project is defined through bench testwork, followed by more detailed and integrated testing, 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 and produce sufficient finished product and residue for market and environmental stability testing respectively.

Pilot and demonstration operations provide extensive metallurgical data (flowsheet and mass balance) to ensure optimal operations are achieved and sufficient data is collected in support of future engineering studies. Flowsheet design and operations are managed by a technical team which includes engineers, scientists, and technicians with significant experience in hydrometallurgical processing including pressure leaching, solid-liquid separation, solvent extraction and electrowinning.

CESL Testwork

Pressure leaching testwork can be performed using batch bench scale autoclaves. The CESL facility has the ability to conduct tests using 2 and 20 litre autoclaves.

台面验证的目的是开发浓缩物样品的基本冶金。在许多情况下，现在使用位于加拿大普拉斯的TRAIN AVER AVECTION＆TECHNAL CENTROMENTION CANDE，B.C.的Support Compress＆Technology Center进行了定量矿物学的定量矿物学支持。万博手机版注册账号通过铜，铜/金，锌和镍钴项目的台式压力氧化已经测试了超过100种硫化物浓缩物。总共在CESL设施中进行了超过5,000分批式高压灭菌浸出。通常，5-10kg的浓缩样品足以完成一组初始的台式高压釜测试。

Continuous pilot plant campaigns, from concentrate re-grind through to production of LME grade-A copper cathode (35 kg/day), are conducted at CESL. The pilot plant facilities are also capable of recovering nickel, cobalt and zinc from sulphide concentrates. A fully integrated precious metal recovery circuit is on site to recover gold and silver from the leach residue. Various flowsheet configurations are possible within the pilot plant facilities using standard unit operations. Key equipment and installed unit operations include:

30升钛和不锈钢高压釜
增厚和过滤设备
大气浸出船舶
溶剂萃取和电灌输
Neutralization and purification circuits
氰化物再生和破坏
金银回收（碳）

The fully integrated pilot plant is used to prove the process flowsheet. Since 1992, 25 Pilot Plant campaigns for copper, copper/gold, zinc and nickel-cobalt projects have been undertaken at the CESL facility with over 20,000 hours of continuous Pilot Plant operation. Typically, a concentrate sample of 6 to 8 tonnes is sufficient to complete an integrated 60-day Pilot Plant campaign.

The CESL 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 and 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 and installed unit operations includes:

800 and 1,000 litre titanium autoclave vessels
500升不锈钢容器
增厚和过滤设备
大气浸出船舶
溶剂萃取和电灌输
Evaporation and crystallization equipment
Neutralization and purification circuits
氰化物再生和破坏
金银恢复（碳，电瓦宁）

自1997年以来，在CESL设施中，在CESL设施中进行了七种演示厂竞选活动，超过5000小时的连续植物操作，治疗超过1000吨铜精矿。需要超过一百吨浓缩物的样品来完成演示工厂运动。

The variety and scale of installed equipment allows CESL to manage various hydrometallurgical test programs that may be outside of the CESL Process conditions and operating parameters. This flexibility allows CESL to work on internal or client projects in a variety of ways including:
