Cashing in – on the Calciner

Khalid Hammouch can tell you about heat. Try 800°C. That’s the temperature of a calciner in full operation, during one of the steps in milling uranium ore. Even in standby mode, the calciner registers a cool 300°C. What else can the heat be used for?

The answer earned Khalid and his teammates a trip to Paris, along with 19 other teams from China, India, Germany, the US and France. At stake was first prize in the AREVA group’s Sustainable Development Awards. “Cashing in on the Calciner” presented a simple idea: add a heat exchanger to the calcination process. Although it didn’t win the prize, the concept earned the admiration of the judges and others, who were left pondering, “Why didn’t I think of that?”

Monitoring Effluent Water Quality – McClean Lake

AREVA Resources’ network of policies, procedures and monitoring programs ensures that emissions from mining and processing remain as low as reasonably achievable. The graphs below show the significant difference between regulatory limits and the sampling results at the JEB mill and Sue mine water treatment plants at McClean Lake.

We are always striving to minimize our effect on the environment and our use of resources. One method is to monitor a number of indicators to see how we are doing and where there is room for improvement. Here are some of the results:
