Glencore’s aim is to run the processing plant as efficiently and stable (stability enhances metal recovery) as possible, with the most cost-effective reagent addition rates.
Glencore’s McArthur River Mine (MRM) is a world-class zinc-lead mine with a long future ahead of it. Operating since 1995, MRM is one of the world's largest zinc resources and a key operation in Glencore's global portfolio. MRM produces zinc, lead and silver from our open cut mine, which is then processed and stored onsite before being transported to Bing Bong Loading Facility and shipped to our customers all over the world.
Conventional crushing / grinding and flotation processes produce three products; a bulk zinc-lead concentrate, zinc concentrate and lead concentrate. The main refinement steps are the rougher and cleaner, during which copper sulphate reagent is added to the flotation process as an activator to promote flotation separation of the zinc bearing mineral, sphalerite (zinc sulphide) from the ground ore. Xanthate reagent is also added as a collector in the selective flotation of galena (lead sulfide) to separate it from the sphalerite.
Glencore’s aim is to run the processing plant as efficiently and stable (stability enhances metal recovery) as possible, with the most cost-effective reagent addition rates. This competition is the first step toward building an optimisation algorithm that can help us improve the process.
OreFox is building a model to accurately predict the rougher zinc recovery and the final zinc recovery for each hourly interval in the data set. This prediction will be compared with the actual recovery as recorded by our continuous OSA monitoring system.
