Objectives of the commitment
Develop a system based on the integration of data from several sources (from processing operations and mine water treatment systems to visual inspections) using device to device communications, that monitors the above mentioned waste flows, triggering alerts and recommendations allowing the separate collection of slurries enriched with metals for further processing.
Contribute to safe long term maintenance of tailing dams.
Test and adapt equipment for collection of data from mining waste flows feeding tailings dams.
Description of the activities
A tailings dam is an earth-fill embankment dam used to store waste from mining operations after separating the valuable fraction from the uneconomic fraction of an ore. The waste is often in the form of slurry, and its composition depends on the nature of the rock and minerals being mined and on recovery processes used.
Tailing dams are designed for permanent containment of mining wastes but, especially in metal mines, may contain large quantities of metals and other valuable elements that could have been recovered. This happens for two main reasons: 1) no recovery process is 100% efficient, capable of capturing all target elements mined; and 2) changes in the chemical nature of the run of mine materials unbalance the line treatment process and, until the adequate readjustment in the process is made, the waste flow carries valuable elements that should have been captured.
Unfortunately, due to geological variety and the continuous nature of mineralsâ processing plants, the reason 2) above is frequent, and mineral processing is a dynamic (continuously rebalancing) activity, in an effort to accommodate feed-in changing conditions.
In this context, the routing of metals, or other valuable elements that could have been recovered, to tailing dams is frequent. This not only poses problems to mine profitability, but also depreciates the tailings dam itself, diminishing its capacity and lifetime. For society, this impact is also negative, fostering the need for more mines and bigger and difficult to maintain tailing dams, with the correspondent economic, environmental and social losses.
The TailingsDamScavenger system will integrate real time data from mineral processing, water treatment and waste monitoring with data from instruments and inspection activities to define response mechanisms allowing the separate collection of slurries enriched with metals and alert levels that will optimize materials recovery, contributing to increase the lifetime and safety of tailing dams. This system will run in a web base application enabling, from the start, combination of data gathering using device to device communications and data treatment using predictive heuristics. This will support the definition of several levels of warning, alert messages and actions, tailored to different stakeholders.
Description of the expected impacts
TailingsDamScavenger will enable the recovery of metals and other valuable materials from mine waste slurries, contributing to increase the efficiency of industrial ore treatment processes. This will bring positive impacts on mining companiesâ competitiveness, but also on society and environment policies, by diminishing the need for new mines and more and bigger tailing dams.
