1.1. What Are Mine Tailings? An Initial Scope in an Uncertainty and Complex World. The initial step in mineral processing involves crushing and grinding ore to produce a suitable particle size for further metallurgical processing using physical and chemical separation methods [].Physical separation processes take advantage of the …

Mining involves processing of mined ore to capture valuable minerals, which in turn produces large volumes of tailings. The annual global tailings production is currently estimated to be at the range of 10-12 billion tons/annum and increasing. Therefore, it's important to reshape tailings management and accelerate the positive change.
