ICMM About tailings

About tailings. Tailings is a common by-product of the metals and minerals recovery process. It usually takes the form of a liquid slurry made of fine metal or mineral particles and water – created when mined ore is crushed and finely ground in a milling process. From the mill, the tailings is typically pumped to storage facilities which are ...

If the average copper price in 1999 was US$1,500/tonne then that 10% represented US$166.5 million of metal. Fast forward 20 years and at today’s price, US$5,842/tonne, if that material could be reprocessed and an extra ...

CFD-PBM modelling of tailings flocculation in a lab-scale ...

In mineral processing thickeners, flocculation is a dynamic balance between aggregation and breakage. The process variables (e.g. turbulence dissipation rate, flocculant dosage, and slurry viscosity) that has a vital impact on floc breakage are taken into account in this flocculation modelling, and the breakage kernel is expressed as Eq. 19.
