The first method mentioned, high density thickened tailings (HDTT), is a process where the water content of tailings is decreased, which is beneficial in three ways: 1) it increases the amount of recoverable water, lowering the costs that come from evaporation and seepage during mining, 2) the lower amounts of liquid reduces …

Mining involves the processing of mined ore to separate valuable minerals, leaving behind huge volumes of waste tailings. Driven by mining volumes, globally generated tailings are estimated to total ~3.2 bn tons for copper and ~1.8 bn tons for iron per annum. Water conservation and the cost of tailings and reclamation are also …

Say a copper mine produced 1Mt of metal in 1999 at 90% recovery. The remaining 10% of copper, around 111kt, went to tailings. 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 …

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.
