tailings in impoundments or free-standing piles, backfilling underground mine workings and open-pits, subaqueous disposal, and the most common method, the disposal of tailings slurry in impoundments. Modern tailings impoundments are engineered structures for permanently disposing of the fine-grained waste from mining and milling operations.

In response, mining engineers have developed clever ways of waste management, making the mining industry one of the few that actively recycle their own waste. Overburden is used for reprocessing, contouring land, and as a construction aggregate for buildings and roads. Mine tailings are reused for producing clay, tiles, glass, and concrete.

Converting Tailings Dumps into Mineral Resources Energy

Converting Tailings Dumps Into Mineral Resources Energy

The correct measurement of dry bulk density to account for moisture content is often overlooked in tailings dump Mineral Resource estimation. Often, an overly simplistic method is used to estimate the bulk density and this can cause significant errors in tonnage estimation and, consequently, an over estimate of metal content.

The tailings dams raised with upstream construction method require less volume of mechanically placed fill material beach sand tailings for raising of perimeter dikes, and are therefore economical in cost as compared to the tailings dams raised with the downstream and centreline construction methods Vick, 1990. Therefore, many
