International Journal for Research in Applied Science

Abstract In India, 4 million tons of copper tailings produce every year, out of which 25,000 tons produce in Khetri Copper Mines, Khetri, and Rajasthan. This research was undertaken to study the effects of copper mine tailings as a replacement of sand on the properties of concrete and also to bring the alternative aggregates for the future.

CNRL plans to implement another new tailings treatment process during Horizons next phase. As part of this new process, cyclones will remove the water from the coarse sand, and thickeners will remove the water from the fine clays, silts and sand. The dewatered streams will then be combined with waste CO 2 . The tailings that result will be deposited in the tailings disposal area where even more water will be

Study of the settling characteristics of tailings using

In this study, an attempt was made to measure the settling characteristics of tailings using nuclear magnetic resonance (NMR) technology with a bimodal compositional detection method. This technique allows for accurate quantification of the oil and water content in a sample within a relatively short time (under 15 minutes).

Mining

Mining is the extraction of valuable minerals or other geological materials from the earth, usually from an orebody, lode, vein, seam, reef or placer deposit.These deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.
