Recycling Copper Mine Tailings trinitytrade.in

Recycling Of Historical Mining Waste A New Business . Tailings of the Kilembe copper mine, Uganda, containing 80 pyrite, resulted in important acid mine drainage. To cope with this, tailings were fed to a tank bioleaching process, resulting in a full conversion of sulphides, hereby removing the source of acid mine drainage. At the same time, 1.38 of Co was recovered from the materials.

Copper Tailing an overview ScienceDirect Topics

The properties of copper tailings, a fine-grained residue waste produced from beneficiation of copper ore, and their effects on the properties of bituminous mix were studied by Oluwasola et al. (2014, 2015). The copper tailings were used at 20% content as a fine granite replacement for

Recycling of copper tailings as an additive in cement

Abstract Increasing demands for copper and copper allied products have made the processing of low grade ores with high volume waste output unavoidable. Presently, billions of tons of copper tailings can be found in major copper producing countries. The impact of copper tailings at 0%, 5% and 10% addition level by mass of cement on the fresh and hardened properties of mortars were determined.
