• Copper Leaching Method Metallurgist & Mineral Processing

    In leaching roasted mill tailings the consumption of acid appears to be small—about 50 lb. acid per ton of tailings handled—even with very fine material. This illustrates the benefit derived from roasting substances containing colloids, such as mill slimes, when the copper

The dump consists of the concentrator tailing discharge, over a period extending to the present date. According to daily samples taken during that period, the copper content is about 0.64 per cent, and the silver 0.48 oz. per ton. The peak of the dump, or the point where the tailing is discharged, carries about 0.75 per cent, copper, while down toward the toe, and where present excavation is taking place, the...

  • PROCESS DEVELOPMENTS AT TAILINGS LEACH PLANT Gift C

    1.0 TAILINGS LEACH PLANT, AN OVERVIEW From inception, Tailings Leach has been developed in three stages. The operation started with leaching of low-grade tailings using strong sulphuric acid followed by solution recovery and cementation of copper. The capacity then was about 1000 tonnes of copper per month.

    Most copper ores contain only a small percentage of copper metal bound up within valuable ore minerals, with the remainder of the ore being unwanted rock or gangue minerals, typically silicate minerals or oxide minerals for which there is often no value. In some cases, tailings have been retreated to recover lost value as the technology for recovering copper has improved.
