Copper Tailing an overview ScienceDirect Topics

The compaction characteristics of copper tailings are not clearly understandable from the existing data. In the standard Proctor test, copper tailings have a lower MDD and higher OMC than both CS and sand. However, in the modified Proctor test, the MDD and OMC of copper tailings are higher than those of both CS and sand.

Innovative Methodology for Sulfur Release from Copper

From Figure 3, the main mineral in the copper tailings was quartz, biotite, clinochlore, pyrrhotite, lepidocrocite, and sulfur. Therefore, the sulfur minerals in copper tailings, including pyrrhotite and natural sulfur, could be released by oxidative roasting. Table 1 Chemical composition of

Economic Potential for reprocessing Copper Mine Tailings

Four copper mine tailings in Chile were investigated for their elemental and mineral composition, in order to evaluate the potential for economic reprocessing. The sample material, taken for processing had Cu-contents between 0.1 and 0.5 %. Copper was abundant in various primary (mostly chalcopyrite) and secondary (cuprite, atacamite, b

Environmental Risks From Mine Tailings ThoughtCo

10/08/2018· Tailings from copper and uranium mining often produce measurable levels of radioactivity. Tailing Ponds . Some mining wastes become very fine after they have been ground up during processing. The fine particles are then generally mixed with water and piped into impoundments as a slurry or sludge. This method cuts down on dust problems, and at least in theory, the impoundments

Copper extraction Wikipedia

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.
