tailings of copper ore flotation from OEP. They were installed at three heights in relation to the axis of the pipeline, i.e. above the axis, in the axis and below the axis.

They are dewatered and sent to tailing ponds. Flotation is preceded by crushing and grinding the mined Cu ore to small (∼100 μm diameter) particles. Its use has led to adoption of smelting processes that efficiently smelt finely ground solids. A video of mining and mineral processing may be seen in The Mining Process at Copper Mountain Mine ...

The invention belongs to the field of mineral processing, relates to a beneficiation method, and particularly relates to a method of sorting copper sulfide ore flotation tailings. The method comprises the following steps: A, the tailings with copper and sulfur separated are dewatered through a thickener, wherein the content of the sulfur in the tailings is more …

The lead–zinc ore is a typical low-grade complex polymetallic sulphide ore. Its typical mineralogy is characterized by a high content of cryptocrystalline graphite, low content of lead, zinc, and copper, and fine grain size. However, the aggregation size of sulfide mineral aggregations is coarse, and the symbiotic relationship is relatively simple. …

Keeping Up with Demand: Copper Tailing Reprocessing. Copper is a key resource in modern industry and society. However, copper is finite like all natural resources, and increasing demand for this material depletes global copper reserves. Recovering copper is a crucial strategy to keep up with demand. One approach is to reprocess …

Flotation tailing is a problematic mining waste, because contains sulphides that exposed to oxidising conditions generate acidic drainage and the subsequent metal mobilisation. ... (2019) reports a variant of the technology for the joint processing of pyrite flotation tailings from the tailing dump and copper-zinc concentrates. This approach ...

The copper ore treatment process in RTB Bor produces significant amounts of mine waste material such as: mining waste, flotation tailing and copper slag (Stanojlovic et al., 2014). Mine waste can be defined as waste materials that result from the ore exploration, mineral and pyrometallurgical processing.

The Denver cell test with a porphyry ore shows a selective flotation with IPETC at a pH of 11 with a low collector dosage (5 g/ton), achieving recoveries of 92% covellite and 39% pyrite. Also, recoveries of 85% covellite and 75% pyrite were observed for a bulk flotation with IPETC at pH = 8 at the same collector dosage.

of gold and copper were studied. The present study aims to provide a non-cyanide and effective approach for the recovery of gold and the associated copper from low-grade gold sulfide tailings. 2. Materials and Methods 2.1. Materials The sample used in this study was a sulfide cleaner flotation tailing, obtained from the flotation process of ...

The pyrite grade in the fresh tailing sample and in the flotation product was determined indirectly from the content sulfur, copper and iron. Calculations carried out considering the elemental chemical composition presented in Table 1 and the mineralogical species that contained sulfur, identified by the XRD analysis, allowed to determine that …

The concerns for sustainable mining development need broader consideration of a essential balance of social, economic risks and environmental facets for industry as whole (Mudd, 2010). Considering the price of copper in the world and the environment protection policy of China, a possible recovery of copper from tailings by …

The mining industry has faced significant challenges to maintaining copper production technically, economically, and environmentally viable. Some of the major limitations that must be overcome in the coming years are the copper ore grade decline due to its intense exploitation, the increasing requirements for environmental protection, and …

The mass production of flotation tailings has become a serious risk to the environment. Re-concentration of tailings is one of the best ways to solve this problem, which requires a better understanding of flotation tailings. In the present work, flotation kinetics, timed-release flotation, X-ray diffraction (XRD), Fourier transform infrared …

1. Introduction. Coal is an important energy source in some countries, especially in China, 1 Australia, 2 Poland, 3 and India. 4 The proportion of fine coal in the raw coal significantly increases with the high mechanization of coal mining technology. The separation of fine coal has become a severe challenge for the coal industry. 5,6 Froth …
