According to Table 2, copper in the ore primarily exists in the form of copper sulfide, with an oxidation rate of 19.14 %, classifying it as mixed-type copper ore. The content of native copper sulfide accounts for 42.97 %, while the content of secondary copper sulfide is also significant, reaching 37.89 %.Secondary copper sulfide is formed by ...
We want to buy buy copper ore, we are Asian buyer, high quality copper ore, malachite, antimony ore, gold ore etc are needed. ... Gangue from copper mining typically contains silicate minerals and oxides. In some cases these tailings have been retreated as the technology for recovering copper has improved. The average grade of copper ores in ...
Characterization of the Itakpe iron ore tailings showed that it has pozzolanic properties, and can be used as a retarder for hot-weather concreting, and could be used to predict relationships of IOT-OPC concrete. An evaluation of the Itakpe iron ore tailings (IOT) for concrete production has been carried out using the material to replace sand and cement, in proportions …

In the future, we can consider more ore types, such as iron ore, nickel ore, lithium ore, etc. for bio-passivation combined solid waste treatment of AMD, and conduct a more in-depth study on the thickness and uniformity of the bio-passivation layer generated during the bio-passivation of copper sulfide mine tailings.
Iron Ore Tailings (IOT) are the waste slag resulted from iron ore mines. Large amount of Iron Ore Tailings (IOT) have been generating every year posing serious environmental problems, large production of cement everyday resulting the emission of CO 2 and increase in the consumption of river sand for construction activities making the river beds over-exploited.
The flotation process appears to include some differences, as the copper concentration in the tailings emitted in the 1970's were higher (typical value ca. 470 ppm Cu (Paulsen et al., 1977)) than analyses of the fabricated tailings produced in 2015 (approximately 200 ppm), or the copper content in the ore has changed. The elements Ag, Ba, Ca ...
In the 21st century, and average copper grade ore might be -0.6% copper. a) How many pounds of 0.6% grade copper ore needs to be mined in order to obtain 420 pounds of copper? Show your work. 2.52 pounds (420x0.6) = 252/100 = 2.52 pounds b) Tailings are the waste (ground rock and process effluent) left over from the mining process.
Iso-floatability flotation process was further applied to the magnetic tailings, achieving a copper grade of 28.37 wt.% and a recovery ... and 25.21%, respectively. Therefore, this study provides an available separation of copper-zinc-lead minerals from iron tailings at Marcona Iron Ore Mine based on process mineralogy, thereby giving a prior ...

Sun. 2021. "Recovery of γ − Fe 2 O 3 from copper ore ...
the use of a real effluent obtained from the leaching of sulfide ore tailings is studied for the biosynthesis of copper nanoparticles. For this purpose, the bacterial biomass of Pseudomonas stutzeri was used as a bioreducing agent. The leaching of the chalcopyrite-bearing tailings achieved a copper recovery of 50% in 8 h, thanks to sodium
