Calcite, rutile and chalcopyrite are the accessory minerals in the tailings. Table 3 lists the main and accessory minerals in the Tz23 drill core samples. Quartz and sericite are the most...

A complete characterization of the copper tailing sample was carried out as chemical and mineralogical composition and size distribution. The ... (Cu 5 FeS 4 with Cu/S = 2.48) and chalcocite (Cu 2 S with Cu/S = 3.96) minerals in the composition together with chalcopyrite (CuFeS 2), which Cu/S is 1.14. The true density of copper tailing was 3. ...

The low NAG pH obtained with sample III (5.30) was due to its high pyrite content (0.30 wt%) in comparison with the results obtained with sample I (NAG pH of 8.15 and 0.10 wt% of pyrite), and ...

The formulas are based on assays of samples, and the results of the calculations are generally accurate— as accurate as the sampling, assaying, and crude ore (or other) tonnage on which they depend. Two-Product Formulas. The simplest case is that in which two products only, viz., concentrate and tailing, are made from a given feed.

These tailings are rich in sulphide minerals particularly pyrite and chalcopyrite. Oxidation of these minerals produces the well-known problem of acid mine drainage. In this research, a depth …

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 fresh tailings …

The new-type tailing dump of copper-pyrite ore concentrator contains basic minerals: up to 1% of pyrite and chalcopyrite; up to 2% of sphaleriite, minor amount of galena, pyrrhotine, arsenopyrite, magnetite, ilmenite, tennantite, tellurium vismuthite, and freibergite. The main barren mineral is quarts within 2–61% in content.

This study, carried out in tailings from two sediment-hosted stratiform copper deposits in the Lublin-Głogów Copper District in Poland (Kupferschiefer-type deposit) and Zhezkazgan (cupriferous sandstone-type …

The in situ samples included chalcopyrite froth (CuR1), chalcopyrite tailing (CuJ), sphalerite froth (ZnR), sphalerite tailing (ZnJ), pyrite forth (SR1), and pyrite tailing (SJ). Mineral concentration series were created to simulate a situation, where the mineral levels of the process samples have wider fluctuation range.

behind as the tailing products. Often it is better to float the gangue minerals and recover the valuable minerals from the tailing product. Due to the fact that high grade ores are scarcer than low grade ores, the flotation process constitutes an economically feasible method to recover rich concentrates from the low-grade ores.

Copper slag tailings, primarily stemming from pyrometallurgical processes, predominantly consist of a silicate matrix [].It is estimated that 2–2.2 tons of slag tailing are generated for every ton of copper produced, and approximately 40 million tons of slag are generated from global copper production [2,3,4].Unfortunately, slag tailings are often directly …
