The IsaMill is an energyefficient mineral industry grinding mill that was jointly developed in the 1990s by Mount Isa Mines Limited ("MIM", a subsidiary of MIM Holdings Limited and now part of the Glencore Xstrata group of companies) and Netzsch Feinmahltechnik ("Netzsch"), a German manufacturer of bead mills. The IsaMill is primarily known for its ultrafine grinding applications in the ...

The concentration of zinc, lead and silver in the mineralized rock extracted from the Jayula and Tesorera pits in the San Cristóbal mine is very low; it is therefore necessary to have the material undergo a process designed to increase the content of these elements and thus obtain products with a commercial value. In this sense, the concentration plant was designed to obtain two enriched ...

The physicochemical properties of both the leadzinc mill tailings and fuming furnace slag (FFS) have been examined. In the first set of experiments, raw slag (FFS) was used for paste backfill preparation and experimentation for uniaxial compressive strength (UCS) development, whereas in the second set of experiments, FFS was crushed to 75 ...

The fall in lead and zinc metal prices from 2018 to early 2020 made it harder for zinclead projects to attract interest. However, a reversal in investor sentiment in H2 2020 towards the short and mediumterm economic outlook has rejuvenated interest in leadzinc projects. This insight dives into mine project details covered by our zinc and ...

Thus, under exactly the same conditions of machine, air bubbles, frothing oil, and time of floating, more of one pure sulphide mineral will be floated than of another. The order for the four common sulphides is copper, lead, zinc, and iron. Lead and copper are rather close together but zinc is decidedly lower in floatability and iron still lower.

The Black Angel mine on the west coast of Greenland provides an example of improvements in milling practice. The mill here processed ore containing 3% lead and 10% zinc and dumped 600 Gg of tailings per year into its adjacent fjord (Asmund, 1992). An example of earlier losses to tailings is found in a study for remediation of the tailings dumps ...

At present, the treatment of tailings is mostly carried out in the form of stacking in tailings ponds, resulting in a huge waste of mineral resources and a major threat to the environment and ecology. Using tailings instead of a part of the cement to make cementitious materials is an effective way to reduce the accumulation of tailings. In this paper, leadzinc tailingsbased cementitious ...

The accumulation of mine tailings on Earth is a serious environmental challenge. The importance for the recovery of heavy metals, together with the economic benefits of precious and base metals, is a strong incentive to develop sustainable methods to recover metals from tailings. Currently, researchers are attempting to improve the efficiency of metal recovery from tailings using bioleaching ...
