The Lead/Zinc Concentrator of Mount Isa Mines Limited processes complex fine grained ore from the Isa and Hilton silverleadzinc orebodies, producing lead concentrate, zinc concentrate and (until 1996) a low grade middlings (LGM or bulk) concentrate. Metallurgical performance declined dramatically during the 1980's because of declining ore quality, as the ore became both finer grained, and ...

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 first improvement was the use of a lead salt; this was achieved by dipping the bundles of zinc shavings in lead acetate. • The second was the substitution of zinc powder in place of the zinc shavings ( Merrill). • The third was the introduction of deaeration through the use of a vacuum deaeration tower ( Crowe).

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 leadzinc mill tailings differ from other materials used in previous studies in terms of host rock type (leadzinc tailings are of calcsilicate dolomite and graphite mica schist) and physicochemical properties. These properties have a direct impact on the mechanical properties/strength development of paste backfill materials [20,37,43,44].

As the result of this development, a 3000 litre and MW motor power unit was designed and installed, first in Mount Isa Mines lead/zinc concentrator (1994, two mills) and then at McArtur River Mining (1995, five mills). In 2001 six more mills were installed at the Mount Isa Mines lead/zinc concentrator.

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 ...
