A selective or sequential flotation flowsheet of two or more products. By utilizing selective flotation, two or more minerals in an ore are separated into individual high grade products. ORE TREATED: The most common of ores treated in this manner are lead zinc, copperzinciron, coppernickel, but application may be made to other two or three ...

Simulated wastewaters (concentrate and tailings thickener overflows), from a future leadzinc flotation separation plant, were treated for the removal of target metal ions (Zn 2+, Pb 2+ and Cu 2+) and suspended solids ( g L −1).The ions were adsorbed onto ferric hydroxide precipitates, and then removed by dissolved air flotation (DAF).

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 ...

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 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].

Complex and nonsulfide leadzinc ores are difficult to concentrate, but the growing demand for lead and zinc metals necessitated their beneficiation. Froth flotation is practically the most effective method in their beneficiation when optimum flotation conditions are attained. The aim of the current study is to use process mineralogy as a tool to understand the flotation behavior of these ...
