The document discusses in-pit crushing and conveying (IPCC) systems used in open pit mines as an alternative to truck haulage. It describes IPCC systems as using mobile, semi-mobile, or fixed crushers along with conveyors to transport material within the mine.

The tailings pond at the Volcanogenic Massive Sulphide copper-zinc-silver-gold Myra Falls Mine on Vancouver Island is shown on Figure 8.2.3. The tailings are contained by an embankment. ... breaking and crushing rock, and so dust is created. Some of this material is metal-rich, and is fine enough to be wind-borne, and so can be …

In this study, high voltage pulse breakage was used to study the breakage process of copper ore. The particle size, shape coefficient and preferential crushing index (Δ α i) were determined using systematic experiments.The parameters were further investigated by fitting the energy consumption model of breakage to the experimental data.

High-pressure grinding rolls (HPGR) are an accepted, but continuously expanding, comminution technology. The copper industry has a growing need to process harder ores with progressively lower grades, more challenging metallurgy and increasing demand for efficient bacterial leaching applications. This has resulted in a major focus …

used in the third stage of crushing instead of fine crushing, or at high hardness of ores in the fourth stage of crushing, which enables the ore to be softened before ball milling. The ore-processing flowsheet at the Metcalf mill (United States) includes two stages of crushing: coarse crushing in a gyratory crusher and
