  • Chapter 4: Mining waste

    CHAPTER 4: MINING WASTE. This chapter covers the different types of mining waste, how they are formed and how they are disposed of or used. Mining operations can generate enormous amounts of waste (i.e. waste rock and tailings) that must be managed and handled in a way that avoids negative environmental impact.

  • Mining and Extraction: Oxide Ores

    Copper is refined from ores in the ground, either through underground or open-pit mines. Most of the copper ores mined today are oxide or sulfide ores. Extraction of sulfide ores is covered in more detail in Copper Mining and Extraction: Sulfide Ores (11–14), but is introduced here because an important by-product of this process is used for the extraction of oxide ores.

  • Copper Mining and Extraction Sulfide Ores

    This KS3 education resource looks at copper mining, extraction and pyroprocessing of sulfide ores. Processing Stages Stage 1: Crushing and grinding The ore from the mine contains about 2% copper. To get at the copper the first stage is crushing in huge

  • Dilution and ore recovery

    Mine dilution occurs due to the mining method selected and from overbreak during the mining process. There are multiple considerations in terms of dilution. Mining methods such as block caving, sublevel stoping and room-and-pillar have mining methods which are more predictable, where dilution can be modeled using empirically generated equations.

  • Introduction to Mineral Processing

    Introduction to Mineral Processing 3 example, an ore containing the mineral chalcopyrite (CuFeS2) derives its value from the contained copper. Chalcopyrite does not in and of itself have any direct use as a mineral. Once chalcopyrite is concentrated
