  • Comminution Wikipedia

    Comminution is the reduction of solid materials from one average particle size to a smaller average particle size, by crushing, grinding, cutting, vibrating, or other processes. In geology, it occurs naturally during faulting in the upper part of the Earth's crust. In industry, it is an important unit operation in mineral processing, ceramics, electronics, and other fields, accomplished with

  • Geometallurgy Wikipedia

    Geometallurgy relates to the practice of combining geology or geostatistics with metallurgy, or, more specifically, extractive metallurgy, to create a spatially or geologically based predictive model for mineral processing plants. It is used in the hard rock mining industry for risk management and mitigation during mineral processing plant design.

  • Mineral processing energy.gov.au

    Valuable minerals are extracted from rock via the process of comminution (crushing and grinding). In the mining and mineral processing sector, most energy use and greenhouse gas emissions derive from comminution, separation (froth flotation) and concentrate drying. Of these areas, comminution is the most energy intensive. In some mining sub-sectors, such as gold, copper and nickel, comminution

    The grinding media in a Rod mill are long rods of particular material which grind the ore by tumbling within the mill. The grinding action is by line contact between the long rods. There is a very minimal slime production since rods tumble and spin in roughly parallel alignment and produce size reduction of coarse ores efficiently.
