  • cocrystal

    cooling molten mixture of cocrystal formers often affords cocrystals. seeding can be useful. another approach that exploits phase change is sublimation which often forms hydrates. grinding, both neat and liquid-assisted, is employed to produce cocrystal, e.g., using a mortar and pestle, using a ball mill, or using a vibratory mill. in liquid .

  • knelson concentrator

    a knelson concentrator is a type of gravity . high speed by an electric motor and a pressurized water jacket encompassing the bowl. feed material, typically from a ball mill discharge or cyclone underflow bleed, is fed as a slurry toward the centre of the bowl from above. the feed slurry contacts the base plate of the vessel and, due to its rotation, is thrust outward. the outer extremities .

  • comminution

    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 many types of mill. in dentistry, it is the result of mastication of food. in general medicine, it is one

  • geometallurgy

    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. it is also used, to a lesser extent, for .

  • cupellation

    process large scale cupellation. native silver is a rare element, although it exists as such. it is usually found in nature combined with other metals, or in minerals that contain silver compounds, generally in the form of sulfides such as galena lead sulfide or cerussite lead carbonate . so the primary production of silver requires the smelting and then cupellation of argentiferous lead ores.
