the water carries the slag in its slurry format to a large agitation tank, from where it is pumped along a piping system into a number of gravel based filter beds. the filter beds then retain the slag granules, while the water drains away and is returned to the system. when the filtering process is complete,.
the agustawestland aw139 is a 15-seat medium-sized twin-engined helicopter developed and built by agustawestland, now called leonardo. it is marketed at several different roles, including vip/corporate transport, offshore transport, fire fighting, law enforcement, search and rescue, emergency medical service, disaster relief, and maritime patrol.
the mechanical agitator is equipped with a motor which drives a mixing and pumping turbine. this turbine ds the two phases from the settlers of the adjacent stages, mixes them, and transfers this emulsion to the associated settler. the mixer may consists of one or multiple stages of mixing tanks. common laboratory mixers consist of a single .
monazite is a reddish-brown phosphate mineral containing rare-earth metals.it occurs usually in small isolated crystals.it has a hardness of 5.0 to 5.5 on the mohs scale of mineral hardness and is relatively dense, about 4.6 to 5.7 g/cm 3.there are at least four different kinds of monazite, depending on relative elemental composition of the mineral: .
liquid breathing is a form of respiration in which a normally air-breathing organism breathes an oxygen-rich liquid such as a perfluorocarbon , rather than breathing air.. this requires certain physical properties such as respiratory gas solubility, density, viscosity, vapor pressure, and lipid solubility which some, but not all, perfluorochemicals perfluorocarbon have.
starch gelatinization is a process of breaking down the intermolecular bonds of starch molecules in the presence of water and heat, allowing the hydrogen bonding sites the hydroxyl hydrogen and oxygen to engage more water. this irreversibly dissolves the starch granule in water. water acts as a plasticizer. three main processes happen to the .
vat leaching involves contacting material, which has usually undergone size reduction and classification, with leach solution in large vats. tank leaching. stirred tank, also called agitation leaching, involves contacting material, which has usually undergone size reduction and classification, with leach solution in agitated tanks. the agitation can enhance reaction kinetics by enhancing mass transfer.
leaching is a process widely used in extractive metallurgy where ore is treated with chemicals to convert the valuable metals within into soluble salts. these can then be washed out and processed to give the pure metal; the material left over is commonly referred to as tailings .
