Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. Froth flotation efficiency is determined by a series of probabilities: those of particle–bubble contact, particle–bubble The collision rates for fine particles (50 - 80 μm) can be accurately modeled, but there is no current theory that

effects of natural gas price on ammonia production costs (note-may not include all capital costs).4 Currently (September 2005), spot prices for natural gas are in the range of $10-11/MMBtu. Extrapolating the trend shown in the figure, the estimated cost of ammonia production would then be $377/ton for a natural gas price of $10.50/MMBtu.
Mineral storage. In mineral storage, captured CO 2 is reacted with naturally occurring iron (Fe) magnesium (Mg) and calcium (Ca) minerals. This is called mineral carbonation and occurs naturally in the weathering of rock over time. Such minerals are very abundant and very stable. As a result, the re-release of CO 2 into the atmosphere does not
