摘要： Methods of separating one type of nanoparticle from another type of nanoparticle in a mixture including more than one type of nanoparticle are disclosed. The methods may include suspending a mixture of the various types of nanoparticles in a liquid and modifying a characteristic of the liquid. Thereafter, a force may be applied to the nanoparticles within the mixture causing one type of nanoparticles to separate from another type of nanoparticles. The applied force may be the force of gravity, or it may be an induced force such as a centrifugal force applied with a centrifuge or similar apparatus. Upon the occurrence physical separation, sub-populations of nanoparticles may be removed from the suspension or segregated. Alternatively the methods may include modifying a type of nanoparticle in suspension. Alternative embodiments include nanoparticles modified in suspension to provide for separation from other types of nanoparticles.

摘要： An improved process for reducing sulfur oxide emissions from the combustion of coal is disclosed wherein a fuel mixture comprising calcium-containing sorbent and coal is fed to the burners and sulfur oxides react with calcium from the sorbent in a high temperature sulfur capture region, followed by additional sulfur capture in a lower temperature, high humidity sulfur capture region prior to separation of particulates from the flue gas. Sulfur capture using calcium-containing sorbents can be combined with aggressive coal beneficiation techniques to further enhance reduction of sulfur oxide emissions. The process of the invention provides a process for reducing sulfur oxides that efficiently uses calcium-containing sorbents to enhance sulfur capture while reducing the need for expensive equipment or process modifications.

摘要： In an ore cleaning process the underflow from an ore classifying cyclone is delivered to a heavy medium cyclone where the ore is cleaned. The underflow leaving the classifying cyclone is continually measured for specific gravity and flow rate while the specific gravity of heavy medium that can be applied to the underflow is continually measured. The amount of this heavy medium and the amount of water required to be added to the underflow are continually controlled as functions of the specific gravity and flow rate thus measured, whereby a substantially constant specific gravity and flow rate of the underflow is maintained as it enters the heavy medium cyclone. Magnetic separating means receive the overflow from the heavy medium cyclone and separate the heavy medium from the ore, while other magnetic separating means receive the underflow from the same cyclone and separate the heavy medium from the rejects. The heavy medium is used again.

摘要： Brucite in finely divided condition is collected as a high grade concentrate of brucitic ores and other magnesium hydroxides by selective temperature control of heavy liquid media during continuous treatment. Ore is initially assayed to determine the specific gravity of its brucite content and methylene bromide as heavy liquid media will be used at its usual specific gravity of 2.48 at ambient temperature. If higher grade product is desired, changes in temperature of media are developed to obtain density drop to 2.40, for example. To change back to normal production media temperature is adjusted and no change in media composition is required.
摘要翻译：在连续处理过程中通过选择性温度控制重质液体介质，收集细分条件下的水镁石作为高品位的高岭土矿物和其他氢氧化镁的浓缩物。最初测定矿石以确定其水镁石含量和二溴甲烷的比重，因为重质液体介质将在环境温度下的常规比重为2.48时使用。如果需要较高级别的产品，则开发介质的温度变化以获得例如2.40的密度下降。要恢复正常生产，调节介质温度，不需要改变介质组成。
