摘要： Methods for reducing moisture content of alkaline earth metal carbonate may include introducing alkaline earth metal carbonate having a moisture content ranging from about 0.1% by mass to about 10% by mass into a primary crusher and operating the primary crusher to obtain alkaline earth metal carbonate particles having a top cut particle size d90 of 90 microns or less. The method may also include introducing the particles into a primary grinder and operating the primary grinder to obtain reduced-size alkaline earth metal carbonate particles having a median particle size d50 of about 60 microns or less. The method may further include introducing the reduced-size particles into a classifier mill and operating the classifier mill to obtain further-reduced-size alkaline earth metal carbonate particles having a median particle size d50 of about 12 microns or less, and a moisture content of about 0.15% by mass or less.

摘要： Disclosed is an apparatus that is an attrition mill for grinding or comminuting ores, mine wastes, and radioactive wastes some of which may comprise metals, which may include uranium and/or cesium and/or mercury and/or thorium and/or rare earth elements. Also disclosed are processes that employ the apparatus for combined grinding and optionally leaching metals from ores and wastes. Some such methods comprise an optional step of grinding and mixing the ore or waste with a solid inorganic base with water addition or with an aqueous inorganic base, follow by a step of grinding and mixing the ore or waste with an aqueous inorganic acid with or without leaching salt addition, to solubilize the metals present in the ore or the waste. The disclosed apparatus and methods, in some embodiments, enable efficient grinding and attrition of ores substrates and mine wastes even without need for grinding media.

摘要： Disclosed herein are methods and apparatus for producing nanometer scale particles utilizing an electrosterically stabilized slurry in a media mill. A method for producing nanometer scale particles includes adding to a media mill a feed substrate suspension. The feed substrate suspension includes a liquid carrier medium and feed substrate particles. The method further includes adding to the feed substrate suspension in the media mill an electrosteric dispersant. The electrosteric dispersant includes a polyelectrolyte. Still further, the method includes operating the media mill for a period of time to comminute the feed substrate particles, thereby forming nanometer scale particles having a (D90) particle size of less than about one micron, and recirculating for further grinding the nanometer scale particles from the media mill.
