Abstract: The invention is directed towards methods and compositions for treating piles of low-rank coal to inhibit its spontaneous combustion. The method involves applying to the low-rank coal a composition containing VAE and crude glycerin. The composition prevents water from evaporating out of the low-rank coal. This prevents the formation within the low-rank coal of hollow openings which are a huge factor in causing its spontaneous combustion. The composition has better performance than its ingredients do alone. In fact it is so effective that certain cumbersome low-rank coal-handling methods, such as FIFO recordkeeping and inventorying, not using pinch points, or only using elbow-free equipment can be disregarded when the composition is used.

Best of all the composition is easy to form and easy to introduce into a water stream of concern. Its introduction can be as simple as mixing two containers of reagent prior to introduction to the water process stream.

Abstract: The invention provides a method of improving a flotation separation process. The method involves PAPEMP, a material previously thought to only be of use in controlling scale deposit on surfaces of equipment used in cyanide leaching. In the invention the PAPEMP is added to the flotation separation process for improved sulfide mineral separation. Not only does the addition of PAPEMP improve the overall recovery of sulfide complexed metals in flotation, but by doing so it also reduces the energy requirements and adds other efficiencies to other downstream ore processing and refining steps. This has the added benefit of helping to preserve the environment.

Abstract: The invention provides a method of recovering and recycling waste coating color from papermaking coating process for use as wet end filler. The inventive method overcomes many technical challenges inherent in using waste coating colors as wet end filler such as the coatings having fine pigments that hurts sheet strength more than regular filler, having strong anionic charge and tendency to disturb wet end chemistry, causing excessive foaming, and containing a large amount of hydrophobic binder particles that tend to agglomerate in the white water and deposit on papermaking equipment. The method involves mixing the coatings with fresh filler particles, adding de-foaming agent, adding cationic coagulant, then preflocculating the mixture. This process causes fresh filler particles, pigments and binders in waste coating color to agglomerate together and form stable flocs with defined particle size distribution.
