ABSTRACT:
A method for treating particulate solids such as coal to reduce the cohesive strength of such solids when frozen which consists of spraying said solids with a hydrocarbon liquid solution of a balanced blend of surfactants which blend will form a single phase microemulsion at 20.degree. C. when added to water at the salinity of the water on said solids at a water to hydrocarbon ratio in the range between 99:1 and 85:15, said blend represented by the monoethanol amine salt of dodecyl o-xylene sulfonic acid and a dinonylphenol reacted with 9 moles of ethylene oxide, onto the wetted surface of said solids to form a single phase microemulsion which is optimally designed to undergo a lipophilic shift upon contacting the surface of said particles whereby an in-situ water-in-oil coarse emulsion is formed on the surfaces of said particles.
