Process for the recovery of oil
 Heavy oil or crude oil spills in sea water are recovered without polluting environment. A natural rubber latex and a coagulant are scattered around lumps of oil spills to coagulate the latex with the coagulant, so that a membrane of the latex is formed around the oil lumps.
