    • A process for producing raw rubber from a deproteinized natural rubber is disclosed, which comprises coagulating rubber particles in the deproteinized natural rubber latex by: (1) adding a nonionic surfactant having a cloud point of from 20.degree. to 100.degree. C. and a molecular weight of 300 or more to the deproteinized natural rubber latex and heating the latex to a temperature not lower than the cloud point of the nonionic surfactant; or (2) adding a coagulation assistant selected from the group consisting of: (a) an anionic surfactant, (b) an amphoteric surfactant, (c) a nonionic surfactant, (d) a nonionic or amphoteric oligomer or polymer, and (e) an anionic oligomer or polymer, to the deproteinized natural rubber latex; and then recovering the coagulated rubber particles. According to the process of the present invention, raw rubber containing substantially no metal ion can be produced with a high efficiency.
