Abstract
The present invention relates to an improved method of recovering rubber from skim natural rubber latex. The method comprises pre-treating the skim latex, concentrating the skim latex using one membrane module or two membrane modules in series with addition of potassium hydroxide or a solution containing ammonium laurate and potassium hydroxide, optionally treating the concentrated skim latex with a tetramethylthiuramdisulphide (TMTD) and zinc oxide (ZnO) dispersion, blending the concentrated latex with fresh field latex, centrifuging the blend to obtain a latex concentrate. The latex concentrate is further blended with a fresh latex concentrate and treated with ammonia to obtain the final latex concentrate
