Abstract: The present invention describes a method intended for lignin recovery, said method comprising: a step of mixing a stream of black liquor with an acidic biomass stream for providing a mixed heterogenous stream; a step of separating the mixed stream in a separation unit for providing one aqueous light phase stream and one lignin-containing heavy phase stream.
