We herein provide an in depth characterization of protein recovery through acetone precipitation In 80 acetone the precipitation efficiency for six of 10 protein standards was poor ca ≤15 Poor recovery was also observed for proteome extracts including bacterial and mammalian cellsThe precipitation is preferably effected at a pH value of 15 to 20 The free hydrocyanic acid is recovered as alkali cyanide or alkaline earth cyanide and is recirculated to the leaching stage A process is described by which copper and optionally silver and gold are recovered from sulfide and oxide ores concentrates or slag which contain the metals
